Today’s best model for delivering and maintaining IT systems. Traditionally, development and operations were two siloed organizations within IT, with the development team responsible for creating new software or making changes to existing software, and the operations team managing that software as people used it—among other things, responding to emergency outages. Unfortunately, in that model the two organizations had conflicting incentives: operations wanted systems to be stable, development wanted to deliver code and changes as quickly as possible—which causes instability. In the DevOps model, a single team is responsible for both development and operation, incentivized both to deliver quickly and maintain stability. With the help of automation and this combination of skills, conflict between these two objectives can eliminated.
