Hexagonal architecture is a model or pattern for designing software applications.. The idea behind it is to put inputs and outputs at the edges of your design.In doing so, you isolate the central logic (the core) of your application from outside concerns.Having inputs and outputs at the edge means you can swap out their handlers without changing the core code. Ports and Adapter Pattern / Hexagonal Architecture Anybody who has worked on couple of software projects with layered architecture knows how over a period of time all the projects get into the problem of excessive coupling across layers.When we start a project we all take an unsaid “oath” that we will have well separated layers where my business logic will be totally independent of my data The preceding figure shows what a hexagonal architecture might look like. The application core is represented as a hexagon, giving this architecture style its name. The hexagon shape has no meaning, however, so we might just as well draw an octagon and call it "octagonal architecture." According to legend, the hexagon was simply used instead of the common rectangle to show... 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 The hexagonal architecture is a good compromise between complexity and power, and it is also a very good way to discover the subjects we have addressed. But it is only one solution among others. For simple cases, it may be too complicated, and for complicated cases, it may be too simple. And there are other software architectures worth exploring. For example, Clean Architecture goes further in Hexagonal Architecture (aka Ports and Adapters) is one strategy to decouple the use cases from the external details. It was coined by Alistar Cockburn more than 13 years ago, and this received improvements with the Onion and Clean Architectures. Let me introduce the Hexagonal Architecture’s intent: Allow an application to equally be driven by users, programs or tests, and to be developed and Those applications seem to present Hexagonal Architecture as an over-engineered approach, where one copies the same field values from class to class just for the sake of the pattern on its own. I believe the underlying example is better suited for explaining the Hexagonal Architecture pattern. Code examples . If you are interested in the implementation of the example service, fragments of Hexagonal Architecture defines conceptual layers of code responsibility, and then points out ways to decouple code between those layers. It's helped clarify when, how and why we use interfaces (among other ideas). Hexagonal Architecture is NOT a new way to think about programming within a framework. Instead, if's a way of describing "best practices" - practices that are both old and new. I use The feedback of the Clean Architecture for .NET Applications made me feel like I needed to take a step back and introduce some concepts first, so I will present my implementation of Hexagonal Architecture to make easier to understand them completely. Unfortunately in my previous experiences in different companies, remain very common that applications are built on top of frameworks and databases. Hexagonal architecture is a model or pattern for designing software applications. The idea behind it is to put inputs and outputs at the edges of your design.
