What is Azure Front Door?

Whether you’re delivering content and files or building global apps and APIs, Azure Front Door can help you deliver higher availability, lower latency, greater scale, and more secure experiences to your users wherever they are.

Azure Front Door is Microsoft’s modern cloud Content Delivery Network (CDN) that provides fast, reliable, and secure access between your users and your applications’ static and dynamic web content across the globe. Azure Front Door delivers your content using Microsoft’s global edge network with hundreds of global and local points of presence (PoPs) distributed around the world close to both your enterprise and consumer end users.

For web workloads, we highly recommend utilizing Azure DDoS protection and a web application firewall to safeguard against emerging DDoS attacks. Another option is to employ Azure Front Door along with a web application firewall. Azure Front Door offers platform-level protection against network-level DDoS attacks.
