When you enable an Availability Zone for the load balancer, Elastic Load Balancing creates a loadīalancer node in the Availability Zone. ItĪttempts to open a TCP connection to the selected target on the port specified in the After the load balancer receives aĬonnection request, it selects a target from the target group for the default rule. It can handle millions of requests per second.
