1. A Case Study: WI DOJ Wisconsin Digital Government Summit 2007 November 28 Presentation Shared Service Models and Architectures

2. DOJ Goals
Delivery of relevant information to law enforcement & other authorized entities
Reduce cost of delivery development & ownership through reuse
Utilize national standards
Consolidate/Standardize user identification & offer common behavior to users/applications

3. DOJ Plan
Goals can be achieved by replacing legacy system with a service-based architecture
Attributes: Secure, Reusable, Flexible, Scalable, Highly Available, Supportable, Agnostic

4. DOJ’s Approach
in 5+ steps

5. Step 1 – Small Pilot: AISLE
Learn how to . . .
Build reusable web services
Work with XML
Create schemas
Parse/validate instance documents
Create WSDL’s
Exchange information with other entities
Resulted in XML requests/responses for out-of-state queries & XML rapsheets

6. Step 2 – Pause and Think
Define and design the infrastructure needed for a large project (first iteration of eTIME)
Review available technologies and match them to system needs where applicable
Open source web application server
LDAP for central user repository
Clustered databases
Storage Area Network (SAN)
XML Gateway appliance
Global Justice XML Data Model (GJXDM)
Load Balancing/Automated Failover

7. Step 2 – Pause and Think Operating model is multi-faceted: Web SSO
enterprise directory (Justice Directory)
But this effort is large in scope and will take time.
It was better to deliver something in the short term.

8. Step 3 – Implement Something
Work simultaneously on functionality and infrastructure
Implement infrastructure incrementally
First iteration
Necessary network changes
Implement “Justice Directory”, LDAP service library, and user management facility
Initial applications authenticate against JD

9. One Such App: eTIME

10. Another Such App: WIJIS Justice Gateway

12. Step 4 – The Big Bang
Implement remainder of infrastructure and core services
eTIME browser application and server-to- server capability, based on:
Apache/Tomcat Web App Server
Oracle RAC environment
Intel/Sarvega XML Security Gateway
GJXDM schemas and WSDL
CISCO Content Switches

13. Steps 5 - N Continue to build new services
Add server-to-server partners
Enhance/improve existing services
Improve utility of Justice Directory

14. Enterprise Authentication
Presently: Multiple applications using reusable authentication code & accessing shared Justice Directory
Desired: Multiple applications integrating with shared services for authentication and user profile access
One means to this end is Federated Identity Management
