A "cloud" is basically a virtual cluster on which you can rent
space/resources as needed. Technically, Amazon's EC2 is more for what's
known as "utility computing," which is what I'm hoping to do. Heavy
computation on the fly:
*"Utility computing* is the packaging of computing
resources<http://en.wikipedia.org/wiki/Computational_resource>,
such as computation and storage, as a metered service similar to a
traditional public utility
<http://en.wikipedia.org/wiki/Public_utility>(such as
electricity <http://en.wikipedia.org/wiki/Electricity>,
water<http://en.wikipedia.org/wiki/Water>,
natural gas <http://en.wikipedia.org/wiki/Natural_gas>, or telephone
network<http://en.wikipedia.org/wiki/Telephone_network>).
This system has the advantage of a low or no initial cost to acquire
hardware; instead, computational
resources<http://en.wikipedia.org/wiki/Computational_resource>are
essentially rented. Customers with very large computations or a sudden
peak in demand can also avoid the delays that would result from physically
acquiring and assembling a large number of computers."
