Enterprise application modernization is the process of updating your existing legacy application’s platform infrastructure, architecture, framework, language, and/or features to meet your current business needs. This process involves migrating applications and data to new platforms, modernizing the application architecture, improving the user experience, and integrating the application with other systems and technologies. It can also involve replacing legacy systems with new off-the-shelf software or new custom applications. It doesn’t replace or discontinue your entire system. Instead, it utilizes the latest technologies to increase the existing system/platforms’ life span. While it could be time-consuming, complex, and expensive, modernizing legacy systems is worth the investment.

The application modernization process usually involves the discovery, design, and implementation phases. However, moving to the cloud is more complex and goes beyond the simple upgradation of apps. It includes modernizing the tech stack to make your applications more scalable and flexible.

The main goals of enterprise application modernization are to improve the application’s functionality, reduce maintenance costs, increase scalability, enhance security, and streamline business processes. By modernizing legacy applications, organizations can increase their competitiveness, improve operational efficiency, and better meet the needs of their customers.
