title: How to deploy gRPC back end on Google App Engine (Java)
body: <p>I want to use gRPC service as a back end deployed on GAE. But there is not much related information. Maximum what I found about gRPC and recent GAE versions is Google Cloud Platform <a href="https://cloudplatform.googleblog.com/2017/06/Google-App-Engine-standard-now-supports-Java-8.html" rel="nofollow noreferrer">Blog</a>, which tells that the recent major release brings full support of gRPC.</p>
  
  <p>But I can't understand what means "full support" and how it can be actually achieved, because there are no detailed information, tutorials, samples. </p>
  
  <p>So, what the additional requirements to use gRPC within GAE (either in standard or flexible environment)?</p>
