Ensure ELB cross-zone load balancing is enabled
Cross-zone load balancing distributes traffic evenly across all registered targets in all enabled Availability Zones.
Security Impact
Without cross-zone balancing, traffic may be unevenly distributed, overloading some targets.
How to Remediate
Enable cross-zone load balancing in load balancer attributes. This is default for ALB but must be enabled for NLB.
