I hope you are on it 

14. How we dealt with Data & Persistense
Application Data
Stored in MySQL DB, indexed and optimized
Yes, we could have used data services, but our requirement is simple
Event publishing and statistical data
The volume is high
Raw data
Persisted in a Cassandra ring
Summarized to useful information and stored in MySQL DB.

15. End to End JSON via REST How we dealt with messaging
To eliminate the mismatches between the presentation layer and the application layer

16. How we dealt with App development
Jaggery all the way – The new server side js framework we created
Development of M & C layers

17. How we dealt with Integration
Managing the API
The API gateway
Accumulating the statistics
Gateway publishes events to BAM
Load Balancing the API calls
Elastically load balance between application server nodes

18. How we dealt with Presentation
Completely written with HTML/5 and Javascript
Styled with CSS/3
Packaged with PhoneGap, for device specific binaries

19. What tools & frameworks we used
InteliJ Idea Jaggery Plugin
WSO2 Dev Studio Jaggery debugger
API publisher
Puppet based deployment
JQuery Mobile for frontend development
