Configuration
The specific arrangement of system elements and their settings. In IT, it refers to the detailed parameters (hardware, software, network) that define how a system functions.
Impact
Configuration drift—where the actual state of a system slowly diverges from its intended state—is a leading cause of instability and security vulnerabilities.
Weinto take
Configuration is Code. Manual configuration via a GUI (ClickOps) is strictly forbidden in a mature engineering organization. All configuration must be versioned in Git, peer-reviewed, and applied automatically to ensure consistency and reproducibility.
