We'll explore how to build a robust, scalable platform comprised of multiple applications written in a plethora of different languages, both for the backends and frontends, using gRPC and protobuf. We'll see how gRPC, the RPC framework from Google, predicated upon protobuf (Protocol Buffers), can form the foundation for a service oriented architecture featuring message typing, stream capabilities, auto-generation of documentation, code-generation for both frontends and backends for most languages and, most importantly, fast communication using binary encoded data.
