Of the 300 organisations surveyed for the analyst firm’s Modernising Legacy Applications: Maximising the Investment report, more than 90% said that modernising legacy applications was a long-term, strategic initiative.
“IT is under intense pressure from business units to deliver applications that provide new ways to look at old processes and data,” said Perry Donham, director of enterprise integration research at Aberdeen Group.
“We found that the companies that are keeping up with these demands while lowering their overall costs for maintaining legacy applications are leaving the applications in place and building services-based interfaces on top of the underlying packages and data,” he added.
Companies that deploy services layers on the mainframe to expose legacy packages typically achieve a 60% reduction in the cost of legacy application maintenance, versus an average 30% decrease from other approaches, said the report.
However, Aberdeen group said business agility, not cost, was the main driver for the most successful organisations that are working on legacy modernisation projects.
