> Microservices are advertised as a means to modularization, but it's what programming language modules are for - they are defined on source code level and can be freely used in different runtime components without network/ops/version-management headaches. When you have your module defined that way, you can think of exposing it as a microservice because this may make sense for your use case. Yes yes yes ! If your architecture and data model are funked up, then it doesn't matter how you implement them - you are screwed. On the other hand, proper modeling with separation-of-concern and well-defined interfaces will let you implement as anything you need, be it microservices or function calls inside a monolith.
