Idempotency, event sourcing and sagas with compensations are ways to solve your problem.

A shared database is an anti-pattern in distributed systems.

Similarly, distributed transactions (ala. DTC) is an anti-pattern.

Distributed systems aren't hard. They're just different.

Say you sell a widget. You want to update both your cash account and your inventory, and never one without the other. Which is easier to understand and more reliable: doing them atomically, or making sure you have designed in 2^n intermediate states and all the code required to complete work that should happen but hasn't yet?
