<<Myth Number One: Service-Oriented Architectures are a new concept. Not really. We've been attempting to create solutions and technology around the notion of sharing functional behavior, or services, since we have had more than one computer running in an organization. Indeed, RPCs were the first real attempt at providing this type of architecture, then IPCs, and on to more sophisticated technology such as distributed objects like COM and CORBA. Web services, albeit a newer standard approach, work much like "traditional" distributed objects. In other words, it's an evolution, not a revolution.
Myth Number Two: You must use Web services to build an SOA. Nope. While Web services are by far the preferred enabling standard in the construction and deployment of a SOA, you can certainly build SOAs using other standards-based technology such as CORBA, COM, and J2EE. You may even build SOAs using technology that's proprietary to you. Remember, SOAs are all about the sharing and management of services, as well as processes/orchestrations that exist on top of those services. The technology you employ should be appropriate for your requirements. Myth Number Three: If you purchase an ESB, you have a SOA. Not really. ESBs are very powerful technology, they allow you to move information in and between applications, and do so through Web service interfaces. However, they are not good at behavior-based integration, or sharing of actually application behavior, they are more information-oriented. Thus, while they can certainly be part of a SOA, they are not really a "SOA-in-a-Box" solution.>> Mr. Linthicum seems to have the ability to generate a certain amount of controversy.
