An Internet Gateway is a logical connection between an AWS VPC and the Internet. It allows for internet traffic to actually enter into a VPC. We look at how to set it up.

Introduction

In the previous post on AWS VPC Basics, we learned about VPC basics and we also set up a VPC with public and private subnets.

In this post, we will learn about another powerful component from AWS, the gift of the internet, The Internet Gateway. We will also learn how routing works within VPC, how to set up routes to the internet gateway and our public subnet. This setup is very common for most of the applications on AWS.

An internet gateway is a service that allows for internet traffic to actually enter into a VPC. Otherwise, a VPC is completely segmented off and then the only way to get to it is potentially through a VPN connection rather than through an internet connection.
