Question

A CloudOps engineer needs to automatically delete Amazon EBS snapshots older than 30 days across a production account every night at 02:00 UTC. The solution must be serverless, require minimal custom code, and use AWS-native automation runbooks where possible. Which approach best meets these requirements?

Accepted Answer

Create an EventBridge rule with a cron-based schedule that targets an AWS Systems Manager Automation runbook configured to identify and delete snapshots older than 30 days.

Answer

Configure an Amazon CloudWatch alarm on EBS snapshot count that triggers an SNS notification to an operations team to manually delete old snapshots.

Answer

Enable Amazon Data Lifecycle Manager with a policy, but manually run a Lambda function each morning to catch snapshots the policy missed.

Answer

Create an EventBridge rule that matches CreateSnapshot API events in CloudTrail and immediately deletes any snapshot older than 30 days.
