or away from home

Research and compare vehicles

• Select from makes/models, saved favorites, saved searches

• Study, compare, price vehicles

Contact dealers • Validate membership

number and zip code • Receive dealer

information • Transmit leads to dealers

Varies by territory

Technical  Requirements  

-  Communication between iPhone application and WSO2 ESB should use JSON messages

-  Backend services uses different message formats -  SOAP, REST, POX, JSON

-  Expose services provided by multiple vendors as composite services -  Minimize iPhone to ESB service calls by aggregating backend services -  Expose AAA internal database as services -  Monitor activity of Mobile Service Gateway

Deployment  Architecture  

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

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

MS SQL JDBC

Monitoring

•  WSO2 BAM is used to monitor services exposed by WSO2 ESB •  Push model

•  Presents statistics in dashboard and as reports •  Email alerts •  Logging

Mediation Statistics Push

Manage Configuration

-  WSO2 Governance Registry is used to store artifacts of -  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

Parallel Processing

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!

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

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

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

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!

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
