There is no single DevOps tool to achieve all the required target steps--rather, it is called the as DevOps toolchain. The toolchain fits into one or more of the phases of software development and the delivery process, as if they work in collaboration between the Dev and Ops teams.
The phases in development and delivery could be like the following, but every organization can have their own version. Note that these phases are also helpful to establish the CI and CD pipeline.
| Phases | General Description |
| Code | Dev environment, IDE, version control |
| Build | Continuous Integration |
| Test | Automated and manual tests and related infrastructure |
| Package | Deployment packages, containers, packages repositories |
| Release | Change and release management processes |
| Configure and Provision | Infrastructure configuration and management, infrastructure as a code |
| Deploy | Deployment of packages, containers, VMS on to the infrastructure |
