The modules are basically simple scripts sent from the control unit to the required nodes, where they execute the commands defined in the playbook.

Ansible offers a variety of plugins that extend its functionality. There are also various APIs that allow you to add your own specific extensions.

Inventories of all Ansible devices, including their IP addresses, are also included. This makes it easy to select a list of nodes for which the action will be performed.

Playbooks contain instructions for each task required and are written in YAML, which is readable not only for machines but also for humans.
