A true cloud host can scale up and down on demand, adjust storage sizes, etc. Amazon's AWS is a true cloud provider. I manage a large snack/gift type site. They used to cripple multiple dedicated servers every holiday season but then have to choose between paying for the infrastructure in the off season or scaling up for a few months out of the year. On AWS we can automatically add servers and then serve catalog images via a CDN when the need arises. Right now hosting costs are a fraction of what they are in the holiday months. If traffic spikes, the new instances will be launched to meet the demand.

I know AWS well but by the looks of it rackspace is pretty legit too.
