Checks whether the Server Load Balancer (SLB) instance that you use is of the multi-zone architecture and the resources of multiple zones are added to the server groups used by the listeners of the SLB instance. If so, the evaluation result is Compliant.
Scenarios
Using the multi-zone architecture for SLB instances and adding the resources in multiple zones to server groups can improve the disaster recovery capability of the system and reduce the risk of business interruption.
Risk level
Default risk level: high.
When you apply this rule, you can change the risk level based on your business requirements.
Compliance evaluation logic
If the SLB instance that you use is of the multi-zone architecture and the resources of multiple zones are added to the server groups used by the listeners of the SLB instance, the evaluation result is Compliant.
If the SLB instance that you use is of the single-zone architecture or the resources of multiple zones are not added to the server groups used by the listeners of the SLB instance that you use, the evaluation result is Non-compliant.
