You can invoke a single module with a task, or invoke several different modules in a playbook. Starting in Ansible 2.10, modules are grouped in collections. For an idea of how many collections Ansible includes, take a look at the Collection Index. Tasks The units of action in Ansible. You can execute a single task once with an ad-hoc command.
