AWS: What is Kafka and MSK service ?

What is Kafka and MSK service ?

In this blog I have presented the videos on:

  1. What is Kafka ? : https://www.facebook.com/347538165828643/videos/405168210472204/
  2. What is MSK services for Kafka on AWS?: https://www.facebook.com/347538165828643/videos/233592261348312/
  3. How to config the Kafka in EC2-Ubuntu and what are the components it has ?: https://www.facebook.com/347538165828643/videos/429917674635091

This video has the outline on AWS Data Pipeline service.

Please follow my videos : https://business.facebook.com/vskumarcloud/

NOTE:

Let us also be aware: Due to lacks of certified professionals are available globally in the market on AWS, to differentiate them on their needs/selection, most of the clients are asking on the real experience gained or aware of IAC. They give a Console and ask you to setup a specific Infra setup in AWS.

In my coaching I focus on the candidates to gain the real Cloud Architecture implementation experience rather than pushing the course with screen operations only to complete. Through my posted videos you can watch this USP.

Contact for your real Cloud experiences learning and gaining with me and crack the interviews to get offers in AWS Roles globally or even you can transition to the role in the same company after facing the client interview/selection process. Which is very easy with this knowledge.

Please connect me on FB and have a discussion on your background and the needs/goals. I am looking for the serious learners only by having dedicated time. If you are a busy resource on the projects please note; you can wait to become free to learn. One need to spend time consistently on the practice. Otherwise its going to be in no-use.

How A Cloud architect is different from DevOps role ?

vskumarcloud-build-cloud-architect.pngHow A Cloud architect is different from DevOps practices ?

We have been watching on lot of FB Groups and ad sites as “learn DevOps/AWS”. In general everybody believe with these stickers/posters they need to learn AWS and DevOps together is a must for any Modern technology professional.

When we talk about AWS and DevOps they are two different work streams.

Now, one might get the below questions in their mind.

  1. Is a Cloud Architect need to be expert to work on DevOps activities also ?
  2. What are the activities related to Cloud architect ?
  3. Why the Cloud architect need not bother on DevOps ?

Now, let us analyze them as below:

The role of the cloud architect is to migrate the existing IT infrastructure setup into the cloud services. The cloud services can be AWS or Azure or Google cloud [GC] or Alibaba, etc.

From the below picture one can have clarity if they have experience in traditional Infrastructure building  practice.

How to create AWS S3 Bucket

This role need to understand clearly on the usage of those vendor related [AWS/AZURE/GC/Alibaba] cloud services and should have command on mapping the current traditional infrastructure setup to map to the cloud services and plan/design for its transformation with the additional benefits to the management in view of cost and easy operation.

Once the modern application architecture/infrastructure in cloud is operational, then the management can think of introducing the DevOps practices.

To work on DevOps practices, each Cloud services vendor provides their own setup or tools at different processes or pipeline stages. To do these tasks a separate role professionals are required, who are called DevOps Engineers. At this point the role of the cloud Architect is he/she can guide them on the available infrastructure with the Cloud vendor. As per the Cloud architect planning/guidelines the DevOps engineers need to adopt the relevant tools/processes. Basically all the setup is going to be on IAC [Infrastructure As A Code] technics. There can be Configuration tools to create the IAC for different environments. At this point the Cloud architect can monitor these tools implementation as a part of cloud infrastructure implementation.

So, the Cloud architect do not need to make his/her fingers dirty with tools/commands to implement the DevOps processes.

For example; If you read the roles of AWS with different certifications, they mention Solution Architect [SA] separately from DevOps engineer role. They have multiple roles like; Sys ops, Developer, etc. All these roles need to be expert in making their fingers dirty with the relevant AWS services usage/implementation efficiently and effectively . But here the Cloud Architect [which is SA in view of AWS] role is to monitor on their activities only. He/She doesn’t need to put the fingers into techie stuff.

Hope I have given clarity for the above questions.

I get lot of enquiries; as they want to do AWS/DevOps both the courses together. I understood due to lot of training vendors are making their posters on social for their business, these experienced professionals are getting confusion as they need to learn both.

Now, I would like to ask the below questions to you as this blog reader after the above understanding;

Do a modern technology professional need to learn Cloud services and also the DevOps as mandatory ? [Ex: Which is DevOps/AWS].

Answer: It is not. They can choose One route only. If he/she came from the real work experience of Sysadmin/Sys engineer role, the past experiences need to be utilized efficiently in IT Industry. Hence the Scalable role is Cloud architect. In view of AWS it is SA. But they need to have very good command in understanding the traditional architecture and also the cloud services to establish a well suited conversion plan. This role person is responsible to  show ROI [Return On Investment] also to the management.

You can also compare the SAA Salary among all the roles being played with AWS:

See the difference on the salary amounts to seek your role as per your professional potentiality.

Question: In the current job market in the JDs they ask on DevOps also for Cloud role why ?

Answer: Please let us note; Many organizations they wanted to use the same resource for Cloud and DevOps Architect/Engineer role to save their IT budget. But they offer more salary for these multi skills. Not only this scenario, there are many companies use multi-cloud technology for their BCP. They will ask these skills also. The skills acceleration is mandated for every Professional now a days. The more skills you acquire the early, your CTC is going to touch the Sky ASAP.

Guys A NOTE for you:

Folks,
How to Join in my Facebook groups to learn Cloud cum DevOps Concepts ?
For any Trainings many people conduct demos by catching the IT Professionals through their sales people. That demo denotes the trainer has the technical capabilities to handle the course for the attendees. In my coaching also I have followed the similar concept. But I don’t give demos by spending time, as I work as alone. In my case I have created the groups in Facebook: a) DevOps Practices Group, b) Cloud Practices Group c) Free Learning Agile/DevOps/AWS/AZ for freshers and IT Professionals. With few of the web pages by IT topic.

One can learn and assess them by joining. For more details you can watch this video. To join in them, you need to connect with me on FB and Linkedin and send a message. Then only you will be approved. This is a verification process to avoid fake ids.

AWS: POC-How to Build WordPress web site in AWS Cloud/Network ?


Most of the Blogs on websites are operated by WordPress[WP] software which is developed in PHP. Even my site [vskumar.blog] is from this software. To setup the WP, there are tier based architecture/setup required. For PHP related software we can have a 2-tier architecture setup.

For detailed analysis and the required AWS components for setting up W, below blog you can visit/follow blog:
https://vskumar.blog/2018/12/31/2-aws-wordpresswp-infrastructure-creation-using-a-free-tier-account/

In this demo video the WP site building project was discussed with different design steps towards AWS components and it was demonstrated well by one of our [experienced IT Professional] students well.


These are weekly assignments they get and they need to prove by themselves with a demo in a team; like live environment how it happens in a typical project team. By attending this activity delivery on weekly basis, one will not get any fear/scareness on doing the live infra tasks. They will be habituated with the project activities when they join in real job. And they will be productive resources from day one onwards. These are the major benefits from my course.

AWS: POC-How to do VPC Peering with 2 VPCs ?

When we have two networks in traditional methods, we used to do internal networking within the premises. And used those servers for Software APIs. Also the Sysadmin/DBAs/Network Admin role people used to manage them well. But in Cloud how to implement this kind of setup ?

In this POC project, it is well proven how we can create such kind of environment by using 2 VPCs and their peering with deeper analysis and the design steps of different services. And how the private subnet related Linux and Windows EC2s can be accessed by using NAT and Jump Servers?. And how to operate another VPC EC2 from one VPC EC2 ? Just watch this design steps analysis video from the below link:

In the below video a POC analysis is discussed with an Experienced Cloud/DevOps professional.

AWS: Do you think, User IDs of IAM and EC2 are the same ?

When we talk about user ids in AWS or any Cloud some [Non-AWS Practiced] people feel user ids of IAM and EC2s are the same. But not!

  1. IAM user ids are made to access particular services of AWS Platform through some of the groups Privileges. These Groups are embeded with AWS policies to have access on the services.
  2. Where as EC2 is a Virtual Machine [can be either Linux OS or Windows server]. It needs the users to access. Like your physical machines have the used ids, the VM also has them.

AWS: What is CloudFormation ?

Watch this video for CF introduction:

This video has the demo on Cloudformation with IAC to create a simple EC2.

https://business.facebook.com/vskumarcloud/videos/2328450437268264/

Please note; every Cloud/DevOps/Test Engineer need to drive the infra setup tasks through IAC scripts only, when they are advanced in infra setup understanding. For every infra setup tasks they should be able to step down to develop these IAC scripts by using different tools. In AWS, we can use CF, Terraform and Ansible very easily for the medium level config scripts building.

https://vskumar.blog/2019/07/26/aws-usage-of-cloudformation-templates-1-wp/

For a jumpstart of learning process, I have started building some videos on understanding the Infra scripts process through CF Templates with POCs/demos. Following link has these videos to watch and do self practice with CF.

Please follow my videos : https://business.facebook.com/vskumarcloud/

Once you are perfect you can choose any of the Infra CM Tools to write scripts and run for automated infra setup.

The samples are made with the below infra setup scenarios:

1. Cloud Defects:How the Cloud Professionals can Create the costly defects and the reasons ?

With reference to the booming Cloud Market [refer to some of my videos/blogs] and the Conversions to Cloud by different business organizations; Globally millions of IT professionals were mandated to learn the Cloud technologies to sustain their jobs in IT.

When we talk about these converted IT Professionals, they were forced to move into Cloud due to the sustainability of their job.

At the same time their employers are also enforced by their management to accelerate the cost savings for IT infra.

So how they do the planning for Cloud ?

On top there can be a CTO/CIO plans it to convert into Cloud. And they have the complete knowledge of the infrastructure with reference to their technology being used for business systems.

There will be Cloud Architects, they are responsible to create the Cloud implementation design.

Then the plan and the design is released to the Cloud engineers by allocating the tasks.

In between due to lack of [turn around] time, the Cloud engineers are pressured to create the environments. Here everybody can find one point, the management did not plan the knowledge transfer perfectly to the low level people. Then they can create many costly defects as per their knowledge and experience. So there is no ‘uniformity was followed’ in this case. It need not be a cost effective solution the Cloud Architects or Cloud Engineers have done. And there was no review also done. Once the monthly Cloud bill is arrived they will realize on it. Then they can realize the costly burning/bill happened by comparing to their planned cost saving on Infra. So this way they are enforced to track the resources who created these costly defects.

The following picture has got this kind of analysis. And what are the basic reasons the Architects and Engineers are not able to understand the domain conversion scenarios, when the management plans and release it for implementation.

Here we need to remember, every IT Professional need to realize that one fine day the current size of the resources will not be there in any project due to Cloud and the automation implementation is happening.

So the self matured professional need to realize where they are lacking and step down to learn those from experts, on war footing basis to prove and safeguard their jobs in IT.

If you want to learn the details, I have discussed in the below video with the relevant coaching on AWS-SAA course also.

DevOps: What are the Differences between containers and VMs ?

What are the Differences between containers and VMs ?

During Deployment activity phase the environment building is part of the DevOps practices.

In traditional method we used to spend lot of time for this task. But when it came with VMs and containers, it is easy and in minutes the environments can be prepared using the IAC.

The containers became very popular for building the test environments. Let us say you want to build a MYSQL server, the solutions is; simply try to understand its environment and pull one Docker image which has the MYSQL. Then use it in that network environment.

When we talk about the VMs and Containers one need to understand their differences. I have made a video for learners:

If you are a Docker learner, then try to build the MYSQL container from the below specifications:

DevOps: Advanced DevOps Practices/Processes-2 [DevSecOps]

In continuation of my previous blog on; DevOps:Advanced DevOps Practices/Processes-1:
Following are the some of the DevOps concepts, a Practitioner need to practice.

What is the goal of DevSecOps?

The goal of DevSecOps is to decrease time to market while cutting the costs of development and remediation, while improving overall application security.

How it can be performed ?:

If the appropriate, automated security vulnerability and configuration scanning tools are deployed, developers with varying skill sets and experience can find and fix security problems as they occur.

How to motivate developers?:

Teaching developers on secure coding practices is still essential,  as it is monitoring and protecting the production environment.

How to achieve it?:

By integrating automated application security testing as part of the moving into DevSecOps practices, teams can complete a DevOps security checking that addresses the challenges associated with developing secure applications in agile environments.

How to apply checkpoints?:

There are tools to verify the above checks.

I have discussed some of the relevant points on this subject in the below video session:

AWS: Usage of CloudFormation Templates for IAC

Through this blog I would like to demonstrate on CloudFormation [CF] templates usage with the IAC.

I have observed in Cloud and DevOps teams, many of them are non-programming background. But when the Infra setup requirement comes into their task following questions will arise:

  1. How can they write the JSON/YAML/Go programming/script coding ?
  2. How can they understand the Cloud services and the domain setup knowledge ?
  3. What are the sequence of steps they need to follow, if they are being asked to setup the environments?
  4. How the VPCs need to be built ?
  5. How the Load Balancers need to be setup ?
  6. How the autoscaling and load balancing can be done in different locations to balance the traffic and maintain the infra setup consistency with low latency ?
  7. What are steps need to be followed to learn on the above process/procedures ?

AWS has given some of the infra setup the CloudFormation templates for us to try and test them. And later on to understand the Script/code of JSON/YAML to implement with any CM Tools.

Please visit the below blog for samples of YAML/JSON IAC discussion videos:

2. AWS IAC-YAML: How to work with CF for various infrastructures setup ? | Building Cloud cum DevOps Architects (vskumar.blog)

Please note; every Cloud/DevOps/Test Engineer need to drive the infra setup tasks through IAC scripts only. For every infra setup tasks they should be able to step down to develop these IAC scripts by using different tools. In AWS, we can use CF, Terraform and Ansible very easily for the medium level config scripts building.

For a jumpstart of learning process, I have started building some videos on understanding the Infra scripts process through CF Templates with POCs/demos. Following links have these videos to watch and do self practice with CF.

How to Create a simple WordPress website with CloudFormation[CF] in AWS ? :
In this POC exercise, we are using the Readily available template from the CloudFormation[CF] stacks with detailed lab steps in the below attached Video. There are two categories of WP infra building CF Templates mentioned in the CF stacks. In this example initially, I have taken the simple setup without Load balancer and Autoscale setup. The specifications/guidelines are given clearly to follow through video.

Let us also be aware: Due to lacks of certified professionals are available globally in the market on AWS, to differentiate them on their needs/selection, most of the clients are asking on the real experience gained or aware of IAC. They give a Console and ask you to setup a specific Infra setup in AWS.

In my coaching I focus on the candidates to gain the real Cloud Architecture implementation experience rather than pushing the course with screen operations only to complete. Through my posted videos you can watch this USP.

Contact for your real Cloud experiences learning and gaining with me and crack the interviews to get offers in AWS Roles globally or even you can transition to the role in the same company after facing the client interview/selection process. Which is very easy.

Please connect me on FB and have a discussion on your background and the needs/goals. I am looking for the serious learners only by having dedicated time. If you are a busy resource on the projects please note; you can wait to become free to learn. One need to spend time consistently on the practice. Otherwise its going to be in no-use.

What are the Skills required for a Cloud Architect ?
How best you can utilize this role as efficient IT Management practitioner ?
Many organizations use the role of Cloud Architect for DevOps Practices also in small to mid size IT Organizations or departments.
But in reality if the organizations want to implement effectively and efficiently the Cloud migrations, they need to dedicate the Cloud Architect role as per the standards.
You can also watch the below video to know what kind of activities and planning need to be done for Cloud initiation. This was published by me on May 21, 2014.

You can also see:

What is the need of upgrading cloud skills for a PM role ?

 
In 2017, Gartner published on Cloud Architect role with many activities along with the required skills. We may not be able to use the entire activities related to this role. But there are some mandated activities we can use them in regular business.
I have extracted some of the important points where in the current trend the IT Management practitioners can utilize them and see the differentiation from your past executions on this role. A discussion video is attached below for your perusal.
Finally, I would say you are mandated to separate this role from DevOps Activities assigning and dedicate the role for;
  • Cloud Infrastructure Planning,
  • Designing,
  • Building and
  • implementing effectively for business needs 
So many burning issues related to DevOps and Cloud can be separated and resolved faster to move forward. This way many risks can be reduced!!
If you are an IT management practitioner; and would like to get any clarifications to implement these practices you are advised to contact me on FB and have a call.

2. AWS POC : WordPress[WP] infrastructure creation using a free tier account

With reference to my previous blog on:
1. AWS:How to create and activate a new account in AWS ?
https://vskumar.blog/2018/09/01/1-awshow-to-create-and-activate-a-new-account-in-aws/

I have made a scenario based “AWS services usage” blog in this content. Which can be considered as a Proof of Concept [POC] Project also.

If you are new for cloud technology, I have made a video cum blog for you to understand its initiation/evaluation concepts. This video is more useful for PMs/Cloud Architects/DevOps role based people.

For video Visit:

For the above video’s blog:

https://vskumarcloudblogs.wordpress.com/2016/11/30/how-to-initiate-a-cloud-transformation/

Now, let us move forward with this blog content.

In this AWS exercise, I have described/demonstrated on WordPress[WP] infrastructure creation using a free tier account.

At the end of this blog a micro level lab practiced steps are copied and a recorded video is there on my channel.

I would like to explain from architecture/design perspective through this blog, before you go to Lab steps.
After doing this exercise, simply and finally we can come into the following conclusions:

a) Creating a blogging infrastructure can be fully automated through AWS services.
b) Infrastructure can be created at any time on-demand without any up-front
commitment for how long we will use it in AWS.
c) We can pay for our infrastructure depending on how many hours we use it.
d) Infrastructure consists of several parts,
such as; i) virtual servers, ii) load balancers, and iii) databases.
e) Infrastructure can be deleted with one click without costing to us.

This process is powered by AWS automation. So it will not be billed to our free tier account after deletion!!.

First let us analyze on WP and its components.

How a WordPress infrastructure can be planned?

Assume we have a startup company, which publishes more white papers and  blogs.

Assuming; our startup company currently uses WordPress[WP]  to host over 500 blogs on our own servers.  The blogging infrastructure must be highly available, because customers don’t tolerate outages of any servers.  To evaluate whether a migration is possible through AWS services, we need to do the following three Activities planning and try out with AWS free-tier account:

A) Set up a highly available blogging infrastructure in AWS.
B) Estimate monthly costs of the infrastructure.

C) Finally, Delete our blogging infrastructure to save cost from free-tier account.

For our understanding on WP;

  • WordPress[WP] is written in PHP and uses a  MySQL database to store data.
  • Apache is used as the web server to serve the blog pages.
  • With this information in our mind, we map our requirements to AWS services  to test the infrastructure creation.

Now, let us analyze on “what are the AWS services required for our WP test infrastructure?”.

We need  the below AWS services to do this activity:
I. Elastic Load Balancing (ELB),
II. Elastic Compute Cloud (EC2),
III. Relational Database Service (RDS) for MySQL and
IV. Security groups.

Let us analyze what are the functions/benefits of  these AWS services.

I. Elastic Load Balancing (ELB):

AWS offers a load balancer as a service.
The Elastic Load Balancer (ELB) distributes traffic to a bunch of servers behind it in a cloud environment. It’s highly available by default.

Let us assume our startup company’s blogs are published globally. From many countries these can be accessed by the users. Assume there are lot of users access this content globally. Then in traditional method your load is not balanced without  having physical servers connected through VPNs/networks, etc. in different locations. Think about the Hardware/Software/maintenance/FMG cost for this traditional infrastructure. We can not think it being a startup company to spend much. No way!! Hence we need to depend on cloud service provider.

With AWS ELB, this can be balanced by distributing the blog users traffic to different virtual servers under cloud environment. To denote this distributed load balancing  architecture, I have collected a diagram  on;

WordPress infrastructure and Load Balancing through ELB AWS service.
Which is pasted here for your clarity on the ELB function.

WP-Infra-ELB-load Distribution.png

II. Elastic Compute Cloud (EC2):

It is A virtual server which is provided by the Elastic Compute Cloud (EC2) service of AWS. We will use a Linux server with an optimized distribution called Amazon Linux to install Apache, PHP, and WordPress during our exercise. Please note; we are not limited to Amazon Linux only; we can also choose Ubuntu, Debian, Red Hat, or Windows. Virtual servers can fail at any time, so we need at least two of them for contingency planning. The load balancer will distribute the traffic between them. The beauty of AWS service in case of a server failure is; the load balancer will stop sending traffic to the failed server, and the remaining [contingency] server will need to handle all the requests until the failed server is replaced. Let us not worry on this communication! You will be intimated the status through alerts.

A sample architecture diagram is pasted here FYI with two EC2 instances.

EC2-two instance-ELB-Scenario.png

III. Relational Database Service (RDS) for MySQL:

WordPress relies on the popular MySQL database. AWS provides MySQL as a Relational Database Service (RDS). We can choose the database size (like; storage, CPU, RAM), and RDS takes care of the rest (backups, updates). RDS can also provide a highly available MySQL database by replication. In traditional [non-cloud] model we had the similar setup. It occurs huge costing. By using AWS cloud services this can be easily maintained with minor costing only.

On this context; from the below diagram we can see the MYSQL features from AWS services offering.

AWS-MYSQL-RDS-features

V. Security groups:

In every application architecture we need to have the security features in place. Either these can be embed in the applications or through security tools it can be applied. So the entire architecture is protected that way.

But in cloud services many providers provide these services differently with their services offering.

The Security groups are a fundamental service of AWS to control network traffic like a firewall in traditional systems. Security groups can be attached to a lot of services like ELB, EC2, and RDS. For example; with security groups, we can configure our load balancer as below:

It only accepts requests on port 80 from the internet. Web servers only accept connections on port 80 from the load balancer. And MySQL only accepts connections on port 3306 from the web servers. If we want to log in to our web servers via SSH, we must also open port 22. Similar ways the architecture setup can be configured.

FYI, I have considered a diagram from AWS docs; which denotes a typical AWS multi-tier approach security services with a Firewall:

AWS-Security mulit-tier aproach.png

As shown in the above diagram, A security group acts as a virtual firewall for our instance to control inbound and outbound traffic. When we launch an instance in a Virtual Private Cloud[VPC], we can assign the instance to up to five security groups. It means in any VPC  AWS provides five different security groups.

So, now what is our start company plan for security?:

Let us assume our startup company’s blogging infrastructure consists of two load-balanced web servers running a) WordPress and b) a MySQL database server.

The following tasks are performed automatically in the background through AWS:

  1. Creating an ELB.
  2. Creating a RDS MySQL database.
  3. Creating and attaching security groups.
  4. Creating two web servers.
  5. Creating two EC2 virtual servers.
  6. Installing Apache and PHP via yum.
  7. Install php, php-mysql, mysql, httpd.
  8. Downloading and extracting the latest version of WordPress from http://wordpress.org/latest.tar.gz   
  9. Configuring WordPress to use the created RDS MySQL database 
  10. Starting Apache. 

Before going to the above steps, I would like to show the below diagram for your understanding on “The setup of WP hosting on AWS”. You can download it through the URL given and see it as an image file for your understanding.

AWS-WP-Hosting setup

Now, let us recap our beginning conclusions for this blog. We need to do the below activities till end of the exercise.

  1. Creating a blogging infrastructure.

  2. Analyzing costs of a blogging infrastructure.

  3. Exploring a blogging infrastructure.

  4. Shutting down a blogging infrastructure.

  5. Deleting infrastructure from AWS Account.

1. What actions we need to consider for Creating blogging infrastructure in AWS?: To create the blogging infrastructure we need the below steps to follow on AWS console.

Note: Please note time to time the screen flows [micro level steps] might change on AWS, but the process should be the same to understand on creation of this WP infra.

  1. Open the AWS Management Console at https://console.aws.amazon.com.
  2. Click Services in the navigation bar, and click the Cloud-Formation service.
  3. Click on Create Stack to start the four-step wizard.

Now we will see what are these 4 steps wizard process it contains.

I. Creating a blogging infrastructure: Step 1 of 4

You need to name your infrastructure. Enter “wordpress” as the Name. For Source option, select and  Specify an Amazon S3 Template URL as shown in the screen [lab exercise screen]. Copy this URL and save somewhere in a text file for future reference/usage. About this process, during lab demo you will understand clearly.

II. Creating a blogging infrastructure: Step 2 of 4

Click Next to set the KeyName to “vskumarkey” [example only, you can give any name], for Step 2 of 4. Click Next to create a tag for our infrastructure into next screen. These steps can be seen clearly in lab practices steps.

III. Creating a blogging infrastructure: Step 3 of 4

A tag consists of a key-value pair and can be used to add information to all parts of our infrastructure. We can use tags to differentiate between testing and production resources, add the cost center to easily track costs in our organization [if any], or mark resources that belong to a certain application if we host multiple applications in the same AWS account.

In this example, we will use a tag to mark all of our resources that belong to the “wordpress system”. This will help us later to easily find our infrastructure. Use “system” as the key and “wordpress” as the value.  Click Next. Finally, we will see a confirmation page for Step 4 of 4. For clarity look into lab steps.

IV. Creating a blogging infrastructure: Step 4 of 4

In the Estimate Cost row, click Cost. This will open a new browser tab in the background. Keep this browser open only. We will come back to this screen later. Switch back to the original browser tab and click Create. We can see next Review screen in the next page.

Now, our infrastructure will be created. This Review screen shows that wordpress is in the state of CREATE_IN_PROGRESS. It takes 15-20 mts to complete this process.

Now, please take a look at the result by refreshing the page. Select the “WordPress” row, where Status should be CREATE_COMPLETE. If the status is still CREATE_IN_PROGRESS, be patient until the status becomes CREATE_COMPLETE.

Switch to the Outputs tab [below part of the screen], which is the Blogging infrastructure result. There we can find the URL to our “wordpress system”; click it to visit the system.

What is AWS Automation here?:

As we have discussed in the beginning of this blog, one of the key concepts of AWS is automation. We can automate everything. In the background, our blogging infrastructure was created based on a blueprint with its automation. So the above mentioned [10] tasks have been performed in the background by AWS cloud formation service. You can see the beauty of this automation during lab demonstration.

Blogging infrastructure result:

Now we’ve created our blogging infrastructure, let us take a  look at it. Our infrastructure consists of the following as we discussed in this blog:

  • Web servers
  • Load balancer
  • MySQL database

Now; we will  use the resource groups feature of the Management Console to get an overview.

Exploring the created WP Blogging  infrastructure

Now let us understand;

What is Resource Group in AWS?:

  1. A resource group is a collection of AWS resources.
  2. Resource is an abstract term for something in AWS like an EC2 server, a security group, or a RDS database.
  3. Resources can be tagged with key-value pairs. In such case; let us note we can have more than one key-value pairs.
  4. Resource groups specify what tags are needed for a resource to belong to the group.
  5. Furthermore, a resource group specifies the region(s) where the resource should reside in. It means globally these resource groups can be deployed for its functioning. 
  6. We can use resource groups to group resources if we run multiple systems in the same AWS account. This way we are sharing the resources among the projects or app architectures.
  7. Let us note that we have tagged the blogging infrastructure with the key “system” and the value “wordpress”.
  8. As an example; from now on, we will use this notation for key-value pairs: (system:wordpress). We’ll use that tag to create a resource group for our WordPress infrastructure.  For further clarity please look into the lab steps/video.

Now let us understand;

How to create  a resource group in AWS?:

    1. In the AWS part of the top navigation bar, click Create a Resource Group.
    2. Set Group Name to “wordpress” or whatever you like.
    3. Add the tag system with the value wordpress.
    4. Select the region N. Virginia [for example]. [I have used my existing account]
    5. Save the resource group.
    6. It will take you to next screen shown in next page. Follow the below steps.

How to see the Blogging infrastructure web servers via resource groups details?:

  1. Select Instances under EC2 on the left to see the web servers.
  2. By clicking the arrow icon in the Go column, you can easily jump to the details of a single web server. 
  3. Now, You are  looking at the details of your web server, which is also called an EC2 instance.

Details of web servers running the blogging infrastructure:

  1. On this screen the interesting/important details are as below:
  • Instance type: It tells us about how powerful your instance is.
  • Public IP address: The IP address that is  reachable over the internet. You can use that IP address to connect to the server via SSH.
  • Security groups: If you click on View Rules, you’ll see the active firewall rules like the one that enabled port 22 from all sources (0.0.0.0/0).
  • AMI ID: Let us recollect that we used the Amazon Linux operating system (OS). If you click the AMI ID, you will  see the version number of the OS, among others.  

We also need to know the utilization of webservers, like how we used to monitor in live [for production boxes].

Looking for webserver utilization and metrics in AWS:

2. In the screen; Select the Monitoring tab to see how your web server is utilized.

3. This will become part of our job: really knowing how the infrastructure is doing.

4. AWS collects some metrics and shows them in the Monitoring section. If the CPU is utilized more than 80%, you should add a third server to prevent page load times from increasing.

Now let us understand on;

How to check the Blogging infrastructure load balancer via resource groups?:

  1. We can find the load balancer by selecting Load Balancers under EC2 on the left to the page.
  2. By clicking the arrow icon in the Go column, you can easily jump to the details of the load balancer.
  3. Now, we are looking at the details of your load balancer.
  4. Here; the most interesting part is, “How the load balancer forwards traffic to the web servers?“.
  5. The blogging infrastructure runs on port 80, which is the default HTTP port.
  6. The load balancer accepts only HTTP connections to forward to one of the web servers that also listen on port 80.
  7. The load balancer performs a health check on the virtual servers attached.
  8. Both virtual servers are working as expected, so the load balancer routes traffic to them.    

How to check the MySQL server ?:

Details of the MySQL database which stores data for the blogging infrastructure

  1. Now; let’s look at the MySQL database. You can find the database in a resource group named wordpress.
  2. Select DB Instances under RDS at left.
  3. By clicking the arrow icon in the Go column, you can easily jump to the details of the database.
  4. Now the details of our MySQL database are shown in the screen.
  5. The benefit of using RDS is that we no longer need to worry about backups because AWS performs them automatically.
  6. Updates are performed by AWS in a custom maintenance window. Keep in mind that you can choose the right database size in terms of storage, CPU, and RAM, depending on your needs.
  7. AWS offers many different instance classes, from 1 core with 1 GB RAM up to 32 cores with 244 GB RAM.

Note: I would like to emphasize to compare the traditional [non-cloud] approach. We were using scheduler to backup the DB periodically. Some times we used to shutdown the live systems to take the backups. So, from AWS RDS services we do not need interruption to the business to take backup, RDS takes care everything. We can save the role of sysadmin/DBA while using the AWS services. This way the resources efforts and business services down time are saved.

As we planned three activities for this whole exercise as on now; we have completed the activity of “A) Set up a highly available blogging infrastructure in AWS.”

Now, we are going to work on; “B) Estimate monthly costs of the infrastructure.”

  1. As the  part of this exercise is’ cost estimation also need to be done.
  2. To analyze the cost of our blogging infrastructure, we will  use the AWS Simple Monthly Calculator.
  3. Recollect that we clicked the Cost link in the previous section to open a new browser tab.
  4. Now, switch to that browser tab, and you will see a screen as shown in the below  chart.
  5. To Estimate of our Monthly Bill, and expand the Amazon EC2 Service and Amazon RDS Service rows.

Now, Let us see and understand the below chart.

Blogging infrastructure cost calculation

Now it’s time to evaluate costs. We can see on How much does it cost?

  1. In this example, our infrastructure will cost is around $60 per month.
  2. Let us keep in mind that this is only an estimate.
  3. We are billed based on the actual usage till the end of the month.
  4. Everything is on-demand and usually billed by hours of usage or by gigabytes of usage.
  5. But what influences the usage for this infrastructure?

Let us analyze different situations and identify the costing parameters as below:

Traffic processed by the load balancer: Let us assume; Expect the costs to go down in during festival/vacation season like;  “December and the summer”. When the people are on vacation and not looking at our blogs.

Storage needed for the database: If our startup company increases the number of blogs, the database will grow, so the cost of storage will increase this way.

Number of web servers needed: A single web server is billed by hours of usage. If two web servers are not enough to handle all the traffic during the day, we may need a third server.  By default we need to keep in our AWS/EC2 setup. In that case, we will consume more hours of virtual servers.

Now we had a clear overview of the blogging infrastructure creation and its cost estimation/Analysis. Similar way you will be able to do for your AWS migration projects also.

Now; with reference to  the 3rd  step, it is time to shut down the infrastructure and complete our AWS migration evaluation exercise.

Let us recap our planned 3rd activity;

C) Finally, Delete our blogging infrastructure to save cost from free-tier account.

Now, go to the CloudFormation service in the Management Console and do the following:

  1. Select the WordPress row.
  2. Click Delete Stack, as shown in top of the screen.
  3. After you confirm the deletion of the infrastructure, it takes few minutes for AWS to delete all of the infrastructure’s dependencies.
  4. Please note; this is an efficient way to manage our infrastructure.
  5. Just as the infrastructure’s creation was automated, its deletion is also completely automated.
  6. You can create and delete infrastructure on-demand whenever you would like, and you only pay for infrastructure when you create and run it.  

<===== I copied the relevant lab practiced steps for your easy use ======>

These steps were used as on dated: 9th Sept 2018 on my free-tier account for student purpose.
The AWS might change its Screens flow or UI part time to time.
Hence from the above blog narration some detailed steps are given in the below lab practice steps for your easy use/practice.

1. Sign-in to your AWS console account from URL:
https://aws.amazon.com/

2. Login to the account.
3. Click on Services.
4. Please note we need to use Cloudformation service of AWS in this exercise.
Hence click on Cloudformation.
5. You will be shown the screen to create a new stack. Click on it. Note as mentioned in my blog it has 4 step process.
6. Now, select a sample template. Choose WordPress blog. It creates/shows the S3 template url.
7. Copy the S3 Template URL into a file for future usage.
8. Now, click on Next to go to next screen.
9. Under Specify Details columns, mention the details.
10. Please note my Infra name I want to give “wordpress”.
11. It has the predefined DB “wordpressdb”, I will keep it.
12. I can give DB Passwords, as required in the entry boxes/columns.
13. Dbuser “vskumarwp”. It has instance type t2.small.
14. Now, as you are aware we need to have the local SSH keys which we have created earlier. I have some keys I have selected one. [If you are new for this account, create the SSH keys…]
15. I need to give the range of IPs to be used for our wp servers.
I want to use 192.168.116.9/15.
16. Now, need to click on next…
Please note the above steps are required for you….

17. Let me give System as “worpress” and key as “system” as mentioned in my blog.
18. I want to skip ARN value in this exercise, due to as I mentioned in blog I would like to follow. I will not have any ARN, Hence monitoring is not mandated for me in this exercise. Then press “Next”.

19. Now, we will see the review screen as mentioned in Blog. On reveiw screen press Create button.
20. We are in creation process screen as mentioned in Blog.
CREATE COMPLETE IS DONE NOW.

21. Now let me click on my instance vskumarwp.

22. Now, go to the top navaigation bar and select the resource groups.
23. Select create resource group. You will get a new screen which has some entries and selections. Give tag key as “worpress” and press create group.
24. Next screen it shows wordpress as the resource group name.

25. Now, go to EC2 instance from the left side shown.
Now, you can see in bottom of the screen as mentioned in the blog.

26. I can see ELB by clicking on ELB option in the left panel.
Please note I have not given the ARN. Hence the Monitoring option is not selected.
Due to it might charge me.

27. You can see the cloud watch options through monitoring button in the below part of the screen.

28. Please note the security groups are attached by default.

29. Please note if I want to use this EC2 instance which is prepared for WP, I need to launch in AWS services live.
Which is going to be billed. Hence I will stop at this point.

30. The FINAL step is to delete the Instance of WP. I will go to cloudformation option.
Then it displays the current instance. I will select it and go to actions and select the DELETE STACK Option.
It prompts for ‘YES/NO’, Select Yes. It can take some time to perform deletion.

31. Once it is deleted it will comeback to the Stack creation screen.
Please note I have checked it, there are no existing instances in my current account.
We can see it as terminated instance.

32. So, this way we can create infra and delete it very easily.

33. So, let us have a final conclusion, section from blog.

34. Please call me if you need any coaching for AWS course….
THANKS FOR WATCHING MY VIDEOS/BLOGS ……..

 

Watch the below video on this blog Narration:

https://www.facebook.com/watch/?v=254567748762273

 

For the above steps a 40 mts videos has been made and hosted  on my channel. Please look into it also.

================= End of Lab practice ===============================>

 

Now, after doing all the above steps we can compare our conclusions mentioned in the beginning of this blog. I copied the same for your cross check!!

a) Creating a blogging infrastructure can be fully automated through AWS services.
b) Infrastructure can be created at any time on-demand without any up-front
commitment for how long we will use it in AWS.
c) We can pay for our infrastructure depending on how many hours we use it.
d) Infrastructure consists of several parts,
such as; virtual servers, load balancers, and databases.
e) Infrastructure can be deleted with one click without costing to us.
This process is powered by AWS automation. So it will not be billed to our free tier account after deletion.

I assume now, you are a fearless user of AWS to create the infrastructure through your free-tier account and delete and maintain the account without a cost to your CC/Account.

How a DevOps Architect role is different from A Cloud Architect ?

Many people might feel the Cloud Architect and DevOps Architect can play dual roles. As per my observation yes, many small and medium level organizations are utilizing the IT Professionals in the same manner. I wrote a blog for these roles segregation with their main Activities. I felt this might help to some of the practitioners.

With reference to my previous blog on Cloud Architect role comparison with DevOps, there were questions on DevOps architect role comparison.

https://vskumar.blog/2018/11/21/how-a-cloud-architect-is-different-from-devops-role/

Basically, A DevOps architect need to work on:

  1. Identifying the Sprint cycles for different projects.
  2. Identifying the different environments needs including the different test levels requirements.
  3. Plan/design the environment specifications to build Infrastructure As A Code [IAC] and guide the DevOps Engineers.
  4. At the same time he/she need to collaborate with the Cloud Architect to seek the permissions/approvals to utilize the cloud environment on these environmental requirements/setup.
  5. Both these architects need to measure the cost of this Infrastructure to estimate and get approval from the management.
  6. The DevOps Architect is also responsible to plan for different production deployments. He/She need to work together with the Cloud Architect to establish this setup.
  7. In the current trend the containerization is accelerating with Cloud technology. Both these architects need to keep working on these areas to reduce the Virtual Machines cost by replacing with containers. At the same time these two people need to think on converting the applications into Microservices slowly with the Agile methods. This will have easy maintenance in future and also the further cost can be reduced in view of infrastructure and the man power. And their guidelines need to submit to management as a proposal. These two people are also responsible to upgrade their teams skills on the new trends in Cloud technology.
  8. If you ask me the question who are the team members for these roles;
  9. DevOps Engineers will report to DevOps Architect.
  10. Cloud/system engineer reports to Cloud Architect.

So these architects need to manage their teams well in view of their skills augmentation and the tasks rolling as per the DevOps Speed/Velocity concepts.

What kind of IT Professionals can be converted into DevOps Architect ?

Basically, the DevOps activities are related to more on Practices and Culture. If your background is related to the below areas in the past, your profile might suit to convert by learning the above mentioned skills.

  • You might have worked on Deployment areas
  • Worked in release management
  • Worked in Development processes implementation areas.
  • You should be savvy in implementing the Agile/Scrum/Lean practices.
  • You should have worked as a Servant leadership role also. [Even as a Scrum master]. In many cases this role is responsible to mentor the teams on different practices implementation by gearing up the teams to follow DevOps Velocity.
  • You should have worked in Identifying the retrospective issues very well and implemented the improvements in different Sprint cycles.
  • He/she should be savvy in learning new technology and transform the knowledge to the teams well. This knowledge should be very simple on the tools features related areas and how they can utilize them in their setup ? How they can reduce the efforts and cost to the company with a ROI Demonstration. They need to prove it to management with a POC.
  • This person is responsible to show some ROI as Cloud Architect does it on DevOps New practices implementation.
  • The DevOps Architect reports to the DevOps Practices head or CIO or CTO. Where as the Cloud Architect reports to CIO or CTO. Depends on the size of the organization, there can be Chief Cloud architect also, where all the Cloud architects report to this position.

https://vskumar.blog/2019/02/14/what-will-be-the-size-of-cloud-market-in-it-by-2022/

Note:

The DevOps Architect need not put his fingers into low level command scripts. It is the responsibility of the DevOps Engineers.

Hope this blog clarifies for many people.

1. Vagrant/Virtual Box:How to create Virtual Machine[VM] on Windows 10?:

Vagrant-Logo                                                                                                          Oracle-VB-VM

How to create Virtual Machine[VM] on Windows 10 using Vagrant/Virtual Box.

In this exercise, we will see the following sections/topics/activities:

Let us consider the below two activities.

I. How to Install Vagrant and VirtualBox ?
II. How to Initialize our first virtual environment with Vagrant setup ?

I. How to Install Vagrant and VirtualBox ?:

Step1: Selecting the Virtual Box
Initially, we need to install the software required to manage a virtual machine
environment, which is a hypervisor as well as the Vagrant software itself.
In this activity, we will install VirtualBox to use it with Vagrant.

VirtualBox is an open source hypervisor that was initially made as the only
hypervisor and supported by Vagrant.
The VirtualBox is broadly supported by the Vagrant community.

Before we install the VirtualBox and Vagrant software, we need to obtain its latest versions.
VirtualBox can be downloaded from its project website at http://virtualbox.org.

Please note, in this exercise we are going to use for Linux installations [VMs] only. Also note, in this exercise I am using Windows10 as OS. Hence I need to select for my use the windows version under Windows hosts.

When we click on it, it downloads the file named as “VirtualBox-5.2.16-123759-Win”, as on date this is the file exists. [it might vary time to time]. You can install it on your desktop/Laptop now. 

A new installation of VirtualBox will display a welcome message in a window titled as
“Oracle VM VirtualBox Manager”.
When you have created more than one virtual machines, this dialog displays information about the machines created using VirtualBox.

Step2: Getting  Vagrant to operate the Virtual Box
Now, we need to get the Vagrant file to install.
Vagrant packages are operating system-specific and can be downloaded from the
Vagrant website at http://vagrantup.com.
Download the appropriate version  for your system [example: Windows10].
You can find, Windows 32-bit or 64-bit. In my current Laptop, I use 64 bit.
You can find the file as “vagrant_2.1.5_x86_64” to download the same.
Now install it after its download.
Vagrant setup wizard will drive you with it easy guidelines.
It installs by default into:C:\HashiCorp\Vagrant\
It takes few minutes to copy the files and install into your Desktop/Laptop.

Step3: Identify the Vagrant installation
Now, It will ask you to reboot your machine. Once you rebooted your system, please follow the below steps.

How Vagrant works?:
Let us understand; Vagrant followed the below procedure in the above Step2.
The Vagrant installer extracted and copied its files, and added the vagrant command to the executable path.
On Windows OS, this will install Vagrant to the default OS X Applications/ directory.
Also let us note; Vagrant is a command-line driven application, there are no programs
accessed from this OS.
Now, by opening a command prompt [CMD in windows] let us verify that Vagrant is working. We need to do it by executing: “vagrant version” command in CMD.

We can see the below screen output in CMD window:
=== CMD window output ====>
C:\Users\Windows>vagrant version
Installed Version: 2.1.5
Latest Version: 2.1.5

You’re running an up-to-date version of Vagrant!
===========================>

From the above output;
It is confirmed, we are ready to start using Vagrant!

Note: Please visit https://docs.vagrantup.com/v2 , to know  further the Vagrant installation guidelines.

Let us recap, What we have done is; we installed a working Vagrant environment which consists of:
a) A hypervisor application that can contain virtual machines.
b) Also let us note; Vagrant is a tool that makes managing these machines simpler and available.
c) It is important here to note that Vagrant is simply a framework to manage virtual machines.
d) It is not an application to create and host virtual machines.

II. How to Initialize our first virtual environment with Vagrant setup ?:

As mentioned in the above sections, once we have a working Vagrant environment with a hypervisor, we can initialize our first environment.
There are two ways we can  work with Vagrant to achieve this task:
a) In a new environment with a newly initialized Vagrantfile.
b) In an environment which is maintained in source control system (such as Git, SVN, etc.), which has a Vagrantfile included in a project and keeping  Vagrantfiles for different purposes of the projects.

This is a powerful  technique to manage and track changes in Vagrant environments. This kind of method can be more useful to  build the Environments easily with the concept of Infrastructure As a Code [IAC] under DevOps culture. Which is also a script driven [automated IAC] process.

But in this example, we will initialize a new environment with the basic configuration of a Vagrantfile.

Step1: Let us create a vagrantfile with  vagrant init command as below to get an ubuntu 16.04 machine with 32 bit.

I have copied my screen display with used commands for this process.

I need to have a different folder and used the below command in that folder”.

vagrant init puppetlabs/ubuntu-16.04-32-nocm

 

=== Screen output ===>

C:\>md dir vagrant-files

C:\>cd vagrant-files

C:\vagrant-files>

C:\vagrant-files>vagrant init puppetlabs/ubuntu-16.04-32-nocm
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

C:\vagrant-files>

==== We have created a vagrantfile now===>

Step2: Making Vagrant up

Before running this step please make sure you have installed the Oracle VirtualBox as mentioned in the previous section.

Now, In Command Window execute the below command.

“vagrant up”

This command might output several results; I am copying my screen output which was displayed. It takes few minutes to complete this activity.

=== Screen output for vagrant up=====>

=== End of Vagrant up process ====>

Please note with the above activity is completed, your VirtualBox window will show this VM as its status “running”. It means you are able to see this newly created VM in your “Oracle VM VirtualBox Manager”.

Step3: Checking the box

Now let us use check this VM in a Command line:

After Vagrant returns to the command line, executing the “vagrant ssh” command will open a command-line interface into the newly initialized Virtual Machine[VM].

You can see the screen output:

New release ‘18.04.1 LTS’ available.
Run ‘do-release-upgrade’ to upgrade to it.

vagrant@localhost:~$ ls
vagrant@localhost:~$

=============>

At the same time you can also go to your “Oracle VM VirtualBox Manager”, and double click on it. It will show a button “Show”, you can click on it. Opens a window with this VM.

Please note; In this exercise we have created the base box only. Hence we are not going to use this VM for our future operation.

You can see the local dir as:

== Current dir details ===>

C:\vagrant-files>dir
Volume in drive C has no label.
Volume Serial Number is 5A33-A94E

Directory of C:\vagrant-files

09/14/2018 04:14 PM <DIR> .
09/14/2018 04:14 PM <DIR> ..
09/14/2018 04:25 PM <DIR> .vagrant
09/14/2018 04:12 PM 3,108 Vagrantfile
1 File(s) 3,108 bytes
3 Dir(s) 96,101,879,808 bytes free

C:\vagrant-files>

==============>

Step4: Destroying the Virtual box

Now, we will see : a) How to exit, b)  How to Destroy this VM.

a) How to exit: We can exit it by using the command :

“control-d command, or by typing exit”

b) How to Destroy this VM: We can Destroy the virtual machine, by discarding the entire working environment. This can be done  with the “vagrant destroy” command.

When you use this command, Vagrant  will now  prompt you to make sure  that you  want to destroy the environment; type “y” to proceed with destroying the environment and deleting the VM.

=== Output for Destroy===>

C:\vagrant-files>vagrant ssh
VM must be running to open SSH connection. Run `vagrant up`
to start the virtual machine.

C:\vagrant-files>vagrant destroy
default: Are you sure you want to destroy the ‘default’ VM? [y/N]
==> default: Destroying VM and associated drives…

C:\vagrant-files>

============>

You can also check in the GUI of the  “Oracle VM VirtualBox Manager”. It will not have this VM.

In  this simple vagrant exercise in summary we have done the below steps;

  • We have downloaded and configured “Oracle VM VirtualBox Manager”.
  • We have installed Vagrant.
  • Created a Vagrant virtual box.
  • We could connect to it in a command line interface and checked the linux [ls] commands. We also cross verified it in “Oracle VM VirtualBox Manager” on its appearance as VM. 
  • Finally, we destroyed this VM.

That is all about this exercise. You can create any number of VMs like this.

=========>

Let us recap our Laptop making as Dual OS for Windows and Linux. In traditional manner we used to run behind one desktop engineer to config such dual os by paying Rs. 1,000 to Rs. 2,000 [In Indian Metro cities]. Now you can estimate how much effort and money you can save by using Cloud Technology. This VM can be copied to other Laptops/Desktops also with ORACLE Virtual Box Installation. You can do your R&D very well using this VM. You can install your applications and test/develop in Linux.

How to change your linux virtual  machines hostname and connect with ssh?

How to change your linux virtual  machines hostname and connect with ssh?

In this blog/video, I would like to demonstrate
the following by connecting hostnames with ssh:

Sometimes, we need to have hostnames differently.
When you use deployments using Ansible, etc. SCM tools
we can connect to the hostnames directly.
Now let us analyze and use the exercise as below:

By default we can find the hostname with;
$ ls -l /proc/sys/kernel/hostname
$ cat /proc/sys/kernel/hostname

We can also look into the details by using;
$hostnamectl

To change the new name use;
$hostnamectl set-hostname ‘ans-dbserver’
Step1: Checking the current  hostname.

Step2: Checking the host details in hostnamectl.

Step3: Changing the hostname.

Step4: Looking for new host details.

Step5: Reboot the machine and check its
connection with new hostname.

Step6: Now, let us try to connect to other machines
with ssh connectivity.

Step7: Making sure the renamed machine host is
being accessed by other machines also through ping.

Step8: Install openssh-server to connect through ssh in the newly named machine.

Step9: Connect through ssh from master machine to current hosts.

The attached video has the demonstration for all the above steps on Linux Virtual machines. Proved with a connectivity through ssh.

For SSH configuration please visit my blog, it has the demonstrated video also:

1. AWS:How to create and activate a new account in AWS ?

AWS Account-creation scrn

How to create and activate a new account in AWS ?:

In this blog, you will see the required steps for creating and activating your new AWS account. Once have the activated account, you can start your other lab practices as I discuss in the class timely.

The following are the main 4 steps process we need to follow:

STEP1: Creating your account. It consists of 2 steps: a) Providing a valid e-mail address and choosing a password. b) Providing your contact information and setting your preferences.

STEP2: Add a payment method Please note; you need to have a valid CC to give its details. Amazon verifies its transaction also with a tiny charge and with a credit back. If by mistaken given wrong data please note; your account registration process will not be activated. You will be intimated by mail. This way Amazon is authenticating/authorizing us for AWS usage.

STEP3: Verify your phone number. You need to Provide a phone number where you can be reached in next few minutes, while creating your account.

STEP4: Choose the AWS Support plans. Time to time the AWS plans will be published. You need to choose the plan from the currently available plans for your needs. The relevant URL is given in the detailed steps section in this blog.

As a consolidated process, we can understand from the below flow chart. Which is from the collection of AWS process charts.

AWS Account-creation flowchart

Note:

I am not copying the screens due to privacy.

Detailed steps

STEP1: Detailed steps for Creating your account.

a). You need to go to Amazon Web Services home page URL: https://aws.amazon.com/

b). Now, Choose Sign Up. Click on Create an AWS account. You can see new page with Create an AWS account. You need to enter the required details. E-mail id, Pwd, AWS Account name [you can give any name for this]. And choose continue to go to next page. Please note; The above steps are valid for the new users of AWS. If you enter your email address entered incorrectly, you might not be able to access your account or change your password in the future. So you need to be careful on your data entry part. Let us assume; if you’ve signed in to AWS recently, it might say Sign In to the Console. So you need to login into your existing Account.

c). Now in the current page, choose Professional or personal. These two areas will give equal services. Depends on your need You can choose one of the options.

d). From the above options choosed, type the requested company or personal information entries. Note; At this point, You need to go through the AWS Customer Agreement to know their policies and procedures to follow while operating.

e). Finally, you choose Create Account and Continue options in the bottom.

f). Please note; at this point you will receive an e-mail to confirm that your account is created. Now, you can sign in to your new account using the valid email address and valid password you have supplied earlier.

Please note; we have done the Step1 only, the activation process is not yet completed to use the AWS services. Still we need to follow 3 more steps.

STEP2: Add a payment method- Detailed steps:

At this point; On the Payment Information page,

a) Choose the payment method as per the payment gateway standards which is displayed.

b) Type the requested information associated with your payment method. Please make sure the address for your payment method is the same as the address you provided for your account. Note; If your billing address is different; then choose Use a new address, type the billing address for your payment method.

c) Now, choose Secure Submit.

STEP3: Verify your phone number.

Please keep a valid and handy phone number at this point.

a) On this Phone Verification page, type a phone number where can use to accept incoming phone calls.

b) Enter the code displayed in the captcha. When you’re ready to receive a call, choose Call me now option.

c) In a few moments, an automated system will call you to your given phone number. Even it might have SMS feature also, if you are outside North America region.

d) Type the provided PIN on your phone’s keypad of the AWS screen. e) After the process is complete, choose Continue.

STEP4: Choose the AWS Support plans.

a) At this point please visit the below URL: https://aws.amazon.com/premiumsupport/features/

You can select the AWS support plans from the given list.

b) After your selection of a Support plan, a confirmation page denotes that your account is being activated.

c) Please note; Accounts are usually activated within a few minutes, but the process might take up to 24 hours. This process includes the validation of Bank/CC account given there.

d) Hence keep looking for a mail on this subject from Amazon to start your AWS services usage.

Assuming everything went well, and your AWS account is activated now.  Congratulations!

We can look into next lab with reference to the class session.

28.DevOps: How to install LinuxBrew package for Ubuntu VM?

 

linuxbrew-256x256

LinuxBrew is a package-management-software.
It enables installing packages from source on top of the system’s default package management.
Some of the examples for default package management are: “apt/deb” in Debian/Ubuntu and “yum/rpm” in CentOS/RedHat.
So this is similar to them. We all might have seen this package usage more in Mac OS systems. 
In this blog, I would like to demonstrate it as below:
The relevant command screen outputs are copied at the end of this blog.

I. To install this pakage we need to follow some pre-requisites:
Pre-requisites:
1. We need to update the current ubuntu system with the below command:
$ sudo apt-get update

2. We need to upgrade the packages s below:
$ sudo apt-get upgrade -y

II. Now, we need to prepare the system for LinuxBrew package with the below commands:

 

$ sudo sudo apt-get install -y build-essential make cmake scons curl git \
ruby autoconf automake autoconf-archive \
gettext libtool flex bison \
libbz2-dev libcurl4-openssl-dev \
libexpat-dev libncurses-dev

III. Now we need to Clone LinuxBrew from github:

I need to clone LinuxBrew into a hidden directory in my home directory:
$ git clone https://github.com/Homebrew/linuxbrew.git ~/.linuxbrew

After cloning we need to update the Update environment variables as below:

We need to add LinuxBrew to the user’s environment variables.

As a part of this task, the following lines to the end of the user’s ~/.bashrc file:

== Adding lines ====>
# Until LinuxBrew is fixed, the following is required.
# See: https://github.com/Homebrew/linuxbrew/issues/47
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/lib64/pkgconfig:/usr/lib64/pkgconfig:/usr/lib/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/lib64/pkgconfig:/usr/share/pkgconfig:$PKG_CONFIG_PATH
## Setup linux brew
export LINUXBREWHOME=$HOME/.linuxbrew
export PATH=$LINUXBREWHOME/bin:$PATH
export MANPATH=$LINUXBREWHOME/man:$MANPATH
export PKG_CONFIG_PATH=$LINUXBREWHOME/lib64/pkgconfig:$LINUXBREWHOME/lib/pkgconfig:$PKG_CONFIG_PATH
export LD_LIBRARY_PATH=$LINUXBREWHOME/lib64:$LINUXBREWHOME/lib:$LD_LIBRARY_PATH
== Update .bashrc file at EOF ====>
== For the above lines =====>

IV. Now we need to test the installation:
I need to log-out and log-in again.
So, the shell should use these new settings.

To test the installation; we need to apply the below commands:

=== Testing the installation ====>
$ which brew
/home/ubuntu/.linuxbrew/bin/brew
$ echo $PKG_CONFIG_PATH
/home/ubuntu/.linuxbrew/lib64/pkgconfig:/home/ubuntu/.linuxbrew/lib/pkgconfig:/usr/local/lib/pkgconfig:/usr/local/lib64/pkgconfig:/usr/lib64/pkgconfig:/usr/lib/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/lib64/pkgconfig:/usr/share/pkgconfig:
========>
To fix common problems in LinuxBrew, those we will encounter during its usage.
We need to use 2 times the below command:
$ brew update

And we also need to Run brew doctor and fix all the warnings
$ brew doctor

V. Now let us test it for vim installation in my system:

$ sudo brew install vim

You can also try to install some other packages as you need timely.

COPIED THE EXECUTED COMMANDS SCREEN OUPUT, FYI.

27.DevOps:Working with SSH for Ansible usage

ssh

Working with SSH for Ansible usage:
With reference to my blog on Ansible installation on Ubuntu VM,  https://vskumar.blog/2018/05/08/23-devops-how-to-install-ansible-on-ubuntu-linux-vm/

in this blog, I have demonstrated on playing around with ssh among three
ubuntu Vmware Virtual machines.

To use Ansible exercises we need to follow the below pre-requisites with ssh operations.

Pre-requisites for Ansible usage:
https://help.ubuntu.com/community/SSH/OpenSSH/Keys

SSH Keys for Ansible VMs usage:
Before using Ansible we need to make sure the SSH is installed in the
VMs.
I would like to give the steps for this setup as below:

Pre-requisite Step1:
Install OpenSSH on Ubuntu.
Update the package index using the following command:
sudo apt-get update

To install the OpenSSH server application as well as the other related
packages use the command below:
sudo apt-get install openssh-server

Further, you can install the OpenSSH client application using
the following command:
sudo apt-get install openssh-client

Pre-requisite Step2:
Configure OpenSSH on Ubuntu
Before making any changes in OpenSSH configuration,
we need to know how to manage the OpenSSH service on Ubuntu VMs.

How to check ssh version?:
use the command; ssh -V

i) To start the service we can use the following command:
sudo systemctl start sshd.service

ii) To stop the service we can use:
sudo systemctl stop sshd.service

iii) To restart the service we can use:
sudo systemctl restart sshd.service

iv) To check the status of the service we can use:
sudo systemctl status sshd.service

v) If we want to enable the service on system boot we can use:
sudo systemctl enable sshd.service

vi) If we want to disable the service on system boot we can use:
sudo systemctl disable sshd.service

vii) The configuration file for the OpenSSH server application
is in the folder:/etc/ssh/sshd_config
We need to update the default port in this file.
We need to make sure to create a backup of the original configuration before
making any changes:
sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.orig

We can edit the file by using a text editor of our choice either vi or vim, etc..
The first thing we must do is to change the default SSH listening port.
Open the file and locate the line that specifies the listening port:
Port 22
Change it to your desired port number. Ex: Port 1990

Save the file and close it.
Then restart the service for the changes to take effect.

Note:
After making any changes in the OpenSSH configuration you need to restart the service
for the changes to take effect.

Pre-requisite Step3: Create an SSH key pair
Please note, during Ansible exercise or other DevOps tools, we need to connect to other VMs using SSH keys.

Let us note; the Key-based authentication uses two keys, one “public” key that anyone is allowed
to see.
And another “private” key that only the owner is allowed to see.
To securely communicate using key-based authentication, one needs to create a key pair,
securely store the private key on the computer which we want to log in from [Source machine],
and store the public key on the other Virtual Machine[Target machine] one wants to log in to.
Using key based logins with ssh is generally considered more secure than using plain password logins.

Now, let us see these steps:
1. Generating RSA Keys:
Our first step involves creating a set of RSA keys for use in authentication.
This should be done on the client.
To create our public and private SSH keys we need to use the below commands:
mkdir ~/.ssh
chmod 700 ~/.ssh
ssh-keygen -t rsa

We will be prompted for a location to save the keys, and a passphrase for the keys.
This passphrase will protect our private key while it’s stored on the hard drive:

=== Sample Output ====>
Generating public/private rsa key pair.
Enter file in which to save the key (/home/b/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/b/.ssh/id_rsa.
Your public key has been saved in /home/b/.ssh/id_rsa.pub.
======================>
Note; An SSH key passphrase is a secondary form of security.
You need to remember it while logging the remote machine.
Now, our public key is now available as .ssh/id_rsa.pub in the home directory.

The file name and pwd can be given when you follow rigid security procedures as per your project setup. Here if you avoid in giving name/pwd, it makes us easy to copy the key file to target machine.

2. Transfer Client Key to Host:
The key we need to transfer to the host is the public one.
If we can log in to a computer over SSH using a password,
we can transfer our RSA key by doing the following from our own computer:
Command format:
====>
ssh-copy-id <username>@<host>
====>
Note: The <username> and <host> should be replaced by our username
and the name of the computer we’re transferring our key to.

TIP on Port# usage:
We cannot specify a port other than the standard port 22 [unless we changed it to
another port# in the target VM]. we can work around this by issuing the
command like this: ssh-copy-id “<username>@<host> -p <port_nr>”.
If we are using the standard port 22, we can ignore this tip.

We can make sure this worked by doing the below command test:
ssh <username>@<host>

We should be prompted for the passphrase for our key:
Enter passphrase for key ‘/home/<user>/.ssh/id_rsa’:
Enter your passphrase, and provided host is configured to allow key-based logins,
we should then be logged in as usual.

 

How to remove the existing SSH from Ubuntu ?
If we have already ssh we can use the below steps to remove and
get the latest setup.

Step1: Stop SSH service before uninstalling it.
service ssh stop

Step2: Now, we need to Uninstall and remove the ssh package from the machine by using the below
apt-get command.

apt-get purge openssh-server

Now you can check its status using ssh -VM
If it is not there you should not get the version.

Please note my VMs Ips,where i will apply some exercises timely:

IP of Ans-ControlMachine:
192.168.116.132

IP of VM1:
192.168.116.134

IP of VM2:
192.168.116.135

IP of VM3:
192.168.116.133

The machine names are prompted in CLI.
I am using these four Virtual machines on Vmware environment with player as well as Workstation.

I have played around with SSH among these machines.
I have copied most of the screen outputs in this content.

Removing SSH from one Virtual machine for installating procedure testing:
I have preloaded SSH earlier.
I am purging SSH in one Virtual machine to demonstrate the exercise.
And below I have copied the screen outputs also.

5. DevOps: How to work with Docker Images

Docker-logo

In  continuation of my previous blog on “4. DevOps: How to work with Docker Containers”, in this blog I would like to give some lab practice on Docker Images.

How to pull the docker public images ?:
Docker portal will have numerous images available  under public.
Now, there is a need for us to know the usage of docker pull command, which is the defacto command to download Docker images.

Now, in this section, we will use the busybox image, one of the smallest but a very handy Docker image, to dive deep into Docker image handling:
$sudo docker pull busybox
============= Output ============>
vskumar@ubuntu:/var/tmp$ sudo docker pull busybox
Using default tag: latest
latest: Pulling from library/busybox
0ffadd58f2a6: Pull complete
Digest: sha256:bbc3a03235220b170ba48a157dd097dd1379299370e1ed99ce976df0355d24f0
Status: Downloaded newer image for busybox:latest
vskumar@ubuntu:/var/tmp$
=================>
Sometimes it might reject this request. We need to keep on trying to get it. I tried 4 times at different timings to connect to it.
Please note now, we have three images as below through all of our so far exercises:
===================>
vskumar@ubuntu:/var/log$ sudo docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
hello-world latest f2a91732366c 4 days ago 1.85kB

busybox latest 6ad733544a63 3 weeks ago 1.13MB
vskumar@ubuntu:/var/log$
===============>
Now, let us stop the docker services and check the status as below:
=================>
vskumar@ubuntu:/var/log$ sudo docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
hello-world latest f2a91732366c 4 days ago 1.85kB

vskumar@ubuntu:/var/log$ 

========================>

Now, let us reconfirm the existing docker images as below:
================>

vskumar@ubuntu:/var/log$ ^C
vskumar@ubuntu:/var/log$ sudo docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
hello-world         latest              f2a91732366c        4 days ago          1.85kB
ubuntu              latest              20c44cd7596f        7 days ago          123MB
busybox             latest              6ad733544a63        3 weeks ago         1.13MB
vskumar@ubuntu:/var/log$ 
=======================>

By default, Docker always uses the image that is tagged as latest.

Each image variant can be directly identified by qualifying it with an appropriate tag.

An image can be tag-qualified by adding a colon (:) between the tag and the repository name (<repository>:<tag>). For demonstration, we will pull the 1.24 tagged version of busybox as shown here:

Now, For lab demonstration, we will pull the 1.24 tagged version of busybox as shown here:

$ sudo docker pull busybox:1.24

Now. You can see the total output before and after executing the above command:

==============================>

vskumar@ubuntu:/var/log$ ^C

vskumar@ubuntu:/var/log$ sudo docker images

REPOSITORY TAG IMAGE ID CREATED SIZE

hello-world latest f2a91732366c 4 days ago 1.85kB

busybox 1.24 47bcc53f74dc 20 months ago 1.11MB

vskumar@ubuntu:/var/log$

==============================>

There are two busybox containers with different versions.

So, on the basis of TAG values the containers are being pulled.

How to Search Docker images:

So far we have pulled the known images from the docker-hub.

Let us identify some docker images by using a search option as below. We can search for Docker images in the Docker Hub Registry using the docker search subcommand, as shown in this example:

$ sudo docker search mysql

You can see the displayed output of mysql images from the Docker Hub Registry:

If you see the above list, The mysql image curated and hosted by Docker Inc has a 5278 star rating, which is indicated as this is the most popular mysql image and aslo as Official image to use it. For security reasons we should use the official and highly rated images only.

As we planned, in this blog we have worked with the Docker images.

At this point we can stop this session and in the next blog we can see on “How to work with interactive containers”.

On the above content I have made a video and posted  on my youtube  channel [Shanthi Kumar V] video URL: http://youtu.be/98zboBaXgoU

By seeing big cloud services vendors you and your team do not need to get confusion and get into their attraction shoes. Each vendor offer the services and their products differently. If you consider the above steps many of the issues or risks can be minimized and you will have your route map for cloud transformation along with the selection steps.

Currently; many testing or DevOps teams setup their test environments by using their existing hardware and using Virtual Machines [VMs] concepts. After certification of the product those VMs can be destroyed also.

Similarly; by having your internal cloud machines [VMs] you can automate the deployment process also by adopting into DevOps culture. Where many global organizations have achieved this activity under their regular management practices.

If you would like to know the basic cloud concepts and models please visit my cloud blogs site: https://vskumarcloudblogs.wordpress.com/

am open to offer a 2 hours online workshop [globally] to motivate your teams on the above steps, if they are on the similar activities. Please feel free to be in touch with me.
