Transit Gateway Hub-and-Spoke - Platform Engineering Hands-On Lab Icon

Lab Overview

Build a hub-and-spoke network on AWS using Transit Gateway. You will create three VPCs with non-overlapping CIDRs, attach them to a shared Transit Gateway, configure route tables for transitive routing, and validate cross-VPC connectivity by pinging EC2 instances across all three VPCs.

You'll learn to:

  • Create multiple VPCs with non-overlapping CIDR blocks
  • Provision and configure an AWS Transit Gateway
  • Create Transit Gateway attachments for each VPC
  • Set up route tables for transitive routing through the TGW
  • Launch EC2 instances and test cross-VPC ICMP connectivity
