Designing and implementing an Azure Front Door load balancer service

Azure Front Door is a service that delivers applications and caches content using a network of globally distributed edge nodes. It offers capabilities such as global load balancing, dynamic and static content acceleration, and web application protection at the global edge for web applications and APIs. Unlike the regional Application Gateway, Front Door is a global service that can serve requests and content for endpoints distributed across multiple Azure regions or even those outside of Azure.

In Figure 9.37, the Front Door service receives client requests from end users through a nearby point of presence (or edge location) using an anycast public IP address. It then leverages Microsoft’s high-throughput backbone network to accelerate delivery to the backend application instead of routing traffic entirely over the public internet. Azure Front Door has over 150 points of presence (PoP) distributed globally...
