I came across this article, “Making Legacy Applications Flexible,” by Mike Vizard on his blog, “The Future of IT Architecture”. Mike gives a great example of the benefit of reusing legacy applications through service-enablement. The blog highlights a legacy modernization solution that Scotia Bank pursued and does a nice job of highlighting the benefits of allowing legacy assets to transparently partake in the broader enterprise needs.
Scotia Bank, dependent on a set of Mainframe-based IMS applications, found that it could retain its applications and still move the bank forward to meet its daily needs. It did this by applying one of many service-enablement approaches available on the market.
A few quotes from Vizard’s article capture the essence of the benefits,
“… Scotia Bank is now able to leverage years of investments in IMS applications and expertise that would be almost impossible to replicate.”
“it’s exactly that kind of flexibility, coupled with some prudent economics, that business executives, as noted in a recent global CIO study, have been demanding from their IT departments even long before the downturn.”
This is what we continuously see in our Verastream engagements, service enabling legacy applications give you the ability to keep current while leveraging what you have — meet your daily demands without the need to rebuild core applications.
