"A portmanteau of "development" and "operations," devops emerged as a way of bringing together two previously separate groups responsible for the building and deploying of software. In the old world, developers (devs) typically wrote code before throwing it over to the system administrators (operations, or ops) to deploy and integrate that code. But as the industry shifted towards agile development and cloud-native computing, many organizations reoriented around modern, cloud-native practices in the pursuit of faster, better releases."
"Devops was born at cloud-native companies like Facebook, Netflix, Spotify, and Amazon; but it's become one of the defining technology industry trends of the past decade, primarily because it bridges so many of the changes that have shaped modern software development. As agile development and cloud-native computing have become ubiquitous, devops has enabled the entire industry to speed up its software development cycles."
Devops combines development and operations to remove the handoff friction that slowed traditional software delivery. Developers and operators collaborate to enable continuous integration and continuous delivery, replacing long "big bang" releases with rapid, incremental updates. Devops originated at cloud-native companies and spread because it aligns with agile and cloud-native trends. The practice accelerates software development cycles and has been widely adopted across enterprises that depend on software, including banks, airlines, and retailers. Devops also spurred the creation of related "ops" practices and requires a cross-functional mindset shift between development and operations teams.
