Creating an AWS TGW
To use the AWS TGW (Transit Gateway) feature, you must first create an AWS Transit Gateway.
This step creates an AWS Transit Gateway in a specified region with a specified AWS account. Aviatrix CoPilot also automatically creates the Default_Domain, the Shared_Service_Domain and the Aviatrix_Edge_Domain and the corresponding AWS Transit Gateway route tables.
The three domains are connected. If you attach a VPC to the Default Domain or Shared Service Domain, the VPCs can communicate with each other and can access on-prem environments through the Aviatrix Edge Domain.
