Building large systems following DDD leads to decomposition of the domain into subdomains and creation of multiple bounded contexts in the solution architecture. While this is a good thing and reduces complexity and cognitive load of the single contexts, you will need different solutions for the inter-context application flow of your over-all system. From time to time you may find yourself puzzled with the different possibilities these approaches have to offer. Having used them for quite some time now, we stumbled upon some interesting integration questions implementing bounded contexts using Axon Framework and CQRS/ES patterns. Especially, the design of the overall architecture offers trade-offs in combining of onion, hexagonal and other styles. In this talk we demonstrate identified patterns, share some experience in integration and discuss the decisions made during the implementation of the multiple bounded context solutions using Axon Framework. In doing so, we provide examples and propose best practices we identified in our projects.
