Setup AWS Transit Gateway

Wed, 12 Dec 2018 15:00:07 +0000

Amazon announced a new service at re:Invent 2018 in Las Vegas, called the AWS Transit Gateway. The Transit Gateway allows you to connect multiple VPCs together as well as VPN tunnels to on-premises networks through a single gateway device. As a consultant, I talk with customers often, about how they will plan to connect their data center with the AWS cloud, and how to interconnect all of those VPCs. In the past a solution like Aviatrix or a Cisco CSR transit gateway was used which leveraged some EC2 instances that lived within a VPC. You’d then connect spoke VPCs together via the use of VPN tunnels. With this new solution, there is a native service from AWS that allows you to do this without the need for VPN tunnels between spoke VPCs and you can use the AWS CLI/CloudFormation or console to deploy everything you need. This post takes you through an example of the setup of the AWS Transit Gateway in my own lab environment.
