Amazon has introduced another new web service -- Amazon S3 (“Simple Storage Service”), which provides a web services interface to Internet-based storage and backup. This is very cool; it's easy to imagine a lot of great uses for this. Amazon provides the web service -- it's up to the rest of us to build the applications. I think a we'll see a lot of interesting applications for a variety of purposes (not just traditional backup). As usual, Amazon provides both SOAP and REST interfaces.
