CTO Forum: BEA exec hails service-oriented architectures; Web services, messaging play roles.

Boston-- Service-oriented architectures leveraging messaging and Web services are key to meeting complicated system integration needs, a BEA executive stressed during a keynote presentation at the InfoWorld CTO Forum conference here on Tuesday.

BEA'sAdam Bosworth, chief architect and senior vice president of advanced development at the San Jose, Calif.-based company, said enterprises are dealing with hundreds or even thousands of applications that have difficulty communicating with each other. "A very large number of applications have been built, and unfortunately, the people who built them are long gone," Bosworth said.

Integration, he said, requires three phases: integrating the UI, integrating data, and integrating business processes. "This little problem, succinctly put, is you're being asked to do three things simultaneously" that cannot be done, said Bosworth.

"We have to change the applications more rapidly, we can bring them down less and less and we have fewer developers to do it. This represents a bit of a challenge," he added.

Standardization and flexible, service-oriented architectures are needed to address pressing integration issues, according to Bosworth. "The issue is, if you want an architecture that's going to work, it has to work even when the implementation's changing," he said. He cited the Cullinet database as an example of a formerly industry-leading technology that faded away because it did not adapt to changing technology conditions.

He also cited instances of customers having problems using new technologies and moving 2,000 to 3,000 messages per second in their backbones and enterprises universally needing to run multiple OSes. "BEA has made a bet; the bet was that Web services are, if you will, the unlocking key for integration in the face of these realities," Bosworth said.
