title: nestjs, GRPC server and micro services architecture
body: <p>I've started a new project with nestjs with microservices, but it's my first microservices project and i don't' have enough knowledge. 
  During my documentation study, I can't find a way to use a microservice with grpc and HTTP at the same time.</p>
  
  <p>In my architecture, I have got a few microservices that have to serve REST API for the client but have also to serve grpc request for "internal" purpose, is that a right decision?</p>
