Excellent intro to ESB - due for new edition
on July 6, 2012
Through twelve chapters, David A. Chappel lay out core elements of the enterprise service bus, the ESB. He discuss advantages of ESB in regards to other solutions such as hub and spoke and portal server. The text is ordered in a logical manner. Albeit the first 3 chapters deal with the rationale and history behind ESB, the following chapters, 4 through 12, delve deeper into detail in regards to business modeling and technical solutions. Technologies visited include - XML, SOAP, JMS, BPEL4WS, EDI VAN and MOM. Theres a heavy usage of 3 letter acronyms throughout so an aspiring integration architect is wise to keep notes while researching the content.
As Chappel provide coding examples in several languages, it is obvious you should have a reasonably good understanding of OO and HTML type languages in order to get anything out of the snippets provided. In addition to the coding, the book is rife with graphical models utilizing a modeling language which was novel to me. Fortunately, all is explained in an appendix section which include description of the stencils. They are probably useful but are a little confusing at first glance.
If there's a main drawback, it is that the book is due for revision and updating. Some info is dated, hence the 4 stars. However, although ESB was released in 2004, it is remarkably relevant considering the years passed. It is important to note that the author was employed at Progress Software when the book was written. Accordingly, the content pertain to Sonic software, which is a more of a "clean" ESB solution than webMethods, for instance, which implements a wider spectrum of solutions.
All in all, I'll recommend Enterprise Service Bus if you are in the business of integration, BPM and related fields.
