The Customer Perspective
“To remain ahead in this industry, you have to constantly deliver
new solutions that continue to add value…
We needed a platform that not only enabled rapid time-tomarket… but one that would increase our ability to continually
add new products and services.
We chose the Microsoft platform…”

Server Controls
• Programmable, server-side objects
– Properties, methods and events
• Encapsulate both behavior and rendering
– HTML, XML, WML, script, etc.
• You can create server controls
– Custom controls
– User controls
– Or derive from existing controls

Analyst Perspective On .NET
“.NET is a brilliant strategy that enables Microsoft to define the next
shift in the software business.”
Gartner Group
“Everyone should build on the
XML/SOAP foundation.”
Meta Group
“Gartner believes Microsoft is now
providing more vision and influence
regarding this shift than any other vendor.”
Gartner Group
“.NET is a leading example of what we
believe will be the dominant architectural
model for the third generation of Internet
applications.”

Reservations
Dollar cost-effectively opened up another sales channel that has
provided thousands of new reservations per year, equating to
millions of dollars in additional revenue
Partner connection richer, deeper and more dynamic – live with 25
partners in 2 months!
Customer Feedback
“We knew exposing our reservation system as a
Web service would provide a standard interface
that could be used by a wide range of other
applications, both internal and external.
However, at the time, we had no idea just how
often we would use it, or the magnitude of the
benefits it would deliver.”

What is UDDI?
•
Universal Description Discovery and Integration is an industry-wide project to
standardize the discovery of web services.
–
•
Major vendors including Microsoft, IBM, Sun, Oracle and HP
Interoperable, cross-platform specifications
–
–
–
Publish and search
Based on Internet standards
Specs will be transitioned to a standards body.
•
Collaborate on standards, compete on implementations.
•
Public and Enterprise Implementations
–
UDDI Business Registry (UBR)
•
•
–
Public Internet registry operated by Microsoft and IBM, SAP and HP
Fully replicated, entirely interoperable
Enterprise UDDI Services in Windows Server 2003
Scenario: Dynamic Application Configuration
Enterprise UDDI Services allows dynamic configuration
Web services
1.
Each sub registers financials web services
in enterprise UDDI
2.
Financial reporting system at HQ reads
UDDI to discover each sub’s web service
3.
Financial reporting system uses web
service to read financials
4.
Financial reporting system presents
consolidated financial statement
5.
Adding a new sub requires UDDI
registration but no change in report app

Yesterday: Hardwired endpoints built with proprietary
messaging frameworks
– Point to Point
– Difficult, Expensive
– Not business context driven
Today: Loosely coupled endpoints built on standard
messaging framework
– End to End
– Easier, Lower Cost
– Business context driven
