What is a CDN? A CDN or Content Delivery Network is an “intelligent” global network dedicated to the distribution of web Turkmenistan Email List content . It is an infrastructure made up of several networked servers located in different countries. These servers store content replicated from an origin server. To minimize the distance between each visitor and the server that hosts a website, each server in the WEB CDN infrastructure stores a cached version of the website content in multiple geographic locations.

CDN network infrastructure content Delivery Network infrastructure The main objective of a WEB CDN infrastructure is to deliver web pages with optimal loading time for the visitor. The operating principle of a CDN server therefore consists in making the content of a website available in several geographical locations at the same time (points of presence or PoP) . Each PoP is made up of multiple caching servers responsible for serving content to nearby visitors. A CDN infrastructure allows you to offer efficient global coverage to your visitors . For example, when the Internet user located in Montreal accesses your website hosted in Paris, a POP located in Canada delivers your web page.
