CloudScale DevOps Infrastructure on AWS

A full-stack cloud-native DevOps project built on AWS using Docker, Nginx, PostgreSQL, Node.js, GitHub Actions CI/CD, and Application Load Balancer (ALB).

This project demonstrates real-world DevOps concepts including containerization, reverse proxy configuration, CI/CD automation, cloud deployment, load balancing, persistent storage, and full-stack authentication architecture.

🔐 Authentication

The project includes a fully functional authentication system:

• Frontend Login Page
• Backend API Validation
• PostgreSQL Database Verification
• Success and Invalid Credential Handling

---

🚀 CI/CD Workflow

1. Code pushed to GitHub
2. GitHub Actions pipeline triggered
3. Application deployed to AWS EC2
4. Docker containers rebuilt and restarted
5. Updated application served through Nginx and ALB

---

📦 Docker Services

• Frontend Container
• Backend API Container
• PostgreSQL Database Container

---

💾 Persistent Storage

PostgreSQL database persistence is configured using Docker Volumes to prevent data loss during container restarts.
