Content Delivery Network – An Overview
CDN is a service that helps keep a copy of your website content in servers located across the world. And so, whenever users requests for your site content they will deliver with the content from the server closest to their location.
For instance, if your website is hosted on a server located in Melbourne and if some users want to access your website content from Brisbane they will be able to do it without any hassles. That's because the servers are located at nearby locations. However, in case users from a remote location, let's say, India accesses your site they'll be able to access the content but with a delay.
This is because your server takes a substantial amount of time in delivering the data to the person accessing data from India. As a result, your site will load slowly compared to the person’s browser located in the UK. But with a CDN, you can accelerate your site – whether there it get accessed by some visitor in a nearby location or a remote location of your server.
