Over-provisioned RDS instance

An RDS database running on a larger instance class than its workload requires.

Last updated July 3, 2026

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.
