This real-time data processing is crucial for retailers who need to manage inventory, track shipments, and adjust to market changes quickly. With edge computing, retailers can get immediate insights into their supply chains, enabling faster and more accurate decision-making. The article reviews current research and case studies to illustrate the benefits of edge computing in retail. These benefits include better inventory management through real-time updates, more personalized and engaging marketing campaigns, and increased efficiency in logistics by automating processes. Edge computing also enhances the in-store experience with technologies like augmented reality, which can boost customer interaction and satisfaction. However, adopting edge computing also comes with challenges, such as high implementation costs, the complexity of integrating new systems, and concerns about data security. The article addresses these challenges and provides strategies for overcoming them, offering practical advice for effectively using edge computing. In summary, the article argues that edge computing will be a vital factor in retail’s future success and innovation. By making supply chains more agile, responsive, and efficient, edge computing helps retailers meet market demands and stay ahead of the competition. As technology continues to evolve, the role of edge computing in improving supply chain resilience and transforming retail marketing will become even more significant.
