ELBv1 load balancer cross zone load balancing should be enabled¶
Description¶
Having Availability Zone with the Cross-Zone Load Balancing feature enabled for the VPC reduces the risk of failure at a single location as the AWS Elastic Load Balancers distribute the traffic to the other locations.
Remediation Steps¶
AWS Console¶
Navigate to EC2.
On the navigation pane, under LOAD BALANCING, choose Load Balancers.
Select the load balancer associated with your VPC.
On the Description tab, choose Change cross-zone load balancing setting.
On the Configure Cross-Zone Load Balancing page, select Enable.
Choose Save.
AWS CLI¶
aws elb modify-load-balancer-attributes --load-balancer-name <name> --load-balancer-attributes "{\"CrossZoneLoadBalancing\":{\"Enabled\":true}}"
