Amazon is now offering unlimited server storage space that is fully redundantly backed up and always available for a very reasonable rate:

• Pay only for what you use. There is no minimum fee, and no start-up cost.
• $0.15 per GB-Month of storage used.
• $0.20 per GB of data transferred.

I can think of lots of uses for this. (Have you priced getting redundant backed up dedicated servers with tons of disk space lately?) This is a good example of a large player taking advantage of their giant infrastructure to offer real benefits to small developers.

Amazon S3 – Simple Storage Service

Amazon S3 is storage for the Internet. It is designed to make web-scale computing easier for developers.

Amazon S3 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. It gives any developer access to the same highly scalable, reliable, fast, inexpensive data storage infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to developers.
