A practical e-commerce platform with Spring frameworks, Kubernetes, Terraform and deployed on AWS EKS. The repository demonstrates microservice patterns and cloud-native capabilities with focus on scalability, security, resiliency, observability, infrastructure automation and deployment improvements.

💡 This application is not business oriented and my focus is mostly on technical part, I just want to implement a sample app from scratch with microservice architecture using different technologies, principles and patterns.

🌀 This Application is in-progress and I will add new features over time. 🌀
