This paper explores the transformative journey of e-commerce architectures, tracing the evolution from legacy ATG systems to contemporary cloud-native solutions. Initially designed to support traditional, monolithic e-commerce platforms, ATG architectures were limited in their ability to scale and rapidly adapt to shifting market dynamics. As consumer demands and technological advancements intensified, businesses sought more agile and resilient frameworks to sustain growth. Cloud-native architectures have emerged as the preferred solution, characterized by modular microservices, containerization, and automated orchestration, which together enable continuous integration and deployment. This shift has allowed enterprises to achieve improved scalability, reduced operational costs, and enhanced flexibility in responding to competitive pressures. The study analyzes key drivers behind this evolution, including the need for real-time analytics, personalized customer experiences, and robust security measures. By examining case studies of successful migrations from ATG to cloud-native platforms, the paper highlights significant improvements in system performance, reliability, and user engagement. Additionally, it discusses the challenges faced during this transition, such as legacy system integration, data migration complexities, and cultural shifts within IT departments. The findings underscore the strategic importance of embracing cloud-native architectures to future-proof e-commerce operations. Overall, the research offers a comprehensive framework for understanding the interplay between traditional e-commerce systems and innovative cloud technologies, setting the stage for future developments in digital commerce and establishing a roadmap for organizations seeking to modernize their technical infrastructure. In summary, this investigation provides vital insights into the technological and business imperatives driving the modern transformation of e-commerce systems. These insights foster innovation.
