    Ensure that the Storage AutoScaling feature is enabled for your Amazon RDS database instances in order to provide dynamic scaling support for the database's storage based on your RDS application needs.
  impact: |
    The RDS instance may run out of storage, leading to potential application downtime or performance degradation due to lack of disk space.
  remediation: |
    Enable storage autoscaling for the RDS instance in the AWS Management Console or via CLI/API to automatically adjust storage capacity as needed.
