Windows Azure Service Bus
is a hosted, secure, and widely available infrastructure for widespread
communication, large-scale event distribution, naming, and service
publishing. What would
the best place be to learn more about this technology? The
Windows Azure Service Bus Resources, which is an excellent entry point to get access to some of the many community resources for the Windows Azure Service Bus. Studying the service bus can be another challenge next to BizTalk yet with the new cloud capabilities
with BizTalk Server 2013, you will need to (see
BizTalk Server 2013: Connect to Azure Service Bus).
It is possible that after gaining experience- and building/strengthen your knowledge in BizTalk you want to take it a step further by learning the ESB Toolkit. If you have your BizTalk environment available you can download and then install and configure
ESB Toolkit 2.2 (Version 2.2 is target for new BizTalk 2013). For reading you can start with a
white paper by Jon Flanders.
