The company also offers higher-end Windows and Linux servers, available with Plesk and cPanel respectively. We were very intrigued to see that the company offers low-end Atom-based dedicated servers as well as the more traditional Xeon-based machines. One great resource for those doing some basic experimentation, or site development, is that it has a free, three-month trial for one of its lightly equipped Atom servers.
A Content Distribution Network (CDN) is a network of servers distributed geographically. The purpose of a CDN is to deliver content on the internet much faster. If a user in Toronto is trying to access your website, the closest server to them will take care of this. But someone coming to your website from Sydney, Australia, will be catered to by a server closest to them. The main host server holds your website content, and all the other servers have a cached version each.
