What components and requirements are necessary to run and operate Ansible in configuration management automation?

The following components and requirements are necessary for launching and operating Ansible:

• Control machine: where Ansible is installed, from which commands and playbooks are run.
• Managed nodes: servers or devices managed by Ansible.
• SSH access: Ansible uses SSH to connect to managed nodes without installing agents.
• Python on managed nodes: most modules require Python to be installed on the target systems.
• Inventory file: a list of managed nodes with their addresses and groups.
• Playbooks: YAML files describing tasks and configurations for automation.

Example inventory file:

[webservers]
web1.example.com
web2.example.com

[dbservers]
db1.example.com

Ansible is run from the control machine and manages remote configuration, simplifying automation and scaling.
