The acclaimed essayist and novelist Nora Ephron once said, "What my mother believed about cooking is that if you worked hard and prospered, someone else would do it for you." Nothing could better capture the spirit of service-oriented architectures (SOAs) than this statement from a person who clearly does not consider cooking a core competency. Translated to human terms, an SOA can help make sure that the right person is doing the cooking at the right time. The idea of a service-oriented architecture is simple, and much older than any Web services standard. Instead of services being statically bound to each other in some sort of "hard-coded" relationship (which is often the case for many real-world Web service deployments today), in an SOA, service consumers can discover the service providers that they need and use them as required. Typically, information about the... (more)

Although it's not uncommon to find competing specifications and standards in the world of Web Services, this time we shouldn't be forced to make an exclusive choice because WS-ResourceFramework and WS-Transfer can serve compliment...

Governance, Security, and Management in a Service-Oriented World - When New and Old Collide

Significant investments in the successful management and administration of many critical business systems have had mixed success over the years. In a new, more competitive age of regulation and globalization, SOA promises much in terms of business agility and efficiency, but how do we maintain visibility, control, and appropriate governance of this new and much more highly distributed service-oriented world? Most authorities in this field agree that management and security are complimentary foundations of an essential framework for SOA success, but what does that really mean and ... (more)

SOA World Cover Story — Are You Being Served?

"A child of five would understand this. Send someone to fetch a child of five." - Groucho Marx  People have begun to understand that a properly implemented SOA has the potential to improve business agility and adaptability to changing business conditions, but we're still suffering from at least one innate prejudice common to IT folks. That prejudice comes, in part, from our own fascination with the technology we use. Perhaps we need to view the goals and challenges that SOA brings with the same simplicity that small children selling lemonade from a box on the sidewalk have for a... (more)
