I’m very intrigued by this comment. It probably captures the thing that has held me back from microservices. Can you explain how one can break up a monolith without keeping the interdepencies?

Say you have some unit of work A within a monolith, and it is used by service B, C, D also in the monolith.

You can carve out A as a microservice with a clean general interface, and write an adapter layer to translate calls from your old messy interface to your new one, and B, C, D call that. Then start refactoring B, C, D one by one depending on your priorities.

That way new service X that needs to use A, can directly start using the clean general API even if B, C, D are not refactored yet.
