Filter out EBS Volumes attached to stopped EC2 instances

This is a task focused on identifying Elastic Block Store (EBS) volumes that are connected to Amazon EC2 instances currently in a stopped state by examining the instance-state and corresponding volume mappings.

Detach and Delete AWS EBS Volumes
There was a problem that the LLM was not able to address. Please rephrase your prompt and try again.
This task involves the removal of Elastic Block Store (EBS) volumes from their associated instances followed by the deletion of these volumes. In this particular task detachment and deletion of EBS volumes is related to stopped EC2 instances. It is executed to free up storage resources, enhance resource allocation efficiency, and optimize costs within the AWS infrastructure.
