Checks whether an ApsaraDB RDS instance is deployed across multiple zones.
Scenario
To ensure strong disaster recovery capacities and prevent business system interruption, you can deploy ApsaraDB RDS instances across multiple zones.
Note Zones are isolated locations in regions. Each zone has its own independent power supply and network.
Risk level
Default risk level: low.
You can change the risk level as required when you apply this rule.
Compliance evaluation logic
- If the ApsaraDB RDS instance is deployed across multiple zones, the configuration is considered compliant.
- If the ApsaraDB RDS instance is deployed in only one zone, the configuration is considered non-compliant. For more information about how to correct the non-compliant configuration, see Non-compliance remediation.
