The first play includes the creation of the devops group and user, and installation of the htop package. Since we have three hosts in our inventory, we see one line per host being printed, which indicates whether there was a change in the state of the entity being managed. Ansible then moves to the next play. Finally, Ansible prints the summary of the playbook run in the "PLAY RECAP" section. It indicates how many modifications were made, if any of the hosts were unreachable, or execution failed on any of the systems.
