Since its emergence in around 2009, DevOps, as a coherent set of operating principles, has made a transformative impact on how information technology is delivered and operated. In contrast with previous approaches emphasizing specialization, separation of duties, and infrequent manual change, DevOps promoted collaboration, automation, and fast feedback. DevOps has become the default approach for most software-intensive organizations and is having an increasing effect on enterprise IT operating models. It continues to evolve, deepening and broadening its reach across platforms and practices, and remains an important global movement of great interest to digital and IT leaders.
