Mainframe environments have long been the platform of choice for mission-critical business applications, but they are unlikely to remain so. A Standish Group survey shows that 70% of CIOs consider that the mainframe provides a central, strategic role today. In 5-10 years the picture will be very different, with none seeing it as a strategic platform.
Migrating applications to more contemporary platforms is a proven modernization strategy that reduces costs and makes IT more agile in supporting business going forward. By replicating the mainframe infrastructure on lower-cost platforms, including cloud platforms, applications deliver more value for a fraction of the cost of rewriting or replacing them with off-the-shelf packages.
