APIkerroksia, often translated as API layers, refers to the conceptual or structural organization of different interfaces within a software system that interact with each other. These layers help in managing complexity, promoting modularity, and facilitating independent development and deployment of different parts of an application.

Typically, an API layer serves as an abstraction. It hides the intricate details of a lower-level service or component and exposes a simpler, more manageable interface to higher-level components. This separation of concerns means that changes within one layer, as long as the API contract remains the same, do not necessitate modifications in other layers.

Common examples of API layers include presentation layers, business logic layers, and data access layers. The presentation layer might expose APIs for user interfaces to interact with, while the business logic layer handles core application functionality and exposes its own APIs. The data access layer, in turn, manages interactions with the underlying data storage, again through a defined API.

The use of API layers is a fundamental practice in software architecture, particularly in large-scale systems and microservices. It allows for a more organized and scalable development process, enabling teams to work on different layers concurrently and independently. This architectural pattern contributes to maintainability, testability, and the overall robustness of software applications.
