Solution
I recommend using Azure Front Door. This service provides a single global entry point for web applications, load balancing HTTP traffic across regions. It also uses Anycast Protocol and split TCP-based anycast to direct users to the fastest and most available application backend. Therefore, it meets all the requirements specified: providing a single hostname, load balancing HTTP traffic, and routing users to the web app instance with the lowest latency.
