Simple Notes App ( Dockerized Deployment Project)

This project is a containerized full-stack Notes Application designed to demonstrate practical deployment skills using Docker and Nginx on a cloud virtual machine.The application runs as a multi-service system and is accessible through a reverse proxy setup, simulating a real-world production deployment environment.

System Architecture

The application consists of the following components:

• Frontend (React)
• Backend Service (Python-based API)- 3.9 version
• Reverse Proxy (Nginx)
• Docker-based container runtime environment
• AWS EC2 instance for deployment

Request Flow
