| Plugin Title | RDS Multiple AZ |
| Cloud | AWS |
| Category | RDS |
| Description | Ensures that RDS instances are created to be cross-AZ for high availability. |
| More Info | Creating RDS instances in a single AZ creates a single point of failure for all systems relying on that database. All RDS instances should be created in multiple AZs to ensure proper failover. |
