In this chapter, we have introduced the basics of BizTalk Services and the concepts, architecture, personas, and tools available to build an integration solution. We also exercised all the concepts learned through a simple order processing scenario with BizTalk Services and Service Bus relay and queues. The example can be further extended to include transforms, routing to other bridges like EDI, custom code, and so on. In the next chapter, we'll look at some of the BizTalk Services capabilities in more detail.
