AWS Data Exchange for Amazon S3 is now generally available, helping customers easily find, subscribe to, and use third-party data files for faster time to insight, storage cost optimization, simplified data licensing management, and more. This feature is intended for subscribers who want to use third-party data files directly from data providers’ Amazon Simple Storage Service (Amazon S3) buckets, without needing to create or manage data copies, as well as data providers who want to offer in-place access to data hosted in their Amazon S3 buckets.
