AWS AWS_TGW_VPC's architecture diagram

Purpose

Shows how to use AWS with Terraform to accomplish the following tasks:

• Build an AWS TGW
• Build multiple AWS VPC
• Build multiple AWS Subnet
• Build multiple AWS Route table and route
• Attache VPC's to the TGW

Prerequisites

• You must have an AWS account, and have your default credentials and AWS Region configured
• You must have Terraform installed

Cautions

• As an AWS best practice, grant this code least privilege, or only the permissions required to perform a task. For more information, see Grant Least Privilege in the AWS Identity and Access Management User Guide.
• This code has been tested in us-west-1 AWS Regions only. However it should work in any other region.
• Running this code might result in charges to your AWS account.
