Hexagonal Architecture for Software Architects
Hexagonal Architecture (HA) aka Ports and Adapters Pattern, aka Onion Architecture is an architectural design pattern.
Why is there need for hexagonal architecture?
The motivation for the pattern is
- to prevent from dependencies between layers and
- to prevent contamination of layer/purpose specific code from other layers/purposes
- to improve testability and to enable automated regression testing with domain use case focussed test coverage (blog post of the pattern inventor).
