Hexagonal Architecture isolates the application core from external concerns by defining ports (interfaces) and adapters (inbound/outbound) to decouple business logic from technology choices.
Model your domain with ports and adapters to decouple business logic from infrastructure.

To isolate domain logic using ports and adapters, define protocol-based contracts for the core domain and use inbound and outbound adapters to connect external systems, ensuring infrastructure can be swapped without touching domain code.
Use hexagonal architecture when an application has multiple entry points like HTTP, CLI, or messaging and requires interchangeable external resources, enabling strict separation of concerns between the core domain, use cases, and adapters.
Dependency inversion improves testability by enforcing protocol-based contracts between the core domain and adapters, allowing you to easily substitute real databases or APIs with in-memory or mock adapters during testing.
Inbound adapters trigger use cases and orchestrate domain logic from entry points like HTTP or CLI, while outbound adapters connect the core domain to external systems like databases and APIs through defined ports.
Yes, you can swap databases without modifying domain code because hexagonal architecture defines outbound ports as protocol-based contracts, meaning new database adapters only need to implement the existing interface.
Applying hexagonal architecture to a small application introduces overhead through additional protocol-based contracts and adapter layers, which may overcomplicate separation of concerns if there are few entry points or interchangeable external resources.
