Configuration drift causes subtle outages when services diverge across environments. Safe configuration management treats settings as versioned artifacts with review, rollout, and rollback.
Source of Truth
Centralized config repositories with validation prevent invalid values from propagating. Environment overlays capture differences without duplication.
Rollouts and Safety Nets
Gradual rollouts and canaries reveal regressions early. Feature flags decouple deployment from activation for safer changes.
Audit and Recovery
Change logs and snapshots support rapid rollback. Access controls prevent accidental edits during incidents.
