Sample E-Commerce application using Microservices / Cloud Native Architecture (CNA)

A fictitious e-commerce sample application built using modern technologies and Microservices & Cloud Native Architecture patterns.

• Polyglot Languages & Frameworks (Java - Spring Boot/Cloud, Python - FastAPI, SQLAlachamey, JavaScript/TypeScript - Node, ExpressJS, React)
• Polyglot Databases (MongoDB, Redis, ElastiSearch, PostgreSQL)
• Able to deploy to local Kubernetes (k8s) cluster as containers (Docker) and also to Public Cloud (AWS).

This is an end-to-end e-commerce solution that demonstrates how to build a moder CNA application using microservices architecture with full-stack technologies. This application includes below functional microservices which are independently deployable with bounded context.

You can standup application locally on your laptop/desktop with few steps and also to AWS.
