... why you would want to spot-price bid on compute time an hour at a time 
and get canceled if it went above a particular price?

I'm just wondering what all these people are apparently using cloud 
computing *for*... I can't think of a good reason.

All the "web-scale" applications that don't want to buy their own machines. 
Reddit, facebook, twitter, etc.

You would have thought Facebook could afford to buy the entire Internet 
multiple times over...

Still not sure what use this is to the average Joe on the street.

I wouldn't think so.

OK, so you want to render a thirty-minute POV video, where each second takes 
two CPU-minutes to calculate. Begin now.

How is this any different to me just going out and buying a big 
computer? As far as I can tell, the only difference is that you're 
renting compute power rather than buying it. (And as we all know, buying 
is usually cheaper than renting except for one-offs.)

Should I resurrect my BOINC-POVRay project and get everyone in povray.off-
topic to join and contribute CPU? It wouldn't cost me money that way :)

Or going out and buying a couple hundred big computers?  To do a week-long 
render? Then what?

For many "cloud" providers, yes, that's exactly the difference. Plus, you're 
renting by the hour, rather than by the month or year.  Why would you by 20 
high-end computers and rack them up in your house if you can rent it from 
someone else?

For Google, you're using proprietary APIs on their cloud, so if you want to 
take the bulk of it into your own machines, you can't. Until now, which is 
what that announcement was about.

It depends on how much you get with your rental. Maintenance? Backups? Rack 
space? Electricity?  Disaster planning? You still have to pay to run the 
things, and you still have to have stand-by capacity for overloads.

Of course, with something like Amazon, you can rent until your capacity 
warrants buying processors. And then you can use Amazon to handle the 
overflow, or the seasonal rush, or the new product announcement, or whatever.
