Abstract

The rapid expansion of online retail has made scalability, flexibility, and resilience essential for e-commerce platforms. Traditional monolithic architectures often struggle to meet these demands, leading to the widespread adoption of microservices architectures. This research paper explores the principles, design strategies, and best practices for building scalable microservices architectures tailored to e-commerce. It covers service decomposition, API gateways, service discovery, event-driven communication, distributed data management, security, observability, and real-world case studies. The paper concludes with recommendations and future directions for developing robust, scalable e-commerce platforms.
