Pattern A (Recommended)

3-State Circuit Breaker Gateway

Maintains Closed, Open, and Half-Open states across model providers to instantly reroute failed requests to hot standby providers in <150ms.

Key Technical Advantages:

  • Sub-150ms failover speed
  • Zero client code changes
  • Thundering herd protection
  • Global health telemetry
Pattern B (Alternative / Legacy)

Manual Client Retries

Client applications implement exponential backoff sleep loops that repeatedly hit degraded upstream providers until exhaustion.

Characteristics & Trade-Offs:

  • Local client control
  • Configurable retry thresholds
  • Simple to implement for single provider
