Amazon, Clouds, etc

I've started thinking more about virtual computing recently.  Had a
poke around Amazon's site to get a better view a few weeks ago
(thought I had posted something here, but can't find it - they have
quite a lot of documentation and it's nice + clear).

Here's a more managementy view of the whole thing, motivated by
Amazon's recent announcement of various security features.

And here's where you start for info on Amazon's EC2 etc -
http://aws.amazon.com/ec2/

The latest edition of CISE contained some articles on cloud computing,
including a couple of quite good ones on how to use them to solve
variosurs problems (SQL-like queries and graph algorithms) -

(most are likely subscription only; it's the only magazine I subscribe
to - looks a bit amateur, but actually covers exactly what I do for a
living)

BitBucket Outage Details - Cloud v DDOS

From: andrew cooke <andrew@...>

Date: Sun, 4 Oct 2009 18:18:37 -0400

I am a little surprised that Amazon didn't handle this better - a DDOS
attack wiped one of their users off the map.  On the other hand, other
users were unaffected.

The post linked from there is a little self-promotional, perhaps, but
worth reading anyway -
