Who is a DevOps Engineer?

DevOps is a combination of the words Dev and Ops; wherein ‘Dev’ is short form for development while ‘Ops’ is short form of Operations. DevOps can be defined as a software development technique that narrows down the gap between developers and IT professionals in layman’s language. Software development is quite rapid in modern times, customers are constantly looking for quick solutions with greater flexibility. DevOps technique allows tech companies to release applications with small features very quickly. DevOps is a robust feature-laden methodology that lets organizations adapt to new requirements with ease and reduce lead time between fixes. 

A DevOps Engineer has an in-depth understanding of the Software Development Lifecycle and has good grip on different automation tools required for developing CI/CD (CI – Continuous Integration and CD – Continuous Deployment) pipelines. DevOps engineers primarily work with application developers and IT experts to ensure seamless code releases. One can work as a DevOps engineer if they happen to work as an application developer while interested in deployment and network operations or if they happen to work as a system administrator while interested in scripting and coding, transitioning themselves into development for improving the planning of testing and deployment. 

Roles and Responsibilities of a DevOps Engineer
