Amazon S3 - Simple Storage Service
Amazon web services has just launched Amazon S3 - Simple Storage Service.
S3 is a web-based storage system with a web services API. Storage
costs are $0.15 per GB-Month of storage and $0.20 per GB of data
transferred. S3 has an authentication mechanism that is intended
to allow or limit access to your data. There is some good API documentation too. Is the price too high? Hard to say, but if, for instance, I wanted to keep my music collection on S3 so that I could access it where ever I am without having to carry an iPod with me it would cost about $6 per storage (for 40GB) and about $3 for bandwidth (estimated for 100 plays per day that's 100 * 5mb == .5GB) ... for a total of $9 per month. It'd be cheaper to subscribe to Yahoo Music Unlimited for $4.99 per month.
