Ansible
Ansible is an agentless automation tool for configuration management and orchestration. It is built around simple YAML playbooks that describe the desired state of a system.
Why It Matters
- It is easy to start with because the syntax is intentionally simple.
- It works well for orchestration tasks such as rolling updates and service restarts.
- It usually does not require an agent on the managed host.

Common Use Cases
- Configure servers from a central control node.
- Run ad hoc commands across many hosts.
- Structure automation with inventories, playbooks, roles, and templates.
Practical Notes
- Prefer idempotent tasks so repeated runs are safe.
- Keep inventories and variables separate from task logic.
- Use roles when a pattern starts repeating across playbooks.
