I keep hearing about gRPC those days; not sure if the existing trend is soaring or it is a coincidence. In any case, as I have never dug to the concept, I thought it is a good time to do so.
High-level view of gRPC gRPC is an RPC framework, created by Google. Interestingly enough, the initial “g” stands for “general (purpose)” and not for “google”.
So gRPC is an RPC framework that can be used in any kind of situation where an RPC style communication is required.
