I have been using EC2 Beta for a while (including S3). The additional news
(besides being open to everyone now) is the new instance types (small, large
and extra large) and the concept of the EC2 Compute Unit (CU). Small is the
same computational unit as the original beta program ~ one 32-bit virtual core.
Large has two virtual cores and the cores run twice as fast (4 CU). Extra large
has four virtual cores (8 CU). Both large and extra large are 64-bit platforms.
Note, the original advertised speed of 1.7 Ghz was also "downgrade" to 1.0 -
1.2 Ghz for the 1 CU (probably due to user complaints). I have a CPU intensive
application that runs 2-3 times slower than on Amazon's virtual machine vs. a
physical 1.0 Ghz computer. Keep this in mind, if you decide to use EC2.
Beyond that, I think there is a real future in EC2 as a business model. Buying
EC2 units instead of physical PCs is appealing due to the inexpensive price to
performance ratio. I am looking forward to when they support other operating
systems naively besides Linux and add better options for a persistent file
system.
