If you have ever used one then I am sure you are excited about their great results. CDN is also known as Pu Network. The acronym CDN simply means Content Delivery Network. In technologically advanced parts of the world, the average internet speed is more than 10 Mbs, and as a result, people prefer using CDN. The CDNs help users to boost things up and celebrate a remarkable speed of up to 1 Gps. It is also a noble idea to have your site powered by CDN because it makes your site to become super fast and also rank higher in search engines.

Why a CDN

More often new websites have only one source of origin. This is not a big issue when you still starting and do not have many visitors on your site. It is very important to note that as traffic increases on your website, the time taken to load your website will also increase. It is a very bad experience waiting for a website to load and thus people don’t like such websites with slow speeds. And this is the main reason for using CDN, it helps in speeding up your website content delivery by transmitting the content from the server that is closest to your visitor. This will, in turn, reduce your loading time, hence great results are achieved.
