So, in the generally frustrating wait for a yet-to-be-announced new Mac Pro, I've begun looking around for alternatives (don't really need a Mac Pro, just a large compute engine, but I'm beholden to the Apple shiny...) Anyway, I got thinking - a lot of folk are thinking that Apple's new datacentre will be all about data (especially media) in the cloud. But does anyone think that they might also be offering a compute cloud as well, a la Amazon's EC2? I think it might be a good idea. I don't actually need the power of a dual-hexa all the time, and so I could save money by only renting the power when I needed it. Amazon have shown that compute in the cloud is viable, and Apple have the money to realise a serious competitor. Would you use a Mac Pro in the cloud? What objections would there be (other than bandwidth clogging)...?
