I have been getting into cloud computing in a really big way/ I just read a great post from Oakleaf System that put a test harness on all the different cloud computing systems out there, With the exception of       s(s)ds (soon to come) and Google. It is a great through down and worth a read.  Here is a link to the article

Here is a spoiler if you don’t have time to read the whole thing

Following is a comparison of EC2 execution times with those of the original OakLeaf Systems Azure Table Services Sample Project that’s described at Azure Storage Services Test Harness: Table Services 1 – Introduction and Overview, et seq.

Action:	Page	Count	Insert	Delete	Create	Update
EC2 with SQL Express	0.005	0.002	0.019	0.380	0.112	0.374
EC2 with SimpleDB	0.048	0.094	0.048	10.094	22.142	10.855
Azure Table Services	0.215	0.188	0.155	5.820	5.310	6.561

I was surprised to find Azure Table Services’ execution to be substantially slower than EC2 with SimpleDB for single-page SELECTS, iterative counts, and single INSERT operations.

With the exception of the Insert operation, you can verify the Azure Table Services timing data because the harness is available whenever Azure Data Services is up. EC2 services will be made available on request for brief periods (contact roger_jennings[at]compuserve[dot]com).

Make sure you read the comments there worth a gander.
