DevOps

A set of practices that combines software development (Dev) and IT operations (Ops).

As DevOps is intended to be a cross-functional mode of working, those who practice the methodology use different sets of tools—referred to as "toolchains"—rather than a single one. These toolchains are expected to fit into one or more of the following categories, reflective of key aspects of the development and delivery process:

  • Coding: code development and review, source code management tools, code merging.
  • Building: continuous integration tools, build status.
  • Testing: continuous testing tools that provide quick and timely feedback on business risks.
  • Packaging: artifact repository, application pre-deployment staging.
  • Releasing: change management, release approvals, release automation.
  • Configuring: infrastructure configuration and management, infrastructure as code tools.
  • Monitoring: applications performance monitoring, end-user experience.
