This is why I struggle with microservice architectures. It seems like there is a basic contradiction. On the one hand, it's vitally important that the microservices are carved into the correct modules otherwise you get a nightmare of operational complexity where simple functional changes require coordinated changes across multiple services. But defining the correct way modules requires a bird's-eye architectural view of the entire system, which seems contradictory to idea of self-organizing, independent teams. I can see how it works when the right way to divide things up is obvious or when you are dealing with IaaS or PaaS services, but in a complex business domain who decides how to carve things up?
