Overview
Configuration Management (CM) ensures that all systems (servers, containers, network devices) are configured correctly and consistently. It prevents 'configuration drift,' where systems slowly become different from each other over time due to manual changes.
Key Goals
- Consistency: Every environment (dev, test, prod) is configured identically.
- Auditability: Every change to a system's configuration is tracked and recorded.
- Automation: Eliminates manual, error-prone configuration tasks.
