Representational State Transfer, commonly known as REST, is a style of distributed software architecture that offers an alternative to the commonly accepted XML-based web services as a means for system-to-system interaction. Many of you know me as one half of the ZapThink team – an ad...
Instead of thinking of Web Services as a collection of interfaces to software functionality that must somehow be made to connect to other such interfaces, enterprises should approach Web Services as enabling a fundamentally process-driven architecture that leverages distributed process...
Content is information that is intended for human consumption, as opposed to "data," which are information intended for machine or system use. At times, we use other words such as knowledge, semantics, and intellectual assets to describe content. What differentiates human-oriented cont...
Are implementations of Web Services simply "old wine in new bottles," with interfaces every bit as brittle and tightly-coupled as in the past, or are they really implementing Service-Oriented Integration among Services at many levels of granularity? Clearly, "Web Services Integration" ...
Over the past two years, governments around the world have caught the enterprise architecture and SOA fever. This is especially the case in the US Federal Government, where a number of regulations, EA frameworks, and major spending initiatives are all pointing towards continued and las...

Reducing the cost of IT management is one of the primary pressures for most organizations. One of the most common ways to reduce such costs is to enable the reuse of applications that developers have already created and configured for the enterprise. In the past decade, especially in t...
As we predicted earlier in the year, cloud computing is starting to take hold, especially if you believe the marketing literature of vendors and consulting firms. Yet, we are seeing an increasing number of Cloud success stories, ranging from simplistic consumption of utility Services a...
