Can you highlight the differences between the hexagonal architecture and the layered architecture which each layer uses interface to communicate with others?

Sure, I can provide some special difference between them:
Purpose:
- Hexagonal: isolation of the core business logic from external component (framework, external technical, ...).
- Layer: Organizes the application into horizontal layers, each with specific responsibilities.
Dependency Direction:
- Hexagonal: Core application is at the center and independent of external systems. Adapters depend on the core through interfaces (ports).
- Layer: Dependency from higher to lower layers.
Flexibility:
- Hexagonal: easy swapping of adapters. Changes in external systems can be accommodated without modifying the core logic.
- Layer: it is also flexibility but changes may involve modifying multiple layers due to tighter coupling between layers.
Testability:
- Hexagonal: High testability, as the core application can be tested independently using mock or fake implementations of interfaces.
- Layer: Supports testability, but may have less isolation between components within the same layer, making unit testing more challenging.
