What is CDN? Does your website need one?

The term Content Delivery Network, commonly abbreviated as CDN, is a connection of distributed networks that provide access to webpages and other Internet content to browsers depending on their geographical position, the source of the page, and respective server for content delivery. The primary objective of CDN is to avail web content to users with top availability and maximum performance. To speed up your pages, you are required to integrate CDN with your web hosting.

When visitors come to your page, their searches are guided to your website’s host server. This server is usually located in a central place. What this means is that all the visitors searching your page will have to access the same server. If your site experiences very high traffic, there is a risk of overloading the server and at times even crashing it. Because of this, utilizing CDN technology is a very wise idea to evade these issues. Because it is a network of servers positioned at different locations all over the world, CDN will copy and store your website content.

When users come to your site, the CDN technology will redirect them to the nearest server to get the static content (flash, CSS, images, and JavaScript). Having many CDN servers positioned in different areas globally will make all your pages to load faster from the visitor’s point of view. Therefore, the closer the CDN server is to the visitor’s location, the faster your website pages will load (access to content).
