Overview

Cloud Notes Platform is a modern cloud-native notes management web application developed using containerized deployment architecture and public cloud infrastructure.

The application allows users to:

• create notes
• store notes persistently
• manage lightweight note workflows
• access the application securely over HTTPS

The system is designed using a multi-component architecture consisting of:

• Flask backend application
• PostgreSQL database
• NGINX reverse proxy

The application is deployed on an AWS EC2 virtual machine using Docker Compose orchestration and HTTPS reverse proxy configuration.

The project demonstrates practical cloud deployment concepts including:

• containerization
• reverse proxy configuration
• persistent storage
• automated deployment
• cloud-hosted infrastructure
• HTTPS certificate management
• environment-based configuration
