RPC systems
Here we cover the typical traits shared by all RPC systems. There are systems that contain some of these traits, whereas mature systems provide them all:
- Since it’s RPC, the programming model is of course procedure calls: the networking aspect of the technology is abstracted away from application code, making it look almost as if it were a normal in-process function call versus an out-of-process network call.
- There is a way to define the interfaces as the names and signatures of the procedures that can be invoked along with the data types that are exchanged as arguments and return values. For RPC systems that are language-agnostic (e.g. can be used with multiple programming languages), the interface is typically defined in an Interface Definition Language, or IDL for short. IDLs can describe the shape of data and interfaces but cannot express business logic.
- The RPC systems often include code generation tools for transforming the interface descriptions into usable...
