Software modernization is the process of upgrading legacy systems to modern, scalable, and efficient technologies to enhance performance, security, and user experience. It involves refactoring, re-platforming, or completely rebuilding outdated applications to align with current industry standards and business needs. By adopting cloud computing, microservices, and modern programming frameworks, companies can improve agility, reduce maintenance costs, and future-proof their software. Modernization not only enhances operational efficiency but also ensures seamless integration with emerging technologies, enabling businesses to stay competitive in an ever-evolving digital landscape.
