Very interesting read! I like that GOOG is pushing gRPC more on their own services. I've been a gRPC user since Sep/Oct last year, and it's made developing for Android, Node.js, JVM, Python more pleasant from a networking perspective. The ease of just moving logic from Node.js to a Java gRPC server, and then redirecting the HTTP2 proxy to the right place, has been awesome.

I've started teaching some people in the team how to use gRPC, and we're def going to be using it where permissible on client projects.
