Checks whether each Application Load Balancer (ALB) server group includes at least two servers. If so, the evaluation result is Compliant.
Scenarios
This rule applies when you need to add multiple servers to an ALB server group. An ALB server group that contains multiple servers provides high performance and availability. This ensures business stability.
Risk level
Default risk level: high.
When you configure this rule, you can change the risk level based on your business requirements.
Compliance evaluation logic
- If each ALB server group includes at least two servers, the evaluation result is Compliant.
- If an ALB server group includes no server or only one server, the evaluation result is Incompliant. For more information about how to remediate an incompliant configuration, see Incompliance remediation.
