AWS Automated Cost Optimizer

📌 Overview

This project automatically reduces AWS cloud costs by stopping unused EC2 instances using serverless automation.

It uses AWS Lambda and EventBridge Scheduler to monitor and control EC2 usage without manual intervention.

---

🎯 Objective

To minimize unnecessary AWS spending by automatically shutting down idle or selected EC2 instances.

---

🧰 Technologies Used

• AWS Lambda
• Amazon EC2
• Amazon EventBridge Scheduler
• Python (Boto3)

---

⚙️ How It Works

1. EventBridge Scheduler triggers the Lambda function at a fixed interval
2. Lambda scans running EC2 instances
3. Matches the target instance
4. Stops the instance automatically
