Internet gateway connection in Local Zones - AWS Local Zones

Internet gateway connection in Local Zones

Internet gateways provide two-way public connectivity to applications running in AWS Regions and/or in Local Zones. For more information, see Internet gateways in the Amazon VPC User Guide.

In the following diagram, end users access a public-facing application in Local Zone 1. Traffic goes directly to the internet gateway in Local Zone 1 without going through the parent AWS Region. Use this type of connectivity for low-latency use-cases where you want your public-facing applications to be closer to end users than an AWS Region can provide.

An AWS Region with a VPC. The VPC contains two Availability Zones and a Local Zone. Each zone has a public subnet and a private subnet. The VPC also has an internet gateway through which traffic passes between an application in the public subnet of the Local Zone and the end user.

For your private applications that require outbound-only connectivity to the internet, use a NAT gateway.
