There are many tools, projects, plugins, services adopted in the DevOps workflow. However, no one can cover all DevOps tasks. When developers move from one tool to another, they are facing the huge risk of reinvestment. How should we promote the DevOps process and make iteration more speedy? The principle of DevOps orchestration is to keep your original process working without any changes and just assemble tools, projects, plugins, services into orchestration engine. Improvements to the DevOps process can be done by gradually adding or replacing tools, projects, plugins or services for a smooth migration, and overall, DevOps needs to be promoted step by step, invasive changes are dangerous. Combo the different DevOps services, tools and plugins to implementing DevOps orchestration is very complex, and it should resolve many challenges like deliver data between jobs, or resolve environment consistency for tools or plugins.
