Does RDS Support Cross-AZ High Availability?

Yes, RDS supports cross-AZ high availability. By default, primary/standby RDS DB instances are created in different AZs. When you create primary/standby DB instances and select different primary and standby AZs, the system will automatically deploy the primary and standby DB instances in different AZs.
