Pragmatic Web Services Adoption, October 11,2001
Web Services Analogy:
•Monolithic/Proprietary Design
•Expectation of long technology life
•100% vulnerable to technology changes
•Fixed architecture and capabilities
•Single Source Vendor
Where is this going?
•Component Based Design
•Expectation of rapid obsolescence
•Adaptable to new technology
•Standard Interfaces (IEEE)
•Allows best of breed architecture

implementations

Phase 1 –Inside the Firewall
Pragmatic Web Services Adoption, October 11,2001
Phase 1 Case Study
Investment Bank
￿Had built transactional application on WebLogic. This
application collected research reports.
￿Bank had a need to expose that system to some Microsoft
applications –their employee portal --running on IIS.
￿Used Web Services to expose the transactional system as
a service

Phase 2 Case Study
Chemical Manufacturer
￿Had made large investment in EAI software (e.g. TIBCO,
Vitria, WebMethods, etc.)
￿Tier 2 trading partners could not afford cost of ownership of
EAI solution –many manual processes as a result
￿They plan to use web services to expose their product
catalog to partners. Views will be customized for each
supplier. This view will be a publish only scenario, with
transactions coming further out.

Challenges to Web Services
￿Running applications in a distributed environment is a
serious challenge –particularly as composite applications
from multiple parties are deployed
￿How does a company decide to service enable elements of
their business? What is the impact on the business?
￿How do you get the IT and Business teams to agree on
processes, goals, etc.?
