Benefits and Drawback of Hexagonal Architecture

This section will cover the benefits and drawbacks that people may come across when implementing hexagonal architecture. These will lead to better trade-offs, resulting in the best outcome for companies and projects.

Benefits of hexagonal architecture

• Well-defined dependency structure, resulting in a clear domain model implementation.
• Promotes being focused on domain logic, which is a good match with a Domain Driven Design context.
• Defines clearly what to put where in the code. That definition is important to maintain code as clean as possible. Helps in having faster, more focused automated tests for domain logic, and mocking databases, and other external services.
