Service Bus is the messaging and connectivity fabric of Microsoft’s Windows Azure AppFabric cloud-middleware platform. Service Bus provides endpoint-federation for Web services across network boundaries and topologies with NAT and Firewall traversal today and will, in the near future, also provide rich decoupled messaging services with publish/subscribe capabilities. In this presentation, Clemens Vasters, an Architect on the AppFabric product team at Microsoft will provide an overview of  Service Bus as it is currently available for commercial use and will provide a detailed outlook on the new Service Bus features that will become available over the course of this year.
