“I specialize in legacy evolution.” That’s how renowned Gartner Research Director Dale Vecchio introduced himself to viewers of the ebizQ webinar, “The Integration Continuum: Host Extension To Programmatic Integration.”
And he went on to outline just that: the evolution of computing from what Vecchio calls “online paper,” the simple representation on-screen of text and graphics, to a phase in which people use technology to help them make better decisions, to the current phase, which Vecchio dubs Phase Three and describes as using IT to interact in “uncontrolled, un-uniform and, in some cases, unstable environments.”
In giving his overview of the evolution, and in a consistently reassuring manner, Vecchio repeatedly makes clear that the struggles of companies to integrate and extend their legacy systems to make them useful in an age of real-time enterprises and of sharing information with partners, suppliers and customers is part of the natural order of things in the world of IT. He puts those struggles in perspective, and gives glimpses of where he sees things heading.
“I normally talk to clients who have one foot in the Old World and one foot in the new one,” Vecchio says. “And they’re trying to figure out which leg to lean on. And many times it appears they’re doing the polka, going from the old systems to the new ones. All these organizations face the same problem: the technical possibilities the Internet brings, the opening up of access to vast amounts of information in an organization.
“On the other hand,” Vecchio continues, “they have a large install base of systems that work pretty well. So they’re trying to figure out how can to balance these systems that’ve been built to run for quite a few years, with these news requirements to externalize access to these systems, to connect with business partners.
“These Phase Three systems aren’t really replacements for any of these Phase One or Two systems, they’re additive, and that’s the challenge. They’re on top of these other systems we have in place.
“And that,” Vecchio stresses, “is what the legacy integration continuum is all about. There’s a series of solutions, some fairly simple and straightforward, and some more complicated. But it’s a continuum. There’s no one answer.”
The challenge, he says, is formidable, especially if quality of service to users is to be maintained. “These external constituents, these users of these Phase Three solutions really have different expectations. They want to collaborate with minimal or no restrictions. They want to buy and sell things. They want a customized and personalized experience. And they want anywhere, anytime connections. And they want it to be fast.
