The requirement is to create automation that deletes unattached EBS volumes that have been

unattached for 14 days. To do this, the DevOps engineer needs to use the following steps:

Create an Amazon CloudWatch Events rule to execute an AWS Lambda function daily. CloudWatch

Events is a service that enables event-driven architectures by delivering events from various sources

to targets. Lambda is a service that lets you run code without provisioning or managing servers. By

creating a CloudWatch Events rule that executes a Lambda function daily, the DevOps engineer can

schedule a recurring task to check and delete unattached EBS volumes.

The Lambda function should find unattached EBS volumes and tag them with the current date, and

delete unattached volumes that have tags with dates that are more than 14 days old. The Lambda

function can use the EC2 API to list and filter unattached EBS volumes based on their state and tags.

The function can then tag each unattached volume with the current date using the create-tags

command. The function can also compare the tag value with the current date and delete any

unattached volume that has been tagged more than 14 days ago using the delete-volume command.
