What is DevOps? A complete guide for Beginners

Q. Why DevOps needed?

What is DevOps?

As the name suggests, it is the combination of two words ‘development’ and ‘operations.’ It encourages the teamwork between Development and Operations Team to deploy code automatically and in a continuous way.

So, this article will help you to understand the DevOps concept, tools and DevOps lifecycle.

DevOps Team

In simple words we can say, DevOps provide better communication between developers and IT operations.

Now the question is who is a DevOps engineer? The answer is very simple.

They can be developers who have the skills of development or network operations. Either sysadmin who have a passion for coding and scripting and can help in a development and deploy process.

Why it is so Popular?

Following are some advantages explained.

1. Automatic Process – It is an automatic process to deploy code on the production server. So it reduces the human error.
2. Consume Less Time – Better communication between two teams ‘developers’ and ‘Operations.’ Before DevOps, both teams work in a separate way. So this process consumes so much time to deploy code.
3. Improves speed – Because of continuous integration and continuous delivery makes the process faster.
4. Reliability – Continuous integration to test each change is safe and functional. So it is more reliable process.
5. Maintainability – It is so simple to revert the code in the previous release.
6. Security – It covers security aspects in the software delivery lifecycle. Therefore it is a secure process.

What are the DevOps Tools?

Many tools are available to automate the DevOps processes. It is the most important to choose the right tool for your application. Following some tools name are given.

Release Tools

  • Jenkins
  • TeamCity

Configuration Management Tools

  • Ansible
  • Chef
  • Puppet

Virtualization and Container Tools

  • AWS
  • Docker
  • Vagrant
  • New Relic

Code Tools

  • Git
  • Eclipse

These are the few tools to implement the DevOps operations. It should be noted that so many tools are available but you should choose the tools as per your requirement.

When to Use DevOps?

It should be used for large distributed applications. For example, large applications like eCommerce sites etc.

DevOps Lifecycle

To understand DevOps process better, it is recommended to understand it’s lifecycle. As you know, it is continuous integration between development and operations.

DevOps Lifecycle
DevOps Lifecycle

So here is given a short explanation for it’s lifecycle:

1. Development

Firstly, the development of code is done. As the name suggests, at this stage constant development of software takes place. Large development process is broken out in smaller development cycles.

2. Testing

Secondly, testers (QA Team) test the new piece of code and fixe the bugs with the help of some tools like Selenium.

3. Integration

At this stage, new functionality is integrated into the application. Continuous integration and continuous development take place at this stage.

4. Development

Afterwards, development stage comes. Continuous development takes place at this stage. It continuously checks that any changes made in the application at any time, should not affect the application.

5. Monitoring

Finally, we reached the final stage. Monitoring the application for any bug.
