Recently, I've been looking for a good alternative to Traefik as Reverse Proxy for gRPC services. Traefik has great support for gRPC and other common features, but Envoy comes with Protobuf-backed configuration and even greater support for gRPC services. In the article, I want to show how you can make Envoy use your custom authorization logic before redirecting (or not) the request to other services.
