how cdn works

Everyone hates slow websites! In fact, recent surveys found that nearly half of web surfers expect a web page to load in 2 seconds or less, and they are likely to abandon a website that takes more than 3 seconds to load. If you want your website to load faster, you should definitely consider using a CDN.

Instead of serving content from a single shared hosting account, most CDNs have dozens of servers around the world that replicate static content (JavaScripts, CSS, images, etc.). Roughly speaking, a CDN is an interconnected series of servers that cache, store, and distribute your content to many end-users simultaneously based on their proximity. In other words, content delivery networks serve web pages depending on where the user is located.

For example, if a user is trying to reach your website from Asia, a cached copy of your original content will be served from the closest CDN server in Asia. These servers are called edge servers, as they are closest to the end-user.
