For gRPC there is Envoy, but I have not used it so I can’t give you more info on it. However, I think the point in the article is that you need to have well defined schemas for inter-service messaging. Something like protobuf or thrift or flatbuffers. Whether you layer gRPC on top of that is a separate concern. For example I have used Protobufs extensively at work but never gRPC, since we mostly have point-to-point connections. We checked in the message schemas into their own repo and all users across the company pull from it. We have Python and C++ codebases sharing the same schemas, it’s quite wonderful.
