What is Azure CDN?
Azure CDN (Content Delivery Network) is a globally distributed network of edge servers that delivers static and dynamic web content closer to end users. By caching content at over 130 locations worldwide, Azure CDN reduces latency, offloads origin servers, and improves the performance of websites, APIs, and streaming services. The service supports multiple providers: Microsoft, Akamai, and Verizon.
