Application operations
CoreApp Service deployment slots and backup
Release swap boundaries and point-in-time application recovery.
Key points
- Slots provide live deployment environments that can warm and swap traffic.
- Slot settings can remain attached to a named environment during swaps.
- Backups retain supported app content and configuration for later restore.
Best-known use cases
- Validate a release before production traffic.
- Restore an app from a scheduled recovery point.
What candidates often confuse it with
- Deployment slot vs backup: release promotion and rollback path vs historical recovery copy.
- Swap vs restore: exchange active slot state vs recover retained application state.
Key takeaway
Use slots for release safety and backups for point-in-time recovery; neither replaces the other.
