Hexagonale Architektur Domain zentrierte Microservices Javaland 2019 - 19.03.2019 Christian Iwanzik @chrisIwanzik [email protected] Hexagonal Architecture, also know as the ports focuses around infrastructure concerns. Onion architecture focuses around domain concerns. Taking the example of the persistence layer, you would use an ORM in order to send and retrieve data from a data store. The ORM represents an infrastructure concern and should be placed outside domain concerns, this is called an adapter and can be later ... Hexagonal Architecture,also known as Ports and Adapter pattern is an architectural style which promotes and gives structure for achieving separation between actual application / domain logic and various technology concerns and external actors.Alistair Cockburn has a detailed article on this architecture style and below is short definition from the same article. At the very core of the hexagonal architecture lies the domain model, implemented using the building blocks of tactical DDD that we covered in the previous article. This is where the so-called business logic lives, where all the business decisions are made. This is also the most stable part of the software that hopefully will change the least (unless the business itself changes of course). The ... A hexagonal architecture simplifies deferring or changing technology decisions. You want to change to a different framework? Write a new adapter. You want to use a database, instead of storing data in files? Again, write an adapter for it. Draw a boundary around the business logic. The hexagon. Anything inside The Hexagonal architecture has several nice features. 1. It doesn't distinguish between user interfaces and interfaces to other types of actors such as servers and devices. 2. We can view a boundary object as any object that happens to implement an interface required by a controller. This interface can be viewed as a port on the boundary of the middle hexagon. This makes testing easy since we ... It also talks about the advantages of the domain-centric architecture styles of Robert C. Martin's Clean Architecture and Alistair Cockburn's Hexagonal Architecture. Then, the book dives into hands-on chapters that show you how to manifest a hexagonal architecture in actual code. You'll learn in detail about different mapping strategies between the layers of a hexagonal architecture and see ...
