Microsoft last week announced the release of version 1.0 of the Service Bus for Windows Server. The Service Bus for Windows Server provides Windows Azure Service Bus messaging capabilities on Windows Server allowing customers to build, test and run message-driven applications in self-managed environments and on developer computers.
By releasing this component which works the same as the component in Azure, Microsoft makes it easier for companies leveraging the technology to later decide to host the application using the Service Bus to Windows Azure. The Service Bus is able to replace other so called Message Queuing (MQ) applications.
