Envoy Proxy

Envoy Proxy Rate Limit Service API

The Envoy Rate Limit Service (RLS) is a gRPC-based API that allows Envoy to delegate rate limiting decisions to an external service. When a request matches a configured rate limit rule, Envoy calls the RLS to check whether the request should be allowed or throttled based on descriptors extracted from the request context.
