When managing remote systems with Ansible, tasks are generally executed on target hosts over SSH. However, there are scenarios where you might want to execute certain tasks on the local machine (the control node) instead of the remote hosts. Ansible provides built-in mechanisms for delegating tasks to the local host or other specific hosts while running playbooks remotely.
