Ansible Tower

Ansible Tower is like Ansible at a more enterprise level. It is a web-based solution for managing your organization with an easy user interface that provides a dashboard with all of the state summaries of all the hosts. And allows quick deployments, and monitors all configurations.

The tower allows us to share the SSH credentials without exposing them, logs all the jobs, manage inventories graphically, and syncs them with a wide variety of cloud providers.

Previously, Ansible Tower called the AWX project, is the fix to this problem. Especially those that render better as graphical rather than text-based output, such as real-time node monitoring.
