The Windows Azure AppFabric Service Bus: Topics

摘要

It's no secret among my colleagues that the Windows Azure Service Bus functionality didn't really get much support from me. However, with the Windows Azure AppFabric CTP June Update, Microsoft has finally added enough features to move the Service Bus from what I considered not much more than a placeholder to a truly useful technology. For my purpose here, the essential piece of messaging technology the AppFabric Service Bus now offers is Topics, a rich publish-and-subscribe capability. I'll focus on Topics in this article and draw, as I am so often apt to do, from my retail industry experience to look at how the technology can be used to facilitate inter-store inventory checks.
