Serverschichten

Serverschichten, also known as server layers or server tiers, refer to the architectural design of a server system, dividing its functionality into distinct, logical layers. This approach promotes modularity, maintainability, and scalability. A common model is the three-tier architecture, which separates presentation, application logic, and data storage into independent layers. The presentation layer, typically the user interface, handles user interaction. The application layer, or business logic layer, processes user requests and performs calculations. The data layer is responsible for storing and retrieving data, often utilizing a database server. Other variations exist, such as two-tier (client-server) or multi-tier architectures, depending on the complexity and specific requirements of the application. Each layer can be developed, deployed, and scaled independently, allowing for greater flexibility and efficiency in server management. This separation of concerns makes it easier to update or replace individual components without affecting the entire system, contributing to a robust and adaptable server infrastructure.
