Cloud Config:slb-all-listener-servers-multi-zone

Last Updated:Jun 23, 2026

Evaluates whether a Server Load Balancer (SLB) instance uses the multi-zone architecture and the server groups of all its listeners contain resources from multiple zones. If both conditions are met, the result is Compliant.

Scenarios

Multi-zone SLB instances with server groups that span multiple zones improve disaster recovery 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

  • The SLB instance uses the multi-zone architecture and the server groups of all its listeners contain resources from multiple zones. The result is Compliant.

  • The SLB instance uses the single-zone architecture, or the server groups of its listeners do not contain resources from multiple zones. The result is Non-compliant.
