The number of servers in the network, as well as their location, varies depending on the CDN provider.
Now that you know what a CDN is, discover below some important elements for its operation.
Latency and distance
When an internet user visits a North American netherlands cell phone number list site hosted in Brazil, the site load time is longer. This happens simply because latency increases with distance.
During their journey, both the request sent by the Internet user and the response to that request pass through a series of routers.
Operating principle
To reduce this latency and ensure fast page loading, the CDN comes into play. It stores and caches a version of your static content ( HTML code , images, CSS and JavaScript files ) on mirror servers. These, in turn, are distributed across “points of presence” (PoPs) around the world.
When an internet user sends a content request, the CDN determines the server best able to respond to it. In this case, it selects the one that will guarantee the fastest processing of the request, given the internet user's location.
