What Is DevOps? DevOps (a clipped compound of development and operations ) is a term used to refer to a set of practices that emphasizes the collaboration and communication of both software developers and other information-technology (IT) professionals while automating the process of software delivery and infrastructure changes. It aims at establishing a culture and environment where building, testing, and releasing software can happen rapidly, frequently, and more reliably Where Did DevOps Come From?

That process entails practicing Lean Startup with the Agile Methodology , in addition to the traditional project management focus on controlling activities. Lean startup principles measure ongoing results but then challenge those requirements as needed, as part of a build-measure-learn loop.

The Agile methodology is an approach to project management, typically ...
