Rethinking Hexagonal Architecture with Elegant Objects

Hexagonal architecture provides a useful foundation: business behavior should remain independent of the technologies used to expose it or persist its state. Ports define the interactions; adapters connect them to the outside world. Yet this separation does not, by itself, tell us where behavior belongs. One common implementation keeps the dependency directions of hexagonal architecture but puts most business decisions in use cases and services. Domain objects then act mainly as data structures
