36. What are the main principles of DevOps?
DevOps is different from Technical Operations. It has following main principles:
I. Incremental : In DevOps we aim to incrementally release software to production. We do releases to
production more often than Waterfall approach of one large release.
II. Automated : To enable use to make releases more often, we automate the operations from Code Check in to
deployment in Production.
III. Collaborative : DevOps is not only responsibility of Operations team. It is a collaborative effort of Dev, QA,
Release and DevOps teams.
IV. Iterative : DevOps is based on Iterative principle of using a process that is repeatable. But with each iteration
we aim to make the process more efficient and better.
V. Self-Service : In DevOps, we automate things and give self-service options to other teams so that they are
empowered to deliver the work in their domain.
