Ansible Tower is a web-based GUI developed by Ansible. Ansible Tower provides you with an easy-to-use dashboard to manage your nodes and role-based authentication to control access to your Ansible Tower dashboard. You can use LDAP or Active Directory to manage your users with Ansible Tower. Apart from the dashboard and role-based authentication, Ansible Tower also provides a built-in REST API, job scheduling, graphical inventory management, job status updates, and so on.

Ansible Tower is not freely available; you need to pay, depending on the number of nodes you want to manage. At the time of writing of this book, Ansible provided a free copy of Ansible Tower for 10 nodes.
