The project encourages developers, researchers, universities and businesses to upload large (non-confidential) data sets to Amazon — things like census data, genomes, etc. — and then let others integrated that data into their own AWS applications. AWS is hosting the public data sets at no charge for the community, and like all of AWS services, users pay only for the compute and storage they consume with their own applications. Data sets already available include various U.S. Census databases, 3-D chemical structures provided by Indiana University, and an annotated form of the Human Genome from Ensembl."
