I’m old enough to remember the days of CORBA (Orbix, Iona, BEA, anyone ??) and its IDL, the IDL compiler, stubs and other props and doodads. Ah yes, and the registry as well, where the services registered themselves, and the discovery mechanisms.

gRPC (a very Googly thing) took it all, hook line and sinker and made it URLesque

Can’t recall how the ORB overhead has been resolved in gRPCs

There is nothing analogous to the ORB in gRPC, so your complaint seems hallucinated. Callers are entirely responsible for figuring out where their services are. gRPC holds no opinions whatsoever about how your servers are named or how their lifecycles are managed. There is not a "bus".

And still I found it easier to use than gRPC.
