DevOps is a software development methodology that accelerates the delivery of high-performance applications and services by combining and automating the work of software development (Dev) and IT operations (Ops) teams.
DevOps speeds the processes by which an idea (like a new software feature, a request for enhancement, or a bug fix) goes from development to deployment in a production environment where it can provide value to the user.
The word DevOps is a combination of the terms development and operations, meant to represent a collaborative or shared approach to the tasks performed by a company's application development and IT operations teams.
