In more modern cloud systems like Amazon EC2 or the Rackspace cloud, you're sold a service based on objective standards for how powerful your resources are. Amazon has their "ECU
". You know in the beginning that you share physical hardware with lots of other people, but you're guaranteed your minimum square footage and they can't subdivide your unit into smaller pieces. You know that your service won't degrade over time. Not so with traditional shared-server hosts like Dreamhost. A Dreamhost account gets less and less powerful with each passing year because they pack customers into their servers like sardines.
