AGENDA
The Services Oriented Host
• Brief on SOA
• SOA beyond the ‘Service’
• Requirements for existing systems
• Service Oriented Host
• Use Case Scenarios
WHY ARE WE TALKING ABOUT SOA?
“
A services-oriented architecture
(SOA) approach to IT can bring
agility and long-term savings to
businesses.
”
—PC Magazine, September 2004
SOA Is Part Of The Computing Cycle
What Is A Service-Oriented Architecture?
If a service is like a
musical instrument...
...Then SOA is like an
orchestra
Service Oriented Architecture
Let Services be
Services
and that’s all…

Purpose? General, vertical, horizontal
How?

The Service Oriented Host
» This is about taking advantage of the promise of SOA
• It is not completely about the use of Web Services
• Web services is an implementation
• It is about correct use of existing applications within a
services approach
» Use a Services approach; transactionalize, add extensions,
create services, allow tactical use of Host Applications
within the push to SOA
Use Case Scenario
Kansas JobLink
A Services Oriented Host
The Issue
Discerned a problem on the horizon
» Economic climate change
• Cyclical demand requirements
• Currently approaching peak service requirement
• Unemployment rising
• Projected growth of claims processing in the double digits for
the next several years
» Inability to service the demand with current systems
• Anticipated increase in claims to 250,000 per year
• Call centers running at capacity of 110,000 claims per year
Current System
IVR
Terminal Emulation
CICS application
Call Center
Client Applications
Mainframe
Current Infrastructure
» IS Staff
• Internal IS staff developed legacy systems
• Consultants developed VB app with Internal IS
staff maintaining systems
» Call Center Staff
• Strong background using original "paper"
system and CICS transactions
• Trained in MS Office
• Trained to use GUI-based system
Business Objectives
» Modify customer service delivery model (add channels)
• Expand from phone to Web based self service
• Redesign IVR script to provide self service
» Extend hours of operation
» Reduce the time an agent needs to spend with customer
» Provide an agile platform to accelerate development times
• Improve existing software performance throughput
• Reuse code
• Reduce delivery risk
Looked At Two Options
» A grant team reviewed the requirements
» Two solutions were proposed to address the
requirements out of the review
• Mainframe service technology
• Reengineer the legacy system to a client server
environment
Mainframe Service Technology
Reengineer the legacy system
to a client server environment
Requirements Re-evaluated
» Combined critical path requirements
• Business requirements
• Staff skill-set capabilities
» Re-use capabilities
• Retention of existing systems
Solution evolved out of ability of new open and
market standards to access the critical legacy
systems
A Services Approach
» Issue was how to work in KDHR preferred
environments without throwing out Legacy
Systems
» Apply a Services Oriented
Architecture to the legacy systems

Benefits Applied
» ROI in less than a year
» The standard benefits used to bolster a services
oriented architecture were realized
• Simplified integration
• Agility
» Open standards made it a safe decision
• Use of accepted standards facilitates use with
future systems and technologies
• These solutions will be accounted for…
