[RDS.5]

RDS DB instances should be configured with multiple Availability Zones

Description

All RDS DB instances must have high availability enabled. Instances must be configured with multiple availability zones to ensure that stored data is always available. In case of a failure or maintenance on one AZ, the data can be made available from another AZ in a Multi-AZ deployment. This rule is COMPLIANT when an instance has multiple availability zones.
