The terms DevOps have been very popular in the IT world lately. It not only refers to development and operation but refers to multiple other meanings to different people. Therefore, it can be quite difficult for a newbie to understand DevOps right away and so, we have multiple concepts and working of DevOps in the following write-up to give a clear guide to DevOps.

Derivation of DevOps:

The term DevOps is derived from the two major related trends. The first one is a very detailed understanding of the value of collaboration among operations staff and development in all the phases of the development lifecycle when making and running a service along with how essential operations has become in our increasingly service-oriented world. The second major trend is agile infrastructure, also known as agile operations. This trend includes applying agile and lean approaches to operations work.

Challenges DevOps solves:

Previously, the organizations and businesses had teams to arrange and gather business requirements for a software program and writing code. Then the separate team would test the program and its working and releases the code for operations to deploy. There were further teams for networking and database setup and handling. DevOps handles these challenges in an organization and launches cross-functional teams which are capable of sharing responsibility for maintaining the system which operates the software and formulates the software to operate on that system with enhanced quality feedback and automation matters.

What are the stages of DevOps maturity?

Waterfall Development:

The developments teams would create multiple codes and then merge them before releasing them. The distinct versions of code would be so different and require many adjustments which will hence, require a lot of time for actual integration step. This method takes a lot of time for small working.

Continuous Integration:

This method allows continuous integration of the newly created code along with the main body of code, which is to release. It is an agile engineering practice while saves a lot of time. If this method is seen from a DevOps perspective, it includes proofreading your code and assembling them into a useful code and operating fundamental validation testing.

Continuous Delivery:

It is an extended part of continuous integration. When this stage is operated, additional automation and testing are added, which helps in getting the code almost ready to deploy with nearly no human efforts. This practice is involving the code base ready on continuous bases in a ready-to-deploy state.

Continuous Deployment:

It is an advanced version of continuous delivery. It’s the method of deploying all the way into production without requiring any human efforts. The utilizers of continuous delivery do not deploy untested code, while they use newly formulated code which runs via automated testing before it gets delivered to production. The code release generally only goes to a few users, and there is an automated feedback loop which continuously checks the quality and working before the code is sent any further. The continuous deployment is operated and practiced by very few companies and organizations.
