    Ensure that your Amazon RDS instances are using the Multi-AZ deployment configuration for high availability and automatic failover support, fully managed by AWS.
  impact: |
    The RDS instance lacks high availability and failover support, increasing the risk of downtime during instance failures or maintenance events.
