Google et al. do essentially run their servers on EC2. However it's their own version of EC2, in their datacentres. They have a whole pile of virtualised servers they can turn on an off by the minutes. They have internal accounting systems so that each team is 'charged' based on what they use. Google are so big, so it's cheaper for them to make their own datacentre than use someone else's (i.e. Amazon's).

EC2 only came about because Amazon run their servers on it, and they had so much spare capacity, so they sell it.

False.

If by EC2 you mean "bunches of servers", sure.

On GoGrid you can buy cloud servers, or you can rent dedicated servers (and you can intermix the two). The latter are quite a bit less expensive for a given quanta of resources, while the former obviously offer greater dynamic flexibility (with a significant premium).

Actually considering the terrible I/O rate of services like EC2, dedicated often offers a dramatic advantage.

But they don't. So they use none of the upside, and have all of the downside. Yay!

That's not true at all. We shut down machines when we are over capacity (rarely) and we often have to bring up a bunch of new machines where there is a traffic spike.
