AWS VPC Transit Gateway – Hands On Learning!

Welcome to this Amazing course on AWS VPC Transit Gateway. We will learn by practically implementing AWS VPC Transit Gateway in 3 practical scenarios.

1. Implement Transit Gateway using default route tables.

2. Implement Transit Gateway by sharing it with cross accounts.

3. Implement Transit Gateway by creating multiple custom route tables and controlling the traffic between different VPCs as desired.

4. During the process, we will create VPCs, Subnets, Route Tables, Internet Gateways, and EC2 VMs where we gain knowledge about these features by practically creating them 4 times during the course.
