RPC stands for Remote Procedure Calls, and is a form of inter-process communication where clients make a local method call that executes on a remote server. There are many implementations of RPC. Some rely on having an interface definition, for example, SOAP, Thrift of protocol buffers, but not all. This interface definition makes it easier to generate client and service stubs in various technology stacks, and therefor, it is possible to get started quickly. Many use binary for their message format, for example, Thrift and protocol buffers. Some are tied to a specific networking protocol, but others allow the use of many different types of protocols. Regardless of implementation, RPC communication looks like the following diagram. Some consuming service, be it a userface in client, or another microservice, calls a client stub that…
