DevOps toolchain

As DevOps is intended to be a cross-functional mode of working, rather than a single DevOps tool there are sets (or “toolchains“) of multiple tools. Such DevOps tools are expected to fit into one or more of these categories, reflective of key aspects of the development and delivery process

1. Code — code development and review, source code management tools, code merging
2. Build — continuous integration tools, build status
3. Test — continuous testing tools that provide feedback on business risks
4. Package — artifact repository, application pre-deployment staging
5. Release — change management, release approvals, release automation
6. Configure — infrastructure configuration and management, Infrastructure as Codetools
7. Monitor — applications performance monitoring, end–user experience

Some categories are more essential in a DevOps toolchain than others; especially continuous integration (e.g. Jenkins) and infrastructure as code (e.g. Puppet).
