If you need atomicity _across services_ it's very different, hence why everyone resorts to eventual consistency and all the associated extra complexity. If there's a decent way to have true transactions that span multiple services, I've certainly never seen it.

You can get Distributed Transaction Coordinators (e.g. MSDTC on Windows), but it will make everything much slower.
