Interconnecting Virtual Private Clouds with an AWS Transit Gateway

AWS Transit Gateway is a managed and scalable cloud routing resource that can be used to enable network access between different types of networks, including:

• Virtual Private Clouds (VPCs)
• Virtual Private Networks (VPN)
• Direct Connect connections to offices and datacenters
• Other AWS Transit Gateways

Using AWS Transit Gateway enables you to create sophisticated network architectures that are easier to operate and configure than alternative solutions.

Learning to use AWS Transit Gateway will make you more effective at working with complex network scenarios in the public AWS cloud.

In this hands-on lab, you will learn how to create and configure an AWS Transit Gateway to interconnect three existing VPCs.
