Simple definition
Ansible automates system configuration and deployment through declarative tasks typically executed over SSH or WinRM.
Purpose and use
Ansible automates operations on managed systems, such as installing packages, producing configuration or orchestrating deployments.
How does it work?
A control node selects inventory hosts and executes modules through supported connections, commonly SSH or WinRM.
Example and verification
Before broad execution, verify host selection and test a representative scope using the intended production variables.
Points to watch
Automation is not automatically idempotent or risk-free. Behavior depends on modules, privileges and task logic.
In short
Ansible makes operations repeatable when targeting, parameters and validation are controlled.
