I'm trying to think about service oriented architectures (or microservices - choose your term). Based on this.. - looking at the larger system, you are preventing scale by creating interconnects between these services - looking at the services themselves, it makes the logical boundary smaller, thus giving opportunity to find monotonicity more easily How do others think of this?
