Introduction To DevOps

DevOps integrates developers and operations team to improve collaboration and productivity.

According to the DevOps culture, a single group of Engineers (developers, system admins, QA’s. Testers etc turned into DevOps Engineers) has end to end responsibility of the Application (Software) right from gathering the requirement to development, to testing, to infrastructure deployment, to application deployment and finally monitoring & gathering feedback from the end users, then again implementing the changes.

This is a never ending cycle and the logo of DevOps makes perfect sense to me. Just look at the above diagram – What could have been a better symbol than infinity to symbolize DevOps?

Now let us see how DevOps takes care of the challenges faced by Development and Operations. Below table describes how DevOps addresses Dev Challenges.

DevOps Tutorial Table 1 – Above table states how DevOps solves Dev Challenges

Going further, below table describes how DevOps addresses Ops Challenges.

However, you would still be wondering, how to implement DevOps. To expedite and actualize DevOps process apart from culturally accepting it, one also needs various DevOps tools like Puppet, Jenkins, GIT, Chef, Docker, Selenium, AWS etc to achieve automation at various stages which helps in achieving Continuous Development, Continuous Integration, Continuous Testing, Continuous Deployment, Continuous Monitoring to deliver a quality software to the customer at a very fast pace.

Now take a look at the below DevOps diagram with various DevOps Tools closely and try to decode it.

These tools has been categorized into various stages of DevOps. Hence it is important that I first tell you about DevOps stages and then talk more about DevOps Tools.

DevOps Lifecycle can be broadly broken down into the below DevOps Stages:

Continuous Development

Continuous Integration

Continuous Testing

Continuous Monitoring

Virtualization and Containerization

These stages are the building blocks to achieve DevOps as a whole
