IDC PlanScape: Application Modernization Approaches

Description

This IDC PlanScape explores the common approaches to application modernization that prepare organizations against impending risks and allow them to adapt to emerging technologies. Application modernization is no longer a choice but a necessity for organizations aiming to reduce risks, improve efficiency, and maintain competitive positioning. By embracing cloud technologies and modern development practices, CIOs can transform legacy applications into strategic assets that drive long-term value for their organizations.According to Gerald Johnston, adjunct research advisor with IDC's IT Executive Programs (IEP), "Application modernization is not just about migrating to the cloud; it's about strategically transforming legacy systems to unlock scalability, agility, and innovation. Whether through re-factoring, rewriting, or rehosting, the ultimate goal is to align IT capabilities with evolving business demands while future proofing for emerging technologies."
