How does Rails handle large-scale API gateway orchestration and edge routing?

Rails integrates with API gateways that handle routing, authentication, rate limiting, and edge traffic management.

API gateways act as the entry point for all client requests. They handle SSL termination, authentication, request routing, and rate limiting. Rails services sit behind the gateway and focus on business logic. At scale, edge routing ensures traffic is directed to the nearest region or healthy service instance using geo-routing or latency-based routing.
