Application modernization refers to the process of updating, transforming, or re-architecting existing legacy applications to leverage modern technologies, architectures, and development practices. The goal of application modernization is to enhance the functionality, performance, scalability, security, and user experience of legacy applications, while also reducing maintenance costs, simplifying management, and aligning with evolving business needs.
Modernization can involve a range of approaches, including re-hosting, re-platforming, refactoring, and rebuilding. Re-hosting involves moving an application from one platform or environment to another without making any significant changes to the application’s code or architecture. Re-platforming involves migrating an application to a different platform that provides more modern capabilities or features. Refactoring involves modifying the existing code to improve its structure, maintainability, and performance. Rebuilding involves redesigning and redeveloping the application from scratch using modern architectures and frameworks.
Application modernization is important for organizations that rely on legacy systems that are becoming outdated, costly to maintain, and incompatible with modern technologies. By modernizing their applications, organizations can improve their agility, competitiveness, and innovation, while also reducing technical debt and operational risk.
