Cloud/Devops: How the ITSM professionals can be reused ?

Cloud/DevOps: Rebuild ITSM for Cloud/DevOps:

The Traditional ITSM professionals do not have option, except converting into Cloud/DevOps roles with the relevant tools. How this methodology works in a project level from an individual, what skills one need to be groomed: Watch the video and its description. This kind of practices a COE need to follow if the IT company has the financial capability to run the COE building at this stage instead of loosing the knowledgeable guys. Or the individuals need to open their eyes to switch their career by taking experts one on one coaching.

Rebuild Your IT career from ITSM to Infra and DevOps building with traditional exp.
I have not included the real ITSM roles. Those also can utilize into the conversion. Case to case it can be discussed. Each Organization has their own title and using them for ITSM delivery also. These role guys can work easily for implementing the IT governance in Cloud/DevOps comparatively with other roles.
This is the Stage1 Course Highlight. You will be coached for the concepts of JSON/YAML scripts towards writing the AWS Cloud service components creation. Your personal practice efforts are mandated here.
A detailed Stage2 course discussion video is there in one of the blogs. Follow the below link: https://vskumar.blog/2020/01/20/aws-devops-stage1-stage2-course-for-modern-tech-professional/
Your effort in practicing tools is required here.

Also be aware on the below points [Published in a blog also] :

I feel; For every DevOps Professional learning Infra building activity is mandatory. See the issues, what you are facing within them. Atleast one of them you are facing from your end as mentioned in the below slide/video. Then there is a gap in your implementation practice with lack of learning in a right method with best practices. So think on your actions after the below videos watching!

What IT roles can vanish with Cloud transition ? 

If you are in the below roles, in the current recession you will be targeted for pinkslip among the IT professionals as 1st exit group. What you need to do on your career replan. Please see/follow the blog/videos with patience. 

As per my observation and practice with the trending technology [Cloud], all the Cloud services vendors have inbuilt serverless computing for many services. The following roles are going to be vanished or reskilled. But if they are kept under recession staff cut, these professionals need to take care of their career.

1. DBA:–>The DBA tasks are embedded as part of these services. So the DBAs used to sit hours together in the past to perform many mundane tasks. Now these all are automated.

2. Similarly, many other tasks are related to infra roles; Network admin/Sys-Admin are also automated through Cloud services.

3. As a consolidation all these 3 roles are clubbed into one role of Cloud Engineer. This role’s major task is to automate all the Cloud setup related activities under IAC[Infrastructure As Code]. In future only the IAC will sustain to save the cost to IT by automating the cloud setup creation activity.

4. If any professional need to compete with this role means; they need to understand the Infra needs and the past roles tasks in depth. Along with the multiple Infra related architecture scenarios, with in-depth knowledge on Cloud technology. Then only they can analyze the IAC requirements clearly to write the code and test it. This is the domain analysis and design activity they need to consider apart from the Cloud technology learning.

5. We can also see the Storage engineer role. All the Cloud vendors have the Cloud Storage services. With them mundane tasks creation/maintenance is vanished. Hence this role also will not exist.

The below video has the discussion on: A) What IT Roles can vanish after migrating to Cloud? B) How the roles/tasks are being transformed to Cloud through serverless computing technology ? C) Why anybody can learn and do the past Infra roles with Cloud ? D) What all they need to learn ? E) How the organizations can demand an employee to convert into modern technology before taking a decision for a pink slip serving ?
Finally, what are the following roles and their tasks:
Traditional Infrastructure building roles:
1.Network Admin/Engineer
2.System Administrator
3.Database Administrator
4. Deployment Engineer

5. Storage Engineer — There is a separate video done for this role education:

Technical Roles:
1.Developer
2.Test Engineer/Analyst

F) Among the above which role can pickup faster the Cloud/DevOps Automation technology ?
G) Then How these roles can perform in Cloud  with faster deployment ?
H) Why and how the manpower reduction happen after Cloud implementation ?

I) Why do you need to learn from the experienced IT mentors to transform into modern technology ?

K) Some people say, they can learn by self. How much they can learn and cope-up with the current market needs on various technologies to settle in modern technology ? [refer to point#5 in this blog].

L) Why do you need to spend/invest  more money to re-settle in the modern technology ?

Note: Along with this video, there are multiple blogs I have published with Videos links to make awareness to the IT Professionals. You see those blogs from this site itself.

For further understanding please read the below text:

In the current IT World Cloud computing became regular practice for any IT Professional. Any cloud services we use, we need to know the current/traditional infrastructure setup. But every IT professional may not have that background/knowledge to understand. Because in this industry each of us played  different roles.

The Infra activities handled IT Professional only will come to know this knowledge and will have experience. But the industry needs every IT employee need to know this knowledge apart from the Cloud service provider [Ex: AWS, Azure, GC, etc..] products operations. [Eventhough, if you are a certified Solutions architect with that Cloud service provider.]

Then only whoever the professionals are certified they will be able to use these products/services and implement them under cloud setup. Hence the Infra domain knowledge or experience is mandated for every IT professional who is working for Cloud services or in that infra setup. I have been hearing during Cloud professionals recruitment the interviewers are keeping some questions on this area also. If one understand the Network domain setup then only they will be able to design the Cloud architecture. Hence more employers are worried to have this domain knowledge with the Certified and recruited Cloud professionals.

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=====>

C:\vagrant-files>vagrant up

Vagrant is currently configured to create VirtualBox synced folders with
the `SharedFoldersEnableSymlinksCreate` option enabled. If the Vagrant
guest is not trusted, you may want to disable this option. For more
information on this option, please refer to the VirtualBox manual:

https://www.virtualbox.org/manual/ch04.html#sharedfolders

This option can be disabled globally with an environment variable:

VAGRANT_DISABLE_VBOXSYMLINKCREATE=1

or on a per folder basis within the Vagrantfile:

C:\vagrant-files>

=== 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:

==== vagrant ssh ====>

C:\vagrant-files>vagrant ssh
Welcome to Ubuntu 16.04 LTS (GNU/Linux 4.4.0-21-generic i686)

* Documentation: https://help.ubuntu.com/
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.
