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 VPC's as desired.

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