Network Load Balancer has now added support for Cross Zone Laod Balancing

Network Load Balancer distributes request indifferent of the Availability Zone with the support of the cross-zone load balancing. This new feature will enable Network Load Balancer to link incoming request to the application that is deployed on multiple Availability Zones. Network Load Balancer depends on the Domain Name System to distribute request from clients to the Network Load Balancer nodes that deploy at multiple availability zones. Earlier the network load balancer routed the request to a target located in the same availability zone. Some targets can receive a disproportionally with a high number of inbound request where the clients can cache the DNS information of the zonal network load balancer.
