once again, the question is about how to write a system that can be more easily split into microservices later. I would separate business logic into a single service and have all other modules call that using a standard protocol like REST or thrift or something. The issue is that if that logic is being executed all over the system already, it's going to be difficult to break it into a separate service that doesn't do that
