This is a nice introduction to the technology, but I think it's a bit heavy on the technology and not informative enough about the historical context and the problem space. Take this section:


"Today, we face complex issues like distributed software, application integration, varying platforms, varying protocols, various devices, the Internet, etc. Today's software has to be equipped to answer the call for all of the above."


It's my understanding from reading the article that these two lines provide the justification for SOA. In order to do that, more depth is required. Why do we need distributed software? How does SOA provide a better application integration solution than other EAI approaches?


Then there is the historical aspect of the discussion. There is some high level software engineering history but there is no discussion about EDI or other interchange standards.


A whole article could be dedicated just to providing a historical context and issues based justification for SOA. It's that article that would be valuable.


In other words, write an article that shows me that web services with XML is a good idea that fits the problem and is superior to all existing standards. That web services over XML is not another EJB-style Sun hype fest.

    My objective for writing the article was the following:

    1) Give a brief introduction to SOA assuming that the audience is medium-level developer to application architects/project managers.

    2) Provide an overview of the evolution of SOA.

    3) Define and provide some explanation of the key components of SOA.

    Having said that, with the limitations on the length of the article and the assumption of who would be reading the article, I was not able to provide justification for things such as why we need distributed software, EDI, etc. To do that, I would have had to write several books before I could sufficiently cover all that led to SOA.

      I don't think it would take a book to contrast EDI versus web services over XML. Could you give us a couple of paragraphs on it?

        How about a few links that provide some details about xml and EDI:

        1) http://www.xmledi-group.org/
        2) http://www.asptip.com/edi_vs.htm
