Checks whether backend servers are configured for each Server Load Balancer (SLB) instance and whether the weight of each backend server is not set to 0. If so, the evaluation result is Compliant.
Scenarios
If the weight of a backend server is set to 0, your service may become less responsive or other backend servers may break down due to excessive load.
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 backend servers are configured for each SLB instance and the weight of each backend server is not set to 0, the evaluation result is Compliant.
- If backend servers are configured for an SLB instance but the weight of each backend server is set to 0, the evaluation result is Incompliant. For more information about how to remediate an incompliant configuration, see Incompliance remediation.
