An Interface Layer is a software architecture layer that provides abstraction and mediation services between system components to enable controlled interactions and data exchange.
- AKA: System Interface Layer, Integration Layer, Abstraction Interface Layer, Mediation Layer.
- Context:
- It can typically expose Interface Services through interface APIs and interface protocols.
- It can typically implement Interface Contracts defining interface method signatures and interface data formats.
- It can typically provide Interface Abstraction to hide interface implementation details from interface consumers.
- It can typically manage Interface Communication through interface message passing and interface event handling.
- It can typically enforce Interface Security via interface authentication mechanisms and interface authorization rules.
- ...
- It can often translate Interface Data Formats between interface data models and interface schemas.
- It can often handle Interface Errors through interface exception handling and interface fallback mechanisms.
- It can often optimize Interface Performance using interface caching, interface connection pooling, and interface load balancing.
- It can often support Interface Versioning through interface compatibility layers and interface migration paths.
- ...
- It can range from being a Simple Interface Layer to being a Complex Interface Layer, depending on its interface layer functionality scope.
- It can range from being a Synchronous Interface Layer to being an Asynchronous Interface Layer, depending on its interface layer communication model.
- It can range from being a Thin Interface Layer to being a Thick Interface Layer, depending on its interface layer processing responsibility.
- It can range from being a Stateless Interface Layer to being a Stateful Interface Layer, depending on its interface layer state management.
- ...
- It can integrate with Service Layers for interface business logic access.
- It can connect to Data Access Layers for interface data operations.
- It can interface with Presentation Layers for interface user interactions.
- It can communicate with External Systems through interface integration points.
- It can coordinate with Security Layers for interface access control.

- Interface Layer Implementations by architectural pattern, such as:
- Counter-Example(s):
- Direct Component Couplings, which lack interface abstraction layers.
- Monolithic Architectures, which avoid interface layer separation.
- Database Direct Accesses, which bypass interface mediation layers.
- Tight Coupling Patterns, which eliminate interface abstraction benefits.
