9:45 AM Saturday Room: Hearthside LoungeThe .NET services bus is part of the new Microsoft Cloud Computing Windows Azure initiative, and arguably, it is the most accessible, ready to use, powerful, and needed piece. The service bus allows clients to connects to services across any machine, network, firewall, NAT, routers, load balancers, virtualization, IP and DNS as if they were part of the same local network, and doing all that without compromising on the programming model or security. The service bus also supports callbacks, event publishing, authentication and authorization and doing all that in a WCF-friendly manner. This session will present the service bus programming model, how to configure and administer service bus solutions, working with the dedicated relay bindings including the available communication modes, relying on authentication in the cloud for local services and the various authentication options, and how to provide for end-to-end security through the relay service. You will also see some advanced WCF programming techniques, original helper classes, productivity-enhancing utilities and tools, as well as discussion of design best practices and pitfalls.
11:00 AM Saturday Room: Hearthside LoungeThe .NET services bus was developed with solving the connectivity issue of web services, and as a general way of relaying messages to services. But controlling a messaging junction in the cloud has the potential for much more than messages relay. The services bus can act as a sophisticated interceptor, adding valuable aspects to your application. The first such aspects are routing and queuing. You can install a router to send messages to multiple subscribers or act as a load balancer. You can have the services bus queue up your client calls until the service is ready to process them. You can combine routers and queues, and have queues and routers subscribe to routers, enabling application features that would be very difficult without the services bus. This session presents the new capabilities and the new design patterns and pitfalls. You will also see some advanced WCF programming techniques, original helper classes, productivity-enhancing utilities and tools.
