🚀 CloudNative DevOps Blueprint

A comprehensive DevOps blueprint for deploying cloud-native applications with enterprise-grade tooling

🎯 Overview

This project demonstrates a production-ready DevOps pipeline for deploying a MERN (MongoDB, Express, React, Node.js) application using modern cloud-native technologies and best practices. From local development to cloud deployment, this blueprint covers the entire application lifecycle.

📦 Application Versions

Three versions of the application are available, each with distinct visual and functional differences:

Version	Frontend	Backend
1.0.0	🔵 Blue theme	v1.0.0
2.0.0	🔴 Red theme	v2.0.0
3.0.0	🟣 Purple theme	v3.0.0

See src/README.md for screenshots and build instructions.
