RPC Implementations

GRPC (http://www.grpc.io/) is Google's RPC implementation for Protocol Buffers. There are other third-party RPC implementations as well. Some of these actually work with Protocol Buffers service definitions (defined using the service keyword in .proto files) while others just use Protocol Buffers message objects.
