What is a Content Delivery Network (CDN)?
A Content Delivery Network, or CDN is a web service for content delivery. The goal is to give your websites visitor a fast and easy user experience. This is done by caching parts of the website as close as possible to their location. It is an easy way to distribute content to end users with low latency and high data transfer speeds. All types of content (images, videos or java scripts) can be placed on the original source server and will automatically be copied to the closest location, when visitors request them.
The source of your website will always be where it is hosted, let´s say in the US. Without a CDN, a visitor from China will be served from your US server. You can imagine it will be much faster if the files come from a local China server which has a copy of your webistes images.
How does it work? You have to determine which regions you want to serve. We have different regions with different prices. See pricing below. Then in your websites code you have to refer to the CDN address for those parts you wish to copy to the CDN. Everytime someone visits your website from a distant region the CDN will decide from where it serves the files to that particular visitor.
