What triggers this finding
An available RDS instance that is idle (low CPU and fewer than 5 average connections), or one with average CPU below 10% where a smaller instance class is recommended.
Typical fix
Stop the database during off-hours, downsize the instance class, or migrate to Aurora Serverless v2 for variable workloads.
Example savings
25–100% of instance cost depending on whether you stop, downsize, or right-size storage.
