gRPC Best Practice @ CoreOSFest 2017

https://coreosfest2017.sched.com/event/AWYc/best-practices-for-go-grpc-services-doug-fawley-google

Just small note for me. Hope the slide will be opened.

• API design
  • Idmpotency
    • It should be safe to retry an RPC without knowing whether it was processed
• Example

# The upstream server doesn't need a prefix! no need for wss:// or http:// because nginx will upgrade to http1.1 in the config below
upstream yeomanserver {
        server localhost:3000;
}


server {
        listen  443;
        server_name legionofevil.org;
