Learn BizTalk with the free trial and tutorials

During the Microsoft Partner Academy BizTalk class I was working with Lesson 5 (BAM) of the online Microsoft BizTalk tutorials. Out of interest I started to follow the complete course from the beginning.

The tutorials guide you through most BizTalk aspect which a beginning BizTalker should know, in fact it covers almost everything I learned from my paid BizTalk course, but these tutorials are free!

So if you would like to get a hang of BizTalk, grab yourself a 120 day trial copy of BizTalk and download the tutorials.

What is an Enterprise Service Bus?

February 4, 2007   21:24

There is quite a lot of confusion about the Enterprise Service Bus because the leading ESB-providing companies, like Gartner, Sonic and IBM made different definitions of the term.

When we compare all the different ESB solutions we can define a common set of characteristics that apply to an ESB:

• Brokered Communication
  The basic function of a ESB is to send data between processes on a single or multiple computers. The brokered communication is offered by the use of a software intermediary between the sender and the receiver.
• Routing
  Based on a predefined set of criteria ESBs are capable of routing messages to subscribers
• Endpoint Metadata
  ESBs normally maintain metadata that describe the service interfaces and message schemas.
• Basic Web Services
  An ESB supports basic Web service standards like SOAP, WSDL and foundational standards like TCP/IP and XML to communicate.

A lot of venders try to position their ESB as the single solution that solves all integration needs, but an ESB product can rarely do this as it misses features like business activity monitoring and business rules.

Does Microsoft deliver an ESB? No they do not. Of course you can build an ESB with the toolset from Microsoft, but they believe in delivering a broader set of important integration requirements that go beyond the ESB. Microsoft offers message validation and transformation, BAM, Business rules management and business process orchestration & management.
