Term Kind Topic What it is
Artifact Promotion practice Artifact Management Moving one immutable build between repositories as it earns trust, rather than rebuilding it for each environment.
Automated Release Verification practice Deployment Gates A gate that compares the new version's live signals against the old one's and decides, on stated criteria, whether to continue or revert.
Configuration Drift Detection practice IaC Modules & Drift Continuously comparing declared infrastructure against what actually exists, so out-of-band change is found on a Tuesday rather than during a rebuild.
Forward Fix practice Rollback & Forward Fix Resolving an incident by shipping a correction rather than reverting, which is the right choice exactly when reverting is not actually available.
Hermetic Build practice Build Reproducibility A build whose output is a function only of its declared inputs, so the same commit cannot produce two different artifacts.
Standard Change practice Change Management vs CD A pre-authorised class of change whose risk controls are automated and evidenced, so it does not need per-instance approval.
