AWS VPC Subnet Architecture Types

- aws networking

This post is part of my note taking while studying for the AWS Certified Advanced Networking - Specialty certification.

There are four subnet types you can have in an AWS VPC:


Private subnets do not have instances with Public IPs a route to an Internet Gateway

VPC Only

This rare subnet architecture provides access to only subnets within the VPC. It’s similar to a private subnet but more restrictive.

VPN Only

This architecture lets a subnet communicate within its VPC and over a VPN to an on-premises data center.


This architecture is used for public services.
