– Axis2 AAR– POJO– JAX-WS– JAX-RS

• Mashups– Javascript based services

• Workflows– BPEL

• JSP / Servlets• Server-side Javascript - Jaggery• Stratos 2.0 Cartridges Architecture - Language

independent application development - PHP, Ruby, Python etc.

Application Development

• Connecting disparate business applications into an integrated solution

Enterprise Integration

Governance

Security and Identity Management

I hope you are on it

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.

How we dealt with messaging

• End to End JSON via REST– To eliminate the mismatches between the

presentation layer and the application layer

How we dealt with App development• Jaggery all the way – The new server side js framework we created

– Development of M & C layers

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

How we dealt with Presentation

• Completely written with HTML/5 and Javascript• Styled with CSS/3• Packaged with PhoneGap, for device specific binaries

What tools & frameworks we used

• InteliJ Idea Jaggery Plugin• WSO2 Dev Studio Jaggery debugger• API publisher• Puppet based deployment • JQuery Mobile for frontend development

The solutions architecture

How can we make it more “enterprisy”

Where it all Runs

Questions folks ?

Thank You !
