AWS NAT Gateway now supports regional availability

Amazon Web Services (AWS) announces regional availability mode for NAT Gateways. With this launch, you can create a single NAT Gateway that automatically expands and contracts across availability zones (AZs) in your Virtual Private Cloud (VPC) based on your workload presence, to maintain high availability while offering simplified setup and management.

A NAT Gateway enables instances in a private subnet to connect to services outside your VPC using the NAT Gateway's IP address. With this launch, you can create a NAT Gateway and set its availability to regional. You do not need a public subnet to host a regional NAT Gateway. You also do not have to create and delete NAT Gateways, and edit your route tables every time your workloads expand to new availability zones. You simply create a NAT Gateway with regional mode, choose your VPC, and it automatically expands and contracts across all availability zones based on your workload's presence, maintaining high availability. You can use this feature with Amazon provided IP addresses or bring your own IP addresses.

This feature is available in all commercial AWS Regions, except for AWS GovCloud (US) Regions and China Regions**.** To learn more about VPC NAT Gateway and this feature, please visit our documentation
