Hexagonal architecture is a software design principle that separates an application into distinct sections, each with a specific purpose. These sections are hexagon-shaped and can be independently changed or replaced without affecting the other sections.
Hexagonal architecture is an approach to software development that aims to create maintainable, testable and evolvable software using a layered, port-and-adapter style architecture.
What is the concept of hexagonal architecture?
Hexagonal architecture is a great way to build software systems that are testable, decoupled, flexible, and maintainable. The main focus is on the business domain, which makes it easier to spend less time on the technical aspects.
Hexagonal architecture is a term coined by Alistair Cockburn in 2006. The other name of Hexagonal architecture is Ports And Adapters architecture. This architecture divides an application into two parts namely, the inside part and the outside part. The core logic of an application is considered as the inside part. The outside part comprises of all the elements which are required for the inside part to function properly. For example, a database is required for storing data, a user interface is required for interacting with the users, etc.
What are the principles of hexagonal architecture
The hexagonal architecture is a software design principle that aims to create a maintainable, scalable, and testable software architecture. The hexagonal architecture is based on three principles and techniques:
1. Explicitly separate User-Side, Business Logic, and Server-Side Dependencies
2. Isolate the boundaries by using Ports and Adapters
3. Use message passing to communicate between components
By following these principles, the hexagonal architecture can help create a software architecture that is more maintainable, scalable, and testable.
There are several disadvantages of using adapters that should be considered when deciding whether or not to use them in a design. First, there are extra lines of code and extra classes, which adds complexity and can make the design more difficult to understand. Additionally, adapters are traditionally polymorphic, which can make calls harder to understand and debug. Finally, there is a potential performance issue as polymorphic calls can be slower than direct calls.
Why hexagons are good in architecture?
The hexagon is a versatile shape that can be used for radial organization or for flat surfaces. Its honeycomb-like grid can be built upon or broken down into a triangular grid, and its six sides make it ideal for a wide range of external surfaces. Whether you’re looking for a simple shape to build upon or a more complex one to break down, the hexagon is a great option.
Six is a very symbolic number that carries a lot of tradition and cultural heft. It is the number of creation and perfection, symbolizing divine power, majesty, wisdom, love, mercy, and justice.
Why is the hexagonal structure so strong?
The bee honeycomb is a great example of how surface tension can result in a different shape than the original shape of the units. In this case, the bees make their honeycombs with circular units, but the end result is hexagonal thanks to the surface tension. This is because the surface tension is pulling in each direction and is most mechanically stable.
There are a few potential disadvantages to using the hexagonal architecture in enterprise applications:
1. It can be more difficult to implement than more traditional architectures, and so may require more effort upfront.
2. It can be less efficient for large applications, as the extra layers of abstraction can add significant overhead.
3. It may be less intuitive for developers who are used to working with more traditional architectures.
Why are hexagons so popular
Hexagons are efficient shapes because they are symmetrical and simple. They also have the ability to tessellate, which means they can be used to tile an area. Hexagons are also supreme tessellating shapes because they can circumscribe the largest area for a given perimeter.
Design should be firm, durable, and beautiful
What are the 5 properties of a hexagon?
A regular hexagon has six equal sides and six equal angles. Its interior angle is 120° and exterior angle is 60°. It is made up of six equilateral triangles. Nine diagonals can be drawn inside a regular hexagon. All the sides opposite to each other are parallel.
Hexagons are one of the strongest shapes known to man. If you need something to hold a lot of weight, pick a hexagon. Hexagonal patterns are also prevalent in nature because of their efficiency.
Why hexagons are better than squares
Hexagons are better able to fit the curvature of the earth than squares when dealing with large areas. This is why soccer balls are constructed of hexagonal panels. Hexagons can cover more area with less perimeter, so they are more efficient for things like solar panels and beehives.
Hexagons are the most efficient packing shapes because they allow for the most amount of space to be filled with the least amount of material. This is why bee honeycombs are hexagonal in shape.
Why hexagons are better than circles?
Hexagons are often used in sampling designs because they reduce sampling bias due to edge effects. This is related to the low perimeter-to-area ratio of the shape of the hexagon. A circle has the lowest ratio but cannot tessellate to form a continuous grid.
A triangle is one of the most stable and rigid shapes used in construction because each side experiences only one force at a time. This is due to the fact that the triangle doesn’t bend. When all three sides are of equal length, the triangle is especially strong.
Final Words
The hexagonal architecture is a software architecture that separates the main parts of the application into distinct layers. The hexagonal architecture is also known as the ports and adapters architecture.
Overall, hexagonal architecture is a software design approach that aims to create maintainable, flexible, and testable code. By decoupling different parts of the system and keeping them isolated from each other, hexagonal architecture makes it easier to make changes to the code without affecting the rest of the system. This makes the system more adaptable and easier to evolve over time.
