Cloud Config:rds-high-availability-category

Last Updated:Nov 10, 2025

Checks whether the edition of an ApsaraDB RDS instance is High-availability.

Scenario

If a primary instance fails in an ApsaraDB RDS instance of High-availability Edition, applications automatically switch to a standby instance. This improves system stability and prevents business system interruption.

Risk level

Default risk level: high.

You can change the risk level as required when you apply this rule.

Compliance evaluation logic

  • If the edition of the ApsaraDB RDS instance is High-availability, the configuration is considered compliant.
  • If the edition of the ApsaraDB RDS instance is Basic, the configuration is considered non-compliant. For more information about how to correct the non-compliant configuration, see Non-compliance remediation.
