Implementing DevOps in E-Commerce System for Continuous Delivery

Abstract: Modern software systems need to be scalable, deploy quickly, and offer strong visibility. Traditional monolithic applications struggle to meet these needs because they are tightly connected and complicated to deploy. This work introduces a cloud-native microservices-based e-commerce platform made with Docker, Kubernetes, and DevOps CI/CD automation. It has full visibility through Open Telemetry, Prometheus, and Grafana. Each business service—Product Catalog, Cart, Checkout, Payment, Shipping, Email, and Recommendation—is independent and deployed separately. Kubernetes handles load balancing, scaling, and self-repair. GitHub Actions automates the CI/CD pipeline for testing, building, and deploying. Visibility tools offer distributed tracing, metrics, and logs for debugging and checking performance. Experimental results show faster deployment speeds, lower latency, and better traceability across services.
