This project is a serverless solution designed to reduce AWS infrastructure costs by automatically identifying and deleting orphaned resources. Using Python and the Boto3 SDK, the system scans for unused EBS volumes and unassociated Elastic IPs, terminates them, and sends a summary report via email.
- Automated Cleanup: Removes EBS volumes in 'available' state and unassociated Elastic IPs.
- Event-Driven: Scheduled via Amazon EventBridge for hands-free maintenance.
- Real-time Alerts: Integrates with Amazon SNS to provide instant email audit trails.
- Infrastructure as Code (IAM): Implements secure access policies for cross-service communication.
- Language: Python 3.12
- AWS SDK: Boto3
- Compute: AWS Lambda
- Scheduling: Amazon EventBridge
- Messaging: Amazon SNS
- Logging: Amazon CloudWatch
This project was successfully tested and validated with the following evidence:
- Scheduled Execution: Log streams confirm the automation fired successfully at 10:35 UTC.
- Cleanup Success: Verified the deletion of 1GB test volumes and the release of Elastic IPs.
- Notification: Confirmed receipt of "AWS Cleanup Alert" email via SNS.
