In this section, we will explore how to manage projects and inventories using Ansible Tower. Ansible Tower provides a web-based interface that simplifies the management of Ansible projects and inventories, making it easier to organize, schedule, and monitor your automation tasks.

• Definition: A project in Ansible Tower is a logical collection of Ansible playbooks. Projects can be sourced from a version control system (VCS) like Git, Subversion, or Mercurial.
• Purpose: Projects help in organizing and managing playbooks, ensuring that the correct versions are used and making it easier to collaborate with team members.

• Definition: An inventory is a collection of hosts or groups of hosts that Ansible Tower manages. Inventories can be static or dynamic.
• Purpose: Inventories define the systems on which Ansible will run tasks. They can be sourced from static files or dynamically from cloud providers, CMDBs, or other sources.
