Challenges and Solutions in Migrating Legacy Retail Systems to Aws Cloud: A Comprehensive Review
Downloads
This paper presents a comprehensive study on the automatic migration of legacy retail systems to AWS cloud infrastructure, extending beyond existing research by addressing both technical and strategic challenges. Unlike prior work that mainly focuses on migration strategies, this study explores how AWS-native tools and Infrastructure as Code (IaC) patterns enable automation throughout the migration life cycle. Drawing insights from nearly 40 industry and research sources, it highlights how advanced AWS automation enhances scalability, security, and business resiliency. The work emphasizes resolving compatibility and data integrity challenges through incremental, risk-based deployments supported by automated verification and rollback mechanisms. Case studies illustrate how automation reduces downtime, mitigates human error, and accelerates time-to-market for retail businesses. The research introduces new variables and best practices that help retailers not only migrate legacy systems but also future-proof their IT environments, offering a refined blueprint for cloud adoption that sets a new standard in retail digital transformation.
