An infrastructure audit found that the Compose demo exposes one driver-location-api instance directly on host port 8000. The event-driven architecture has no local Layer-7 gateway, multi-replica API routing, or unhealthy-replica resilience demonstration.
Tracking issue: #17 — add a gateway load balancer for horizontally scaled APIs.
This record does not claim a load balancer, horizontal scaling, resilience test, or benchmark result has been implemented. The issue defines the required implementation and validation scope.
