Eucalyptus: the unsung hero of Open Source?

[ Thanks to GreenITguru for this link. ]

"The only cloud we could use from the commercial sector, at the time we were architecting the system, was Amazon's AWS. Thus we decided to build an AWS work-alike for the Universities participating in VGrADS, do the vgES port to AWS, and then to run the application on the TeraGrid, Amazon AWS, and the various University machines while they were emulating the AWS cloud. Eucalyptus was the infrastructure we built to support the effort at the University sites.

"Because we couldn't change AWS and we didn't have the resources to specialise vgES for more than one cloud API, the quality of the AWS mimicry had to be pretty high. Our goal was to have vgES run in exactly the same manner on AWS and the other Eucalyptus clouds without modification or special purpose code for either."
