Filter Out and Delete Old AWS EBS Snapshots
This runbook identifies and removes old Amazon Elastic Block Store (EBS) snapshots. By setting a specific age threshold it scans through designated AWS regions, pinpoints snapshots that surpass the age limit, and subsequently deletes them. This operation not only ensures efficient resource utilization but also aids in minimizing storage costs, promoting a cleaner and more cost-effective cloud environment.

Filter Out Old AWS EBS Snapshots
There was a problem that the LLM was not able to address. Please rephrase your prompt and try again.This task identifies old Amazon Elastic Block Store (EBS) snapshots. By setting an age threshold, it scans across specified AWS regions, highlighting snapshots that exceed the set duration. This facilitates better management, paving the way for timely deletions and efficient storage utilization.
