If you work with non-profit projects that collect or disseminate large amounts of public data, you would find this interesting.
Amazon offers FREE storage for huge public datasets. So in otherwords, Amazon's 'cloud based' storage service (known as S3) will offer, for no charge, to store a dataset if it is open to the public and somehow for the public good.
From their site:
"Public Data Sets on AWS provides a centralized repository of public data sets that can be seamlessly integrated into AWS cloud-based applications. AWS is hosting the public data sets at no charge for the community, and like all AWS services, users pay only for the compute and storage they use for their own applications. Learn more about Public Data Sets on AWS and visit the Public Data Sets forum." (from Amazon's Public Data Sets)
