Adding Backend Servers

Scenario

You can add backend servers to a backend server group to process requests from clients.

When you use ELB to route requests, ensure that at least one backend server is running properly and can receive requests routed by the load balancer.

After a backend server is unbound from a load balancer, the backend server does not receive requests forwarded by the load balancer, but the backend server is disassociated from the load balancer. You can add the backend server to the backend server group again when traffic increases or the reliability needs to be enhanced.

Constraints and Limitations

Only servers in the same VPC as the load balancer can be added.
