Come check out my talk at JavaOne this week on Wed at 11:05. Its entitled - "XTP: Patterns for Scaling SOA, WOA, and REST Predictably with a Java(TM) Technology-Based Data Grid (TS-5154)"

Here is an excerpt from the session abstract -

This session highlights specific patterns that take advantage of distributed Java™ platform agent-based caching in an in-memory data and execution grid to enable shared state management with near-in-memory access speeds for state data by services in SOA, WOA, and RESTful architectures. Using these patterns, SOA-based applications can achieve predictable scalability and high availability while insulating organizations from the need to enforce special architectural practices across the organization for "stateless" service development, enabling Java technology-based or .NET services to be written like everyday! objects that encapsulate state data with the business logic that operates on it.

The presentation discusses pros and cons of stateless versus stateful services and the service state repository. It explores architectural patterns for service state management such as fault-tolerent collection,load-balanced fault-tolerant services, business logic affinity, level 2 caching, state-based notification, and claim check. In addition, it examines pros and cons of multilevel service state caching in virtualized environments.

Come learn how next-generation SOA-based application architectures can be built to take advantage of scalable, predictable, virtualized environments that are capable of adapting to the ever-changing needs of the business.

Hope to see you there! Its in Esplanade 304-306, Moscone
