Building A Country On Java OpenSource
8:30 AM MDT
Transitioning the citizen services completely open source - utilizing Java. Migrating and restructuring existing services and departments into a single cohesive scalable resource for delivering online information for services such as, vehicle information, civil service, judicial and anything else a government entity will require. A complete SOA restructuring of disparate systems, languages and services built on proprietary systems, integration of non standards compliant web services, databases, regionally distributed system while increasing uptime, scalability, response time and management of a single master data source.
A case study of the transition from disparate government entities, various forms of delivering data, lack of a uniform schema and several political boundaries. During this session we will look at setting up a message driven asynchronous infrastructure to rapidly integrate legacy systems requiring web services, JPA, JDBC into a common dictionary, structure and cluster ready system. All based on existing and open Java API's, technologies and easy to use frameworks. We will show how to effectively combine SOA techniques with modern Key Value stores, effectively use OSGi and JPA, rely on proven api's as JMS and combining all of these with existing and well proven Apache Java offerings. We will address scalability, security, systems design and rapid development of highly robust web services and stateless interfaces for high load systems. In the end of the session you'll have a complete overview of a big data system based on Camel, Karaf, CXF and Cassandra. A completely message driven design that interacts with legacy systems encompassing many commercial and open source offerings commonly used.
