DevOps is the talk of the town, there has been a lot of curiosity, discussions, brainstorming going in the software industry about it. There is also a lot of literature available online about DevOps, but still many fail to understand what exactly it is. Is it technology? Is it a process?
DevOps is a set of practices that combines both sides of the software world, Development (Dev) and IT operations(Ops). It aims to shorten the systems development life cycle and provide continuous delivery with high software quality.
The DevOps process is still evolving and making progress every day. As the process is still advancing and making a breakthrough, so is the role of DevOps Engineer. It is often difficult to comprehend the role as it is not confined to a single defined entity. But, to put it into the simplest terms the DevOps Engineer is a cross-functional role, the person works with the developers and Operations team to facilitate the code release in alignment with the CI/CD pipeline.
We frequently encounter this common query as “What does a DevOps engineer do?”, “What is the role of a Devops enigneer”,” What responsibilties does Devops team handle” etc.
So to answer that there is no fixed set of defined roles and resposibilities for a Devops professional, but their roles keep on changing from one organisation to another based on the requirement. However as a part of this post we have tried to cover some of the general expectations from Devops person, which again change on a need basis.
The DevOps process is an amalgamation of people of different roles coming together to work on a project as a team. So, the role requires a person who has knowledge of diverse fields. Lets have a look at the responsibilities of a DevOps Engineer:

7. A Handy Programmer
Ability to write and develop applications using coding languages. The DevOps Engineer should possess strong logical skills as the team might need assistance from development to quick fixes in the code. It is good and advisable for a Devops engineer to have familiarity with at least one of the programming languages like Python, Golang,Java etc.
The DevOps Engineer role requires the person to have a good understanding of quality assurance. The role might require to occasionally performing some QA activities involving the framework. Understanding of the QA tools is a big plus as it helps to mitigate the problems faced by the QA team.
9. Deployment strategist
