Architecture
• 7 x 4GB dual core VMs
• Clustered MS SQL server

13. Exposing Data
Data is stored in MS SQL database
Stored procedures exposed as SOAP web services using WSO2 DSS
35+ backend service operations created just using XML configuration

- Shared registry instance across multiple products using registry mounts
- Each product has separate registry space
- Shared space to store common artifacts ( WSDLs, Schemas )
- DEV > IST > UAT > PROD migration using check-in/check-out

19. Project Challenges: Geographical Variations
- Primary functionality varies by geography:
- Some territories partner with the Association’s primary provider of vehicle
information and guaranteed prices
- Others use different partners
- Others do not actually offer auto buying
- Secondary functionality varies by geography:
- Cross-promotion of related products (financing, protection, insurance)
- When member prices are shown varies
- The app design had to handle all cases with no sense of degradation!

20. Project Challenges: Overall
- Account for geographic variability
- Connect to multiple partners
- Provider of vehicle data and pricing
- Provider for VIN resolution
- AAA National
- Allow club-specific cross-promotion and messaging
- Abstract changes from the application
- Manage multiple partners
- Maintain close ties with major clubs and AAA National
- Coordinate launch across all of AAA

21. Project Challenges: Technical
- Ability to create JSON API's
- Ability to create reliable composite services
- Ability to consume services with various message formats
- Ability to create data service API's
- Ability to have service monitoring capabilities
- Security challenges exposing internal challenges to internet
- Service response times

22. Results
- Success!
- Store reviews have been positive
- We have passed 10,000 downloads
- Application is allowing members to research and purchase cars
- Architecture has been extremely robust
- Numerous changes have been made without app redeployment

23. Possible Future Enhancements
- Extend application functionality
- VIN recognition
- Overall ownership cost estimates
- Used cars?
- Port to other platforms
- Android
- iPad
- Windows Phone
- The architecture will help us regardless of where we go!

24. Summary
- Reuse of existing services
- Usage gateway pattern and bus architecture to build the solution
- Unified API to hide the complex backend services
- Lightweight API with JSON
- Go to market within a shorter project cycle
- Enterprise solution with scalability, high-availability and performance
