In a nutshell

• A Control Node executes tasks, defined in playbooks on Managed Nodes over SSH or API's
• Control Node: This can be any linux based host (or windows with wsl) where ansible is installed and is connected to the same network as the Managed Nodes
• Managed Node: Any device that should be managed or setup
• playbook.yml: A yml file that contains the involved hosts, process and tasks that should be done
• inventory.yml: A yml file that contains all hosts, grouped in sections if needed (e.g. different branches, locations, device/os types)
