AWS Hub and Spoke Architecture with AWS Transit Gateway - Terraform Module AWS Transit Gateway is a network hub that you can use to interconnect your VPCs and on-premises networks. With it, you can create hub and spoke architectures to control how your VPCs and on-prem resources communicate between them. In addition, you can centralize different services - like traffic inspection or the connection to VPC endpoints - and therefore avoid extra costs by overprovisioning those services. This Terraform module helps you create the base of your networking infrastructure in AWS, by provisioning a Hub and Spoke Architecture with AWS Transit Gateway. You can indicate which resources you want to centralize - by defining which central VPCs you want to create -, and you get the Transit Gateway, VPCs, a
