This article covers the essential DevOps tools that every proficient DevOps engineer should be familiar with. The tools are divided into eight different sessions, but mastering all of them at once is not mandatory. Source control management (SCM) tools are essential in DevOps for managing the source code of software applications and enabling collaboration among developers. The two most popular SCM tools used in DevOps are Git and Subversion. Additionally, other tools such as automation tools, configuration management tools, containerization tools, monitoring tools, and log aggregation tools are also necessary for a successful DevOps implementation. The choice of tools to use depends on the organization’s preferences.
