Average Reviews:
(More customer reviews)A surprising amount of the spending for information technology in virtually all organizations is spent on supporting, updating, integrating, or otherwise maintaining legacy systems. SOA is an attempt to define a generalized group of services oriented 'objects' (for lack of a better term) that have a well defined interface and output that is oriented to provide a business orjective.
Most books on SOA (do a search at Amazon) tend to be oriented around the web and the transfer of information between computers using various web protocols, especially SOAP and RSS. In essence these are putting the details before the concepts.
This is a book on the concepts, it is what we are trying to do with SOA more than the details of how to do it. It is more concerned with good business practices rather the details of implementation. It is particularly good at refraining from recommending any particular vendor or technology.
A question you have to ask yourself is, 'Is now the time?' The authors say yes, that despite the history of attempts like CORBA, COM/DCOM, etc. there is now enough industry momentum behind current techniques that it is clearly time for you to get started. This is one of those places where it is easy to predict the future, it is harder to get it right.
Still, I think the broad concepts brought out here will last, even if the details of the implementation do not. And these concepts is what this book is about.
