Whatโs changing
Starting today, weโre changing the way that your functions connect to your VPCs. AWS Hyperplane, the Network Function Virtualization platform used for Network Load Balancer and NAT Gateway, has supported inter-VPC connectivity for offerings like AWS PrivateLink, and we are now leveraging Hyperplane to provide NAT capabilities from the Lambda VPC to customer VPCs.
The Hyperplane ENI is a managed network resource that the Lambda service controls, allowing multiple execution environments to securely access resources inside of VPCs in your account. Instead of the previous solution of mapping network interfaces in your VPC directly to Lambda execution environments, network interfaces in your VPC are mapped to the Hyperplane ENI and the functions connect using it.
