The following excerpt from a recent BusinessWeek interview with Jeff Bezos demonstrates how important the "Executable Web" aspect of Web 2.0 (next generation Web comprising two complimentary tracks: Executable Web of Web Services and Syndicated Web or XML based content such as RSS, RDF, OPML, OCS, FOAF etc.).
Q: Amazon.com now runs sites and on-line operations for retailers such as Target and Toys 'R' Us. What's the future for that services business? A: It's a rapidly growing part of our business. And that goes from [large] companies that are customers of that all the way down to individuals using our Web services to tap into the fundamental platform that is Amazon.com. They can build their own applications very effectively. It's almost closer to an ecosystem. Q: So Amazon is becoming a kind of software platform a bit like Microsoft (MSFT )? A: People are building stuff that surprises us. That's what's so interesting about this. We've built this big base of technology to serve ourselves, and now we're opening it up and letting people access it. They're taking these fundamental pieces and building completely new things that not only would we have never gotten around to but in some cases maybe never even have thought of. There are thousands of developers who are building applications using Amazon Web services. The sky's the limit on their creativity. Q: What arises from all those efforts? A: People will be able to build very powerful applications by hooking together a whole bunch of Web services from a whole bunch of different companies. Q: What benefit is Amazon.com getting from this? A: It's too early to say. It's certainly not a major source of revenue for us. But when people use our Web services, they give us credit for that. That turns out to be very helpful.
A few years ago the race was on to simply have a Web Site, then this requirement evolved into a requirement for a database driven site. Today we are seeing the final stages of the Web 2.0 inflection which will inevitably change the focus toward the need for a Point of Presence on the Web for exposing or invoking Web Services and/or Syndicating or Subscribing to XML based content.
