A distributed network of servers known as the Azure CDN is used to cache and store material so that it may be viewed by computers all over the world. Geographical separation between a website visitor and the server that hosts the site can significantly increase latency. With the goal of reducing latency, Azure CDN servers are situated close to end users. Azure CDN allows a client seeking that content to obtain it from the location to which they have the lowest latency and maximum bandwidth connection rather than retrieving it from a single site that may be on another continent or in another hemisphere. Point-of-presence (POP) locations are the server locations that house content repositories.
By utilizing various network optimizations with CDN POPs, such as route optimization to avoid Border Gateway Protocol (BGP), Azure CDN may also speed up dynamic material that cannot be cached.
