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

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)

Peer to Peer (P2P)
August 2001
Copyright 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
August 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)?
August 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)

Desktop Web Applications
August 2001
Copyright 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
August 2001
Copyright 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)

What do you do with desktop
Web applications?
• New applications that integrate data from
multiple applications and distributed
desktops
• Distributed e-commerce
• Personal publishing and knowledge
management

Implications for Broadband
August 2001
Copyright 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

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
network providers: Huge

Cost to the
Copyright 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
August 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
