An AWS Virtual Private Cloud (VPC) Gateway Endpoint is a VPC component that allows you to privately connect your VPC to supported AWS services and VPC endpoint services powered by PrivateLink, without requiring an Internet Gateway, NAT device, VPN connection, or AWS Direct Connect connection.
A VPC Gateway Endpoint is a horizontally scaleable, highly available, low-latency connection to a supported service. It allows traffic to flow between instances in your VPC and the service without traversing the Internet or an AWS Direct Connect link.
There are two types of VPC Gateway Endpoints:
Interface VPC Endpoints: Interface VPC endpoints are horizontally scaleable network interfaces that are connected to your subnet. They allow you to connect to supported AWS services, such as S3 and DynamoDB, as well as VPC endpoint services powered by PrivateLink.
Gateway VPC Endpoints: Gateway VPC endpoints are horizontally scaleable, highly available, low-latency connections to supported AWS services, such as S3 and DynamoDB, that use a gateway.
