The 1000 Genomes Project is an international genomic research and data collection effort that has produced "a deep catalog of human genetic variation" for public research use. Now, thanks to Amazon Web Services (AWS) and the White House's recently-announced Big Data Research and Development Initiative, the 1000 Genomes data is available gratis on the AWS cloud. In reality, there are over 1700 genome profiles in the demographically-diverse study, and all that data takes up about 200 terabytes of memory, according to a New York Times article on the cloud bonanza. So even though researchers could download the data free to their own computers from 1000 Genomes directly before, it's something you really don't want to do, even if you have that kind of memory (re: 200TB). Instead, you'll likely be better off accessing the data through AMS and paying them to crunch numbers for you, which probably explains why AWS has decided to engage in this bit of philanthropy. Future profit, plus their preeminence as a computational resource in the brave new world of Big Data.
