All the "web-scale" applications that don't want to buy their own machines.

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.
> (And as we all know, buying

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.

The average person can't afford to buy a hundred big computers. But
then, the average person can't afford to rent a hundred big computers in
a cloud either. So it seems like a moot comparison to me.

If things like maintenance, backups and disaster planning are important
to you, then yes, cloud computing probably makes a lot of sense. But if
you're just some dude trying to render stuff with POV-Ray, it makes far
less sense.

Only makes sense if you're using the system to provide a service to
somebody else. If you're just running a computation for your own benefit
then there aren't going to be "rushes" or "overflows".

Nonsense. Amazon's computers are like $0.09/hour.
http://aws.amazon.com/ec2/#pricing
100 "small" amazon computers are $9/hour.

It depends how fast you need things.

You asked for a good reason; I gave you several. Some of us actually make
money with computers.

...which works out to $216/day or $1,512/month - which is slightly
outside most people's budget.
By contrast, buy a big computer, put it in your loft, leave it running
all year. It'll cost maybe £500 to buy in the first place, but at the
end of a year you'll have a finished result.

Some *companies* make money with computers; it's news to me that
individual people can do this.

What, $2/day for a 24-hour pov-ray renderer? If you only need 100 compute
rs
for a day, $216 is really not a whole lot of money.

Well, sure. You can buy one computer and take a month to do something, or
rent 100 and take a couple hours to do something. Note that if your progr
am
takes a year, that's 100 computers for about 1.2 days, so you come out
ahead. Admittedly, you don't have the computer at the end of the year, bu
t
you saved a year's worth of time and electricity too.

Uh, OK. I'm sorry to hear that.
