Filter ASGs: Identify ASGs where both the desired capacity and minimum size are zero.

This task filters ASGs to identify those with both desired capacity and minimum size set to zero involves checking Auto Scaling Groups to find inactive configurations. This process helps in identifying ASGs that are not currently scaling any instances, potentially leading to cleanup actions to optimize resource usage and reduce costs in AWS environments.

Delete AWS EC2 Auto Scaling Groups (ASGs)
There was a problem that the LLM was not able to address. Please rephrase your prompt and try again.
This task involves removing specified ASGs from the AWS environment. This operation is critical for cleaning up unused or unnecessary resources, managing costs, or decommissioning services.
