What triggers this finding
A running EC2 instance on a large size (xlarge and above) with average CPU between 0% and 20% over the last 30 days, where a smaller instance type is available.
Typical fix
Downsize to the recommended instance type. Paid plans include a CLI script to modify the instance type — review warnings and schedule a maintenance window first.
Example savings
The difference between current and recommended instance pricing — often 25–50% of instance cost.
