A new service by Amazon has surfaced. It combines their computing cloud with their storage surface to bring the power of super computers into your backyard. It is meant for heavy and intensive jobs like web indexing, log analyzing, or even scientific simulation. It is basically an automatic interface that will create your computing cloud instance, allocate the proper resources, do the job, then remove the computing cloud instance. You only pay for the resources you use.
