I still use CORBA with huge success. For example, it is a backbone of several commercial systems that connect vending units in different regions and even countries.

For what it's worth, CORBA is hard to use from languages without a proper reflection. But with something like Java or .NET - it's a breeze.

And before you start asking questions why - no, REST or gRPC do not cut it. They are too primitive and come with poorly defined semantics. Their HTTP/1.1 transport is rudimental, though HTTP/2.0 made it better by allowing multiplex streams with an elusive possibility of a proper bidirectional communication. But CORBA already had all that, and more, since 2005! And I use it to the fullest extent in the distributed systems my company designs.

I'm fascinated by this! Do you have any favorite books or articles that turned you on to CORBA?

gRPC is tightly coupled with HTTP/2 so the way you’re grouping it with REST doesn’t really make sense.

gRPC-esque protocols started to appear as protobuf serialization (for procedure calls) on top of a REST endpoint (for tunneling). It officially became gRPC and "coupled" with HTTP/2 much later.
