Automating Cloud Cost Optimization: How to Automatically Clean Up Idle AWS Resources

Описание и применение

Автоматизированный процесс очистки неактивных ресурсов AWS (EBS‑тома, Elastic IP) с помощью EventBridge, Lambda и SSM, который еженедельно сканирует аккаунт, создает снимки и удаляет ресурсы, снижая расходы и повышая безопасность.

Задача

Idle AWS resources such as unattached EBS volumes, obsolete EC2 instances, and abandoned Elastic IPs consume budget without providing value.

Результат

Weekly automated cleanup of idle EBS volumes and Elastic IPs, with snapshot safety and optional dry‑run logging, cuts unnecessary cloud spend and reduces attack surface.

Рабочий процесс

• Schedule EventBridge cron job every Friday at 6:00 PM
• Trigger Lambda function to scan for unattached EBS volumes and idle Elastic IPs
• For each idle resource, invoke SSM Automation Document to snapshot and delete the resource

Доказательства

With over 12 years in IT and 6+ years managing production workloads on AWS, I’ve found that the best way to control cloud spend is to shift from reactive monitoring to automated remediation.

Источник

An AWS Lambda function scans the account for unattached EBS volumes and idle Elastic IPs.

Источник

If an idle resource is found, Lambda triggers an AWS Systems Manager (SSM) Automation Document to snapshot the volume for safety and then delete it.
