That's a good point, transactions are hard in the micro-service world. In my experience usually It's possible to re-design architecture to encapsulate transaction inside one micro-service. If you have transaction across multiple micro-service are they are really decoupled?

Similar problem is with doing asynchronous requests e.g. using RabbitMQ it is possible only with well designed boundaries as it's hard to control state of request if you do everything asynchronously.

Anyway micro-services is not perfect solution for everything, but even despite these problems I love working with them!
