Legacy Systems in the Age of Big Data: Modernization Strategies

Vijayasekhar Duvvur

Abstract: In the contemporary digital landscape, legacy systems often hinder the optimal utilization and analysis of big data. This paper explores the challenges and strategies involved in modernizing legacy systems to leverage big data effectively. It addresses key issues such as system interoperability, scalability, and data integrity in the context of modernization. We propose a systematic approach to modernize legacy systems, incorporating cloud computing, microservices, and data lakes, to enhance data-driven decision-making capabilities.
