what is a CDN ?


How does it work ?

Contents ( mainly static contents such as HTML files, imagery  and Javascript ) are copied to a number of server nodes spreading throughout the world. When visitors make a request to a website ( the origin server) in their browser,CDN works by directing  the optimum server(based on location and availability) to respond to the request. Contents from the optimum server will thus be transferred to the user, minimizing the distance travelled. Since a large proportion of page load time is due to retrieving the static content, it can obviously shorten the response and download time.


Main advantage of CDN

The most noticeable  advantage is a significant  increase in speed and thus ensure your website visitors to have more desirable web browsing experience.



When should you consider CDN ?

If you are hosting your website only in a particular place such as in Hong Kong, but your website is an international one where there are many visitors coming from different places around the world. They may not have the fast browsing experience as you do. If  your visitors are demanding shorter page load time, maybe it is time for you to consider using a CDN services. Many research has proven even one second delay will cause up to 7% loss in customer conversion.
