If the compute node of the PolarDB cluster uses dedicated specifications, the evaluation result is Compliant.
Scenarios
Dedicated nodes enjoy dedicated CPU and memory resources. The performance of a dedicated node is guaranteed and is not affected by the other clusters that are deployed on the same physical host.
Risk level
Default risk level: low.
When you apply this rule, you can change the risk level based on your business requirements.
Compliance evaluation logic
- If the compute node of the PolarDB cluster uses dedicated specifications, the evaluation result is Compliant.
- If the compute node of the PolarDB cluster does not use dedicated specifications, the evaluation result is Incompliant. For more information about how to remediate an incompliant configuration, see the "Incompliance remediation" section of this topic.
