After a general overview of the application, this talk will discuss the following features, focusing on the high level architecture and used technologies:

  • Service auto-discovery & failover with Cluster4spring and JMX
  • Service state replication with Terracotta
  • Dynamic service management through a JMX proxy layer
  • Scenario management rule engine.
  • Scalable high resolution rendering with Batik SVG toolkit (>10000px by >5000px)

If you are interested in the do and don'ts in the design of mission critical 24/7 application, and its common pitfalls, this is a talk you can't miss.
