 About the author
Advanced service-orientation
The pages published on this site cover the fundamentals of common service-orientation principles. These can be used to design and standardize individual services.

However, the true power of service-orientation is realized when these concepts are applied to SOA as a whole. This is when key characteristics of contemporary SOA can be realized, such as service-oriented business modeling, the creation of coordinated service abstraction layers, and enterprise-wide loose coupling.

These and other aspects of SOA and service-orientation are covered in

Opinions

Service orientation is a philosophy rather than a product or a technology. Using web services does not necessarily mean that your application is service oriented. Web services specifications and supporting technology can be used as glue for ‘traditional’ distributed systems in ways that aren’t very service-oriented.
