In the first article in this series (Vol. 4, issue 9), I described some of the middleware requirements necessary to support a full-function service-oriented architecture (SOA), and introduced the role of the enterprise service bus (ESB) in meeting those requirements.
The current slate of Web services standards has evolved into a mature set of very useful API's and into service-oriented architectures, or SOAs. Enterprise integration, however, includes many requirements that are not met by SOAs alone. A movement is under way to augment Web services w...
We've been covering Web services technologies for quite some time now, almost three years. In that time - I think it amounts to two eternities in Internet time - we've seen all sorts of interesting things occur. Cooperation, coopetition, even the creation of a group whose sole purpose ...
'When change within your organization is slower than that without, you're in real trouble. We can't predict the future, but we can learn to react a lot faster than our adversaries.' - Jack Welch
UDDI (Universal Description, Discovery, and Integration) is fast becoming a standard for storing business processes available on the Web. Although UDDI is capable of storing many different types of data, for the purposes of this article I'll focus on how UDDI can be used to register We...
Mention the word 'compliance' and it is likely to conjure up images of scandalous performance by companies such as Worldcom, Enron, and Tyco. But beyond corporate governance and government regulations such as Sarbanes-Oxley, HIPAA, and the National Do Not Call Registry, compliance is c...
Business is becoming increasingly virtual and decentralized, while real-time management of relationships with employees, contractors, partners, suppliers, and customers is becoming ever more crucial. Even within a single company, applications may reside on different platforms, in separ...
There is a need for container-managed support for local invocations among colocated Web services. This feature would be similar to EJB local invocations in the J2EE world.
According to the latest Web services 'hype cycle' from Gartner, both Web services security standards and the deployment of Web services with security are rushing headlong into the dreaded 'Trough of Disillusionment.' This means that the greatest levels of hype in these areas are suppos...
Software design has always been a focus for developers, but as we cycled through different approaches, standards, and architectures over the years, I think we've had a tendency not to pay enough attention to the fundamentals of software engineering. Clearly I've seen a decline in softw...
Implementing industry standards for business processes can do far more than provide a common protocol for operations. Once commodity information or documents are standardized, it makes sense to look at what common actions need to be taken on that data or document - and standardize thos...
Security is important. Anyone in the business of designing, developing, hosting, or managing business applications understands this fundamental statement. Web services present unique challenges such that the integrity and security of the content of the exchanged documents is just as im...
There's a common misconception that Business Process Execution Language for Web Services (BPEL) is useful only if all of your systems are Web services. This article describes how Web Services Invocation Framework (WSIF) enables BPEL to orchestrate nearly any legacy system as if it were...
We're all familiar with the Gartner 'hype cycle,' we've experienced the roller coaster ride it describes as we've worked to move a new technology towards becoming relevant. Web services has been evolving for approximately 36 months, and many already claim victory. However, while there'...
