That's definitely all it really is.

It's the classic 'thread' vs 'fork' approach. A single process with lots of threads and shared memory and all that jazz versus a bunch of relatively small processes trying to do the same job. Microservices is just forking processes over a bunch of systems and using TCP/IP for IPC. Same limitations and problems apply as before as well as the challenge of coordinating this stuff over multiple Linux instances.
