Building Security into a Service-Oriented Architecture
Service-oriented architectures (SOAs) based upon Web Services are an evolutionary improvement upon existing IT architectures, primarily because these SOAs offer loose coupling between Service producers and consumers. Loose coupling refers to a level of independence between the participants in a Web Services interaction that allows them to interact on their own terms, without requiring substantial changes on one system when the other changes. Such loose coupling enables an enterprise’s IT infrastructure to be agile in the face of change. Loose coupling, however, while simple to understand, is complex to implement. There are many requirements facing an enterprise’s IT infrastructure that threaten the loose coupling of its architecture, and the most significant of these is security. Because fundamental security principles require a Service to authenticate a consumer, the Service and its consumer run the risk of being tightly coupled, unless the security itself can be handled in a loosely coupled fashion.

ZapThink: Report Shows Web Services-based Process to Displace Integration Solutions / Implementing Service-Oriented Process Key to Meeting Business Agility Requirements
ZapThink: Report Shows Web Services-based Process to Displace Integration Solutions Implementing Service-Oriented Process Key to Meeting Business Agility Requirements (View More Information…) WALTHAM, MA, April 16, 2003 — As enterprises apply Service-oriented architecture principles to business process management and automation, they will find that such “Service-Oriented Process” solutions will supplant the need for today’s integration solutions, concludes a report published today by ZapThink, LLC, an analyst firm focused on XML, Web Services, and Service-oriented architectures. The report concludes that Service-oriented process tools enable business users to assemble business-oriented Web Services into business processes that are themselves exposed as Web Services. “The success of business depends upon IT systems that are able to deliver functionality that meets business requirements in a flexible, agile way,” explains Ronald Schmelzer, senior analyst at ZapThink, “Yet most corporate IT infrastructures are littered with a heterogeneous array of…

The Business Case for Web Services
Today’s IT executive doesn’t have the time or the budget to invest in new technologies that fail to offer rapid business value. It is important, therefore, for managers to understand both the short-term and long-term value of Web Services. They must be able to cut through the hype surrounding this new approach to computing and understand how their organizations can use Web Services today to reduce the cost of integration in the enterprise. Even more important, however, they must understand the strategic value of Web Services.The strategic value that Web Services offer is in the form of business agility: IT infrastructures flexible enough to enable companies to leverage changing business environments for competitive advantage. To build such agile infrastructures, organizations must build Service-oriented architectures, leveraging Web Services strategically across their IT environment. Service-oriented architectures, while easy to conceive in theory, are difficult to build in practice. Companies should take a…

2002 Retrospective and Thinking Ahead
Maybe it’s the end of the year that brings retrospective thought, or perhaps it’s one too many post-holiday feast chats over eggnog, but in any case, it is the habit of many an analyst and journalist to think through all the events of the previous year and guess how the upcoming year will turn out. So, we thought we’d throw our hat into the ring and tie together some of the major events of 2002 with a few unique twists from our distinct perspective while also providing clues as to where our research, analysis, and insight will be heading. The emergence of SOAs in corporate IT infrastructures 2002 brought Web Services into the mainstream of IT industry thought, as well as into limited production in many enterprises of different sizes and industries. Many of these tentative first steps were limited implementations of tightly coupled, synchronous, SOAP over…
