When I was designing a microservices architecture for a former employee, the justification for it was security. We needed separation of the components in the system because we were going to be handling money. It used ZeroMQ for communication, because I wanted something more lightweight and falut-resistant for message passing (in such a sensitive application, we didn't want to trust the network). Although it was of course fun to design, microservices weren't my first choice. It just made sense to us to use it in that particular scenario.
