Which service should route incoming HTTP requests to the nearest regional deployment of a web app?

Azure Traffic Manager is a DNS-based traffic load balancer that distributes incoming HTTP requests to the nearest regional deployment of a web app by directing client requests to the most appropriate service endpoint based on a chosen routing method (e.g., performance, geographic, priority). Azure Load Balancer operates at Layer 4 (transport layer) and distributes traffic within a single region or virtual network, not across global regions. Azure Virtual WAN is a networking service that provides optimized and automated branch connectivity to Azure and is not designed for global HTTP request routing. Azure Front Door is a global, scalable entry-point that uses the Microsoft global edge network to create fast, secure, and widely scalable web applications, and while it offers similar functionality to Traffic Manager, Traffic Manager is specifically designed for DNS-based traffic distribution across global endpoints.
