I’m very new to CQRS and domain events. I have just finished Vaughn Vernon’s Implementing Domain-Driven Design and I find the concept of using domain events to integrate several bounded contexts very appealing.
However, it seems a service bus is needed for this integration to work. I’m not sure how Axon relates to a service bus. I’ve found tools like Mule ESB and Apache Camel which claim to be a service bus, but Axon defines itself as a CQRS and ES framework.
Does that mean that I still need a service bus to be used with Axon? or is Axon built on a custom made service bus? or does it take a whole other approach?
Note: I’m not looking for anything related to Event Sourcing, just a way to integrate several services hosted on different servers using domain events.
