Connection Draining
Allowing in-flight requests on an instance to complete before it is removed from service, rather than terminating them at cutover.
conceptCross-Zone Load Balancing
Whether a load balancer node distributes traffic to targets in all zones or only its own — a setting that affects both balance and data transfer cost.
