Description

This policy identifies AWS Elastic Load Balancers that are considered idle, including Application Load Balancers (ALBs) and Classic Load Balancers (CLBs). A load balancer is classified as idle if it has processed zero requests (that is, the RequestCount metric equals 0) over a 30 days period.

Rationale

Idle load balancers continue to incur hourly charges even when they are not serving traffic. Identifying and decommissioning unused ALBs and CLBs helps reduce unnecessary costs, improve resource hygiene, and optimize overall AWS spending.

Audit

This policy applies only to Application and Classic Load Balancers.

AWS Elastic Load Balancer is flagged as INCOMPLIANT if its 1-Month Request Count metric is less than or equal to 0.

An ELB is marked as INAPPLICABLE if its Created Time is less than 30 days ago.
