Elastic load balancing requires two basic elements to function properly: a load balancer and instances registered with that load balancer. The following examples show how to modify the basic elements of an elastic load balancer configuration.
De-register instances from the Load Balancer
The load balancer monitors the health of registered instances, and balances incoming traffic across the healthy instances.To deregister an instance from the load balancer: Enter the following command:
eulb-deregister-instances-from-lb --instances INSTANCE1,INSTANCE2,... MyLoadBalancer
Enter the following command to verify that the instances are deregistered from the load balancer: eulb-describe-instance-health MyLoadBalancer This command will return output similar to the following:
INSTANCE i-6FAD3F7B InService
Delete Load Balancer Listeners
To delete a load balancer listener:
Enter the following command:
eulb-delete-lb-listeners --lb-ports PORT1,PORT2,... MyLoadBalancer
Delete Load Balancer
To delete a load balancer:
Enter the following command:
eulb-delete-lb MyLoadBalancer
You’ve now deleted the elastic load balancer.
