AWS Gateway Load Balancer
The gateway load balancer (GWLB) uses the gateway load balancer end points to distribute the traffic across the end points. It is a VPC endpoint that provides connectivity in between virtual machines. With GWLB Endpoint as a target, mirrored traffic can be forwarded from any subnet. You can monitor network traffic across multiple VPCs and accounts, with centralized traffic inspection in a single VPC across their entire organization.
