AWS Local Zones concepts

Local Zone — An extension of an AWS Region in geographic proximity to your users, where the Local Zone infrastructure is deployed.

VPC — A virtual private cloud (VPC) is a virtual network that closely resembles a traditional network that you'd operate in your own data center. You create subnets in your VPCs and deploy AWS resources, such as Amazon EC2 instances, in your subnets. A VPC can span Availability Zones, Local Zones, and Wavelength Zones.

Local Zone subnet — A subnet that you create in a Local Zone. You can deploy supported AWS resources in your Local Zone subnets.

Network Border Group — A unique group from which AWS advertises public IP addresses. It consists of Availability Zones, Local Zones, or Wavelength Zones. A pool of public IP addresses can be explicitly allocated for use in a network border group. Once provisioned, IP addresses cannot move between network border groups. For example, the us-west-2-lax-1 network border group consists of two Local Zones in Los Angeles, and the us-east-1-bos-1 network border group consists of a single Local Zone in Boston. You can move an IP address between the two Los Angeles Local Zones, but you cannot move an IP address from a Los Angeles Local Zone to the Boston Local Zone.

When creating a subnet, you will find the network border group for the Local Zones in the Availability Zone drop-down list.

Parent Region — The Region that handles some of the Local Zone and Wavelength Zone control plane operations, such as API calls.

Parent Zone ID — The ID of the zone that handles some of the Local Zone and Wavelength Zone control plane operations, such as API calls
