Kent Weare provides an introduction to Microsoft Azure Service Bus. Service Bus enables integration, routing, coordination, and messaging capabilities in the cloud. It includes Service Bus Relay for interconnectivity across network boundaries, queues for decoupled messaging with load balancing and disconnected clients, and topics for publish-subscribe capabilities. The presentation demonstrates usage of Service Bus queues and topics with a scenario of a power generation company updating a dashboard on generator commitments and dispatching via mobile devices.
