You are implementing a web app that runs in multiple regions. Each region has an Azure App Service web app provisioned. The web app address is named company1.com.
You need to route the users to the closest region when they access the web app address.
Solution: Implement Azure Front Door and configure latency based traffic-routing.
Does this solution meet the goal?
This solution meets the goal. You can use Azure Front Door to define global routing for multi-region web apps. Azure Front Door works as a global HTTP/HTTPS layer load balancer, and it is integrated with Microsoft Content Delivery Network (CDN) and DNS based global routing. Azure Front Door supports a range of traffic-routing methods for DNS based routing, such as latency based traffic-routing that routes the web traffic to the closest region.
