Production reliability includes configuration, repeatable checks, shared state, and tested recovery. A successful build is only one gate; deployed behavior must be observed, and a backup is useful only when a restore has been rehearsed.
Topics in this track
- Environment Configuration and Secret Boundaries — Validate required settings at startup and keep credentials out of client bundles.
- Continuous Integration and Release Gates — Run fast content and code checks before a candidate becomes a release.
- Horizontal Scale and Shared State — Keep case requests correct when successive calls reach different workers.
- Backup and Restore Drills — Prove a protected copy can recover a case record within a stated window.
