One of the key features that contributes to Ansible’s popularity is its extensive ecosystem of community-contributed content, known as Ansible Galaxy. Ansible Galaxy is a hub for discovering and sharing Ansible roles, which are reusable automation components that encapsulate tasks, variables, and other Ansible functionality. These roles are created and shared by the Ansible community, allowing users to quickly find and incorporate pre-built automation into their own projects.

After we ran ad-hoc commands and created a monolith playbook, we will increase our level of automation.

Ansible roles will load variables, handlers and tasks automatically for us based on a defined directory and file structure.
