WSO2 support engagement model-  QuickStart-  Development Support-  Development Services-  Production Support-  Turnkey Solutions

AAA Mid-Atlantic-  Part of the AAA association, serving more than 50 million members across the United States-  One of over 40 AAA clubs-  Territory extends from Virginia through New Jersey-  Customers include more than 3.5 million members

AAA Mid-Atlantic Products Roadside Discounts Insurance assistance Maps and Travel Auto repair directions booking Auto Driver Retail Buying training

Business Requirements-  Deliver an iPhone auto buying app for the entire AAA Association-  Deliver an app that works for different clubs with -  Different fulfillment options -  Different business rules-  Provide the following functions: -  Allow all users to research and compare vehicles -  Present member prices to members -  Allow members (in some territories) to buy cars at guaranteed member prices

Simplified Application Flow Varies by •  Validate membership number and zip code territory Contact dealers •  Receive dealer information •  Transmit leads to dealers •  Select from makes/models, Research and saved favorites, saved searches compare vehicles •  Study, compare, price vehicles •  Specify shopping location Enter •  Intent is to allow shopping near Shopping Zip or away from home

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 DataData is stored in MS SQL databaseStored procedures exposed as SOAP web services using WSO2 DSS35+ backend service operations created just using XML configuration JDBC MS SQL WebService

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 Mount Mount Mount

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 APIs-  Ability to create reliable composite services-  Ability to consume services with various message formats-  Ability to create data service APIs-  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
