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.

Amazon S3 Functionality
Amazon S3 is intentionally built with a minimal feature set.
- Write, read, and delete objects containing from 1 byte to 5 gigabytes of data each. The number of objects you can store is unlimited.
- Each object is stored and retrieved via a unique, developer-assigned key.
- Authentication mechanisms are provided to ensure that data is kept secure from unauthorized access. Objects can be made private or public, and rights can be granted to specific users.
- Uses standards-based REST and SOAP interfaces designed to work with any Internet-development toolkit.
- Built to be flexible so that protocol or functional layers can easily be added. Default download protocol is HTTP. A BitTorrent protocol interface is provided to lower costs for high-scale distribution. Additional interfaces will be added in the future.

Pricing
- 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.

[NetworkWorld] European Comission to launch public inquiry into RFID. Sembla que a Europa es regularà la utilització de RFID amb legislació. A veure quin n'és el resultat...
The Commission is concerned about the personal privacy and security issues raised by such applications, and intends to hold a series of workshops in Brussels through June to canvas public opinion on the subject. The results of the workshops will be incorporated into a consultation document due to be published in September.

RFID is also a European issue for other reasons. Laws allowing for the free movement of goods around the EU would be worthless if tags on packaged foods from Poland, say, were unreadable by scanners in Portugal, as supermarkets would not be able to track their inventory. The Commission is also considering legislation on technology standards and radio spectrum allocation to ensure the harmonization of tag technology across the EU.
