Go Micro is a pluggable RPC based microservice library which provides the fundamental building blocks for writing distributed applications. It is part of the [Micro](https://github.com/micro/micro) toolkit. It supports Proto-RPC and JSON-RPC as the request/response protocol out of the box and defaults to Consul for discovery.
