No parallel in C++?!!!??

That is where EJBs and Spring come from.

The enterprise architects that created those kind of designs, were the same ones that on earlier decade were doing them with C++.

Apparently micro-services are now a thing, well on the late 90's we had Sun RPC, CORBA, DCOM. All tied together with a cluster distributed transaction management.

Sprinkled with code generation tools, based either on UML or Booch diagrams.

It was lovely, then came Java with CORBA support out of the box, RMI and GC. So they moved camps.

And yes, I am also to blame for a few CORBA objects, maybe still runing on a couple of HP-UX systems.
