Ansible Concept and Architecture
Controlnode – Ansible is installed and run from the controlnode and will contain copies of your project file including ansible playbooks. It can be a workstation or a dedicated server in the environment.
Managed Hosts – these are listed servers or nodes in the inventory – defined as static or via dynamic inventory scripts – on which Ansible commands or playbook tasks need to be executed.
Playbook – Plays are ordered set of tasks to execute against host selections from your inventory. A playbook is a file containing one or more plays.
Tasks – Task run a module with arguments to accomplish the required state or action.
Tasks → Plays → Playbook
