Description: Request routing is the process by which user requests are directed to the appropriate servers based on predefined rules. This mechanism is fundamental in the architecture of distributed applications and traffic management in the cloud, as it optimizes resource usage and enhances user experience. Upon receiving a request, the load balancer evaluates various factors such as the current load on servers, latency, and user geolocation to determine the most suitable server to handle the request. This not only ensures an equitable distribution of traffic but also contributes to system resilience, allowing applications to continue functioning even if one or more servers fail. Additionally, request routing can include advanced features such as SSL termination, data compression, and authentication, adding an extra layer of security and efficiency. In a distributed environment, where resources can scale dynamically, request routing becomes an essential tool to ensure that applications are fast, reliable, and capable of handling traffic spikes without degrading performance.
