Event-driven microservices: what can go wrong?
In the classic paper Data on the Outside versus Data on the Inside Pat Helland argued that data within a service boundary should be treated differently than data residing outside of it.
Here, I shall argue that the same applies to messages. Inside a service boundary messages are tightly coupled to the corresponding data manipulations. Outside, the world is much more hostile and less predictable and communication strategy needs to be adequate.
