What function does the app router perform?

The function of the app router in the context of Illumio Core is to direct requests to services. This routing capability is essential for managing application traffic and ensuring that requests are sent to the appropriate service endpoints based on defined policies. The app router plays a critical role in maintaining the efficiency and security of application interactions by effectively managing network traffic flow and ensuring that requests reach their intended destinations without unnecessary exposure to external threats.

This capability is crucial in maintaining application performance and reliability, as it not only supports load balancing among services but also helps in implementing security policies that can restrict or allow traffic based on the defined rules. Thus, its primary role revolves around the intelligent directing and management of service requests within the application architecture, making it a key component in ensuring cohesive and secure communication between various services within a network.
