DevOps is a software engineering method that combines software development and information technology operations into a single continuous, collaborative workflow, aiming to shorten the cycle from writing code to deploying it reliably in production by breaking down the traditional separation between developers who build software and operations staff who run it. Practices commonly associated with DevOps include continuous integration and continuous delivery pipelines that automatically build, test and deploy code changes, infrastructure managed as code, and shared monitoring so both development and operations teams see how software behaves in production. The term and the movement it describes emerged around 2009, growing out of the agile software development community's push to extend iterative, collaborative practices beyond coding into deployment and operations.
Facts
Core PrincipleSoftware development and information technology operations are integrated and automated together, so that development time is shortened and the development life cycle improves. 1 FAQs
What is DevSecOps and how does it relate to DevOps?
DevSecOps is DevOps in which security is the focus of everyone on the team.
DevSecOps is the name sometimes given to a DevOps team in which security is the concern of everyone on the team, rather than a separate review at the end. In some DevOps models, quality assurance and security teams become more tightly integrated with development and operations throughout the application lifecycle, so security is built into the same continuous workflow instead of being handled by a separate group.
Does DevOps mean merging developers and operations staff into one team?
Sometimes. Merging is one DevOps model, but the core change is close collaboration.
Not always. Under a DevOps model the two teams are no longer siloed, and sometimes they are merged into a single team whose engineers work across the entire application lifecycle, from development and test to deployment to operations. Either way, developers and operations teams collaborate closely, share many responsibilities and combine their workflows.
