What is the function of an app router in managing requests?

The function of an app router in managing requests primarily revolves around directing those requests to the appropriate services. App routers serve as the entry point for incoming requests, determining where each request should be routed based on the defined rules and configurations. This can include considerations such as URL paths, request methods, and service availability.

By efficiently distributing requests to the correct back-end services, the app router helps optimize performance, ensure scalability, and maintain a clear separation of concerns within an application architecture. This function is crucial in microservices environments where multiple services need to work together to handle various tasks or functionalities.

Understanding this role of the app router is essential for designing robust, efficient, and maintainable web applications. While other options touch on important aspects of application security and monitoring, they do not directly relate to the specific function of routing requests, which is a core responsibility of an app router.
