5. August 2001Copyright UserLand Software 2001 Web Services

6. August 2001Copyright UserLand Software 2001 What are Web Services? A new architecture for the Web Moves the Web from documents to data Separates form from content

7. August 2001Copyright UserLand Software 2001 The technology of Web Services Transport: SOAP (supported by the big companies) and XML-RPC (an easy to use subset of SOAP) Data format: XML Discovery: UDDI or modified DNS

8. August 2001Copyright UserLand Software 2001 What do Web Services Do? Allow applications to talk to each other Allow people to build new applications that draw on the resources of hundreds of other applications Allow storage of information in the cloud for use by many applications (Hailstorm)

9. August 2001Copyright UserLand Software 2001 Peer to Peer (P2P)

10. August 2001Copyright UserLand Software 2001 What is P2P? A new computing architecture Moves the Web from a client-server model to a client-client model Makes desktops the equal of servers

11. August 2001Copyright UserLand Software 2001 The technology of P2P Presence: where are you located (dynamic IP addresses, Firewalls and NATs)? Tunneling: how can I reach you (Firewalls and NATs)?

12. August 2001Copyright UserLand Software 2001 What does P2P do? Allows people to share files with each other (Napster) Enables real-time messaging (ICQ, AIM, Microsoft Messenger) Massively parallel supercomputing (SETI at home)

13. August 2001Copyright UserLand Software 2001 Desktop Web Applications

14. August 2001Copyright UserLand Software 2001 What are desktop Web applications? Applications that use the browser as the interface Web pages are served from the desktop to the browser Consume and publish Web services

15. August 2001Copyright UserLand Software 2001 The technology of desktop Web applications A desktop scripting environment (Microsoft.Net and Radio) A desktop content management system, database, and HTTP server (Radio) Connections to SOAP, XML-RPC, and P2P networks (.Net, Radio, and Jabber)

17. August 2001Copyright UserLand Software 2001 Implications for Broadband

18. August 2001Copyright UserLand Software 2001 Less = More Less data needs to be transmitted More frequent scheduled updates are made (lessons from PointCast) Rapid organic growth due to P2P (old saw: other people’s bandwidth (OPB) is free

19. August 2001Copyright UserLand Software 2001 Typical Explosive Application Entertainment network tied to TV show Local participants create video files and submit them to the show’s desktop Web application Files are shared among participants via P2P and voted on via SOAP and a desktop Web app Cost to the TV producer: Low Cost to the network providers: Huge

20. August 2001Copyright UserLand Software 2001 Implications Bandwidth use will even out (fewer spikes) due to data transmission scheduling Bandwidth use will occur round the clock Overall usage will rapidly rise as users add new desktop Web applications

21. August 2001Copyright UserLand Software 2001 What to do? Experiment: build your own Web apps now Charge users for average bandwidth utilization rather than flat fees Build fast last mile connections to reap the benefits
