What is CDN (content delivery network)
CDN is a network of servers geographically located in different areas around the world. They serve as a load balancer that redirect the traffic that goes to your website to the closest Point of Presence near you. It is like a shortcut. Now your visitors will not waste time to get to the web host service you use. They will be conveniently redirected to a cached data of your site, that is milliseconds away from them. They will open the pages fast and will have a better experience.
