Amazon S3 - Simple Storage Service
Amazon has announced the release and immediate availability of their Simple Storage Service (S3) built using WS-* protocols. Amazon is positioning S3 as “storage for the Internet”. It provides a simple Web services interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the web. Charging is based on the amount of storage space used, and the download bandwidth used. S3 provides both SOAP and REST-based interfaces.
