A Cloud Server is a virtual dedicated server instance based on our custom implementation of the Xen Hypervisor that runs on very robust hardware. These server instances offer truly dedicated and protected resources unlike a traditional VPS (virtual private server). While you may get a small portion of dedicated memory, there is generally no dedicated CPU allocation, disk i/o, network i/o, etc. In addition, most VPS providers only offer smaller amounts of resources, 256MB to 1GB of memory and no options above this. The largest problem by far is that VPS platforms are typically oversold making one physical host machine run far too many customers. This turns into a resource allocation nightmare causing server crashes or poor performance (or both). There is no isolation from other customers.

With a Cloud Server you always get the full amount of allocated memory, CPU, network i/o, etc that you are paying for and there are some great perks as well, such as the ability for your CPU allocation to burst when there are free CPU cycles on the host machine or when it is heavily underutilized. So often you end up with far more CPU allocation than what you are paying for as the host servers powering Cloud Servers are never oversold.
