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 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.

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

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.
