☁️ Cloud Infrastructure Project (Terraform + AWS)

📌 Overview

This project provisions a complete cloud infrastructure on AWS using Terraform.

Instead of manually creating resources, we use Infrastructure as Code (IaC) to automate deployment. This makes the system scalable, secure, consistent, and easy to manage.

🧠 Architecture Summary

The system includes:

• VPC (Virtual Private Cloud) – Network infrastructure
• Public & Private Subnets – Security separation
• EC2 Instances – Application servers
• Auto Scaling Group (ASG) – Automatic scaling
• Application Load Balancer (ALB) – Traffic distribution
• RDS – Managed database
• S3 – File storage
• IAM – Access control
• CloudWatch – Monitoring

---

🔄 System Workflow

1. User sends request to the application
2. ALB receives the request
3. ALB forwards it to EC2 instances
4. EC2 processes the request
5. Data is stored/retrieved from RDS
6. Files are stored in S3
7. CloudWatch monitors system performance
