My question was rhetorical, to be honest :) point being that the only new thing, if any, with microservices is that they should be micro and you should have a lot of them.

People have been running >1 services for a long time. Sometimes calling it SOA and sometimes calling it nothing, just doing it because it made sense.

Microservices are indepently deployable modules. Thus the same principles of modular design in a monolith apply. So, yes, you're correct with the network part.
