Cloudflare CDN is a globally distributed network which delivers web pages and other web contents to a user based on the geographic location of the user. It also protects and accelerates the speed of a website. It delivers the contents to the end-users with high performance and high availability. It minimizes the distance between the visitors and the server of a website by storing the cached version of a website’s content in multiple geographic locations which is known as Points of Presence (PoP). Each PoP contains a number of caching servers for delivering contents to visitors.
