Legacy Modernization
Today, Customers whose applications reside on legacy IT infrastructure are facing increasing pressures as the result of a declining skilled-resource base, high cost of ownership, and a lack of flexibility to leverage new and emerging technologies. Customers are facing challenges in extracting maximum utility from their legacy infrastructure and in optimizing their application portfolio to keep pace with business demands. Dynamic business environments and the need to collaborate with partners, suppliers, and customers call for modernization of legacy applications for higher agility and flexibility.
Over 70% of the world's active business applications run on legacy platforms like mainframe and AS/400. Customers run mission-critical applications/transactions on these platforms and the replacement cost of these business applications is estimated at an unviable $20 trillion. Moreover, recent technological investments and advancements on these legacy platforms, from vendors like IBM, have made it imperative for the customers to either maintain and modernize the legacy platforms or migrate to new platforms, based on requirements.
