Wrap Up
Start course

This course explores AWS Transit Gateway - the best way to connect large numbers of VPCs and on-premises networks together. In this course, we are going to cover a lot of important topics that will make your network administrators very happy because they won't have to deal with tens or hundreds of independent connections anymore.

Learning Objectives

  • Learn how to create your own large network topology that uses AWS Transit Gateway to connect multiple VPCs
  • Understand when and why it becomes appropriate to transition away from the standard methods of VPC peering when connecting large numbers of networks

Intended Audience

  • Solutions architects
  • Network engineers
  • Anyone who wants to know more about AWS networking and how to solve some of the larger-scale problems related to it


  • A decent background in computing
  • Basic knowledge of networking within the AWS Cloud
  • Familiarity with network security and on-premises data centers will help to drive some of these points home
  • Experience peering VPCs would also be beneficial, but is not essential

Creating and administering networks within AWS can be complicated. Dealing with all the various ways connections can happen, like VPN peering, Direct connect, VPNs, and standard-issue internet traffic can be a lot to set up and deal with. 

These complications start to expand as your architectures get bigger, and require more and more demands on your time and resources. With the addition of Transit Gateway to your networking, and architecture toolbox - you now have the ability to simplify and route all these disparate connections to one joining service. 

Transit Gateway gives you the power to create complex network topologies all through the use of normal route tables. Transit Gateway also gives you a way to deal with interconnecting traffic between regions. Allowing you to have a web of VPCs in multiple regions all connected together without the ever-increasing amount of VPC peering connections that normally would be required.

Overall, I highly recommend you find some time to play around with this great service, and try to integrate it into your thinking and architecture if you need to build a complex and robust network system - but also don’t be afraid to simply peer the odd VPC here and there. That is a totally fine solution for many problems with AWS.

Well, that brings us to the end of this course. My name is Will Meadows and I'd like to thank you for spending your time here learning about AWS Transit Gateway.  If you have any feedback, positive or negative, please contact us at, your feedback is greatly appreciated, thank you!
