Application modernization is the process of modernizing legacy software programs to increase performance, scalability, and security by integrating them with new technology. This could entail reworking, replat forming, or altogether redesigning legacy systems to make them compatible with cloud environments, microservices, and APIs. Modernizing systems improves productivity, minimizes technological debt, and allows businesses to stay competitive by exploiting new features and providing improved user experiences. It allows for easier connection with other current systems, boosts agility, and assures that firms can scale and develop more efficiently.
