REL11-BP03: Automate healing on all layers

Automated healing mechanisms operate at every layer of your architecture to detect and recover from failures without human intervention. This includes infrastructure-level healing (instance replacement), platform-level healing (service restart), and application-level healing (circuit breakers, retry logic).

Implementation Steps

1. Infrastructure Layer Healing

Implement automated instance replacement, scaling, and resource provisioning.

2. Platform Layer Healing

Configure service-level healing including container restarts and service recovery.

3. Application Layer Healing

Build application-level resilience with circuit breakers, retries, and graceful degradation.

4. Data Layer Healing

Implement automated backup restoration and data consistency checks.

5. Network Layer Healing

Configure automatic network path recovery and traffic rerouting.
