Hello, Greetings!!

Now a days most of the IT Services and Product companies are adopting DevOps based SDLC. This is rapidly growing process and everyone in IT should know about DevOps Introduction and Overview.
This article will help you understand DevOps and also help you in choosing this field if you are keen interested into it.

We will discuss here is :

• What is DevOps?
• How it works?
• Advantages of adopting the DevOps process.
• In-Demand DevOps Techs
• Market Trends and Salary in this field

What is DevOps ?

Well to clear it more DevOps is not a person, technology or organisation.

DevOps is a practice which works in Agile Methodology and responsible for Application Release and Infrastructure Management from the very initial stage of Application to its deployed stage.

The point here is that all part must be automated and well maintained with Zero Application downtime to call it a Real DevOps Process.

No matter you are using Cloud, Own Servers or shared hosting services for application deployment the process should be automated, clean, reliable and fast enough. The complete DevOps process includes all the major parts of Agile SDLC which includes Design, Development, Build, Test, Deploy and Manage.

DevOps is made of Dev and Ops , where Dev stands for Development and Ops for Operations. The Development part includes Design and Development while Operations part include testing, deployment and management of Infrastructure as well as application.

How it works?

DevOps Process works with automating all the tasks from writing a code to end release of application.
It works in the following steps :-

1.  Source Code Management
2.  Build and Testing of Code
3.  Deployment of Code

Source Code Management refers to the management of Code by versioning the code. It helps us to find out the codes latest format to its initial format along with its author and time. It is necessary to maintain it to accomplish the simplicity in release. To obtain it we use SCM Tools such as TFS, SVN and GIT.

Build and Testing of Code is the middle process of an application release, in this step all code are combined into packages and built together along with all its required library and dependencies, once the build is completed the unit testing is performed

Deployment of Code includes putting the built code on internet via help of Automation Tools and Scripts.

Advantages of DevOps

DevOps Team is a group of enthusiastic and cross platform worker members. They perform a very important role in the Continuous Integration and Continuous Deployment of Application which results in :

1. Faster Delivery
2. Continuous Integration of complete application development life cycle
3. Faster bug fixing
4. More fail over and roll back strategies.
5. Higher SLA(s)
6. An Application with less bugs and zero downtime.

Tools and Techs

Following are in-demand basic techs for DevOps role:-

• Jenkins (to automate all the tasks from building and testing to deployment)
• Ansible, Terraform, Python (to create Infrastructure with help of coding skills)
• Maven, MSBuild (to Build the code)
• Selenium and Junit (for testing and building test cases)
• Docker and Kubernetes (for containerisation of Application and eliminating the need of higher server resources)
• Grafana and Prometheus (for monitoring Infrastructure and Applications)
• Cloud (AWS/GCP/Azure)

Regardless of Open Source there are more Paid tools which are  Redgate, VSTS, MS Build, Bamboo and many more.

You don’t need to be master of any programming language for performing DevOps Operations but to understand your application and its dependencies you must know the basic of programming language in which you application is built.

Python is base scripting language you have to know about while working in DevOps process in Linux and for Windows it can be accomplished with Powershell.

Market Trends and Salaries of DevOps Engineer

Currently as technologies are growing rapidly every company wants to grow their application to bug less and changes to be made more frequently hence they are open for DevOps Engineers.

A DevOps Engineer is not just about using tools and scripts and automating all the task, it is about how much faster and smarter you can do you work? you must have soft skills as well to become a good DevOps Engineer.
