i wonder how the back-end systems are configured. one would guess the instance you pay for is not a VM since you cannot access the GPU directly, unless Amazon figured out a way.

I believe it's kVM from what I've read. You get 2 Tesla cores, which unfortunately, only crack at about 49k PMK/s. It's too bad they didn't use Radeon 6990s. :P Those would get 280k PM/s and cost less.
In my country its so dificult to find the TESLA core and its so expensive....!!
I do pretty well with my Nvidia GTX 480 (Fermi) at 180K KP/S. Unfortunatley not 64bit until BT5 so kinda limited in terms of tables.
I could probably take the time to set it up as 64bit manually but im just too lazy.

http://stacksmashing.net/2010/11/15/...gpu-instances/"As of Nov. 15, 2010, Amazon EC2 is providing what they call 'Cluster GPU Instances': An instance in the Amazon cloud that provides you with the power of two NVIDIA Tesla 'Fermi' M2050 GPUs... Using the CUDA-Multiforce, I was able to crack all hashes from this file with a password length from 1-6 in only 49 Minutes (1 hour costs $2.10 by the way.). This is just another demonstration of the weakness of SHA1 — you really don't want to use it anymore."

I'm a compulsive post editor, you might wanna wait until my post has been online for 5-10 mins before quoting it as it will likely change.
I know I seem harsh in some of my replies. SORRY! But if you're doing something illegal or posting something that seems to be obvious BS I'm going to call you on it.
Well yes and no, he provides some clarification over here (or tries to anyway):

Yes, if you want speed over reliability. I personally would not want my cracker to miss cracking the password/hash, which in my eyes is a failure.
I have a hard time believing the accuracy of those numbers. Benchmarks are almost always higher than the actual.
Here's a few posts to sink your teeth into:
