With different methodologies, architectures and more than 2,500 different programming languages , choosing the right components and keeping applications clean and functional, according to the needs of each project, is a challenge for companies, as well as for programmers and engineers. However, the hexagonal software development architecture is standing out in recent years, thanks to the flexibility it offers, when it comes to ensuring the quality and scalability of the software, maintaining independence between the business logic and the technical details of the system. . Do you want to know what hexagonal architecture is and how it works? In this article, we offer you all the keys. CTA What is hexagonal architecture? The hexagonal architecture , also known as the “port and adapter pattern”, is a software development methodology created by Alistair Cockburn in 2005. It is a proposal that advocates maintaining independence between the different components of a computer program, ensuring its easy interconnectivity through ports and adapters.
In this way, its objective is to avoid some of the structural errors that usually occur in the development of object-oriented software. For example, it is common for different modules to be too dependent on each other, something that increases complexity and reduces flexibility when making changes or exchanging components. Likewise, the hexagonal architecture also favors Clean Code programming by explicitly keeping the user interface, business logic, and server Europe Mobile Number List separate. This makes it easy to automate testing, maintenance, and bug fixes. In this architectural approach, software components are represented in the shape of a hexagon. In the center is the core of the application, which is surrounded by the different modules. Furthermore, enough space is left between them to represent the connections between the different components. Components of hexagonal architecture To understand how the hexagonal software architecture works, it is necessary to identify in detail the components on which this development methodology is based.
In this sense, we can differentiate between domain, ports, adapters and infrastructure. Domain (core) The domain or core is located in the central layer of the hexagon and contains all the business logic of the application, as well as the main business rules, constraints, behavior or data model. The domain must function independently of the other layers. Ports Ports act as an entry point and allow interaction between the application core and the adapters. In this sense, they are responsible for transmitting information and making the adapters work. There can be as many ports as necessary. We can imagine them as a USB port to which it is possible to connect different types of devices. Adapters Adapters allow communication between users and the core, using ports as intermediaries. They can be replaced without affecting the core, since they will continue to be able to exchange information thanks to the ports. The adapters are located in the “infrastructure” layer, which is on the outside of the hexagon, contains all the input and output elements of the application and allows the latter to communicate with external services. architecture-hexagonal Advantages and disadvantages of hexagonal architecture As you can see, the hexagonal architecture has different mechanisms that allow the software to be programmed and maintained flexibly.
