Amazon Local Zones concepts

These are the essential concepts in Amazon Local Zones:

  • Local Zone — An extension of an Amazon 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 Amazon resources, such as Amazon EC2 instances, in your subnets.

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

  • Group Long Name — The Local Zone group name.

  • Network Border Group — A unique group from which Amazon advertises public IP addresses. 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.

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

Considerations

  • Local Zone subnets follow the same routing rules as Availability Zone subnets, including the use of route tables, security groups, and network ACLs.

  • You cannot create VPC endpoints inside Local Zone subnets.

  • The Amazon Site-to-Site VPN is not available in Local Zones. Use a software-based VPN to establish a site-to-site VPN connection into a Local Zone.
