Selection of a system architecture for deployment of a web application is always a crucial decision as lots of planning and implementation involves. As monolithic architecture offers a simpler and more straightforward approach and better results for a small-scale approach whereas microservices architecture would be an expensive approach. In addition, monolithic architecture gives satisfactory results compared to microservices architecture while having low traffic. However, the error percentage of monolithic architecture is extremely high while having heavy traffic whereas microservices architecture handles heavy traffic with a very low error percentage. This research paper explores the relative merits of monolithic and microservices architecture for E-Commerce web applications, using Express JS and Node JS as the primary technologies. The study provides a comprehensive examination of the two architecture patterns and employs a practical approach to demonstrate the differences. The architecture is compared based on metrics such as latency, throughput, response-time, error percentage and cost. The findings indicate that when it comes to large and complex applications, microservices architecture outperforms monolithic architecture in terms of scalability and reliability. The appropriate choice of architecture pattern should be determined by the unique needs of the project. The objective of this research is to evaluate the monolithic and microservices architectures for an ecommerce use case, and to propose guidelines for small- and large-scale enterprises on which architecture to implement.
