AWS Transit Gateway and Service-linked Role

Overview

By employing a “hub-and-spoke”architecture, AWS Transit Gateway centralizes connectivity between large IT deployments both on-premises and in the AWS Cloud. With additional features such as AWS Transit Gateway Inter-Region Peering and AWS Transit Gateway Network Manager, organizations can build out simplified global enterprise network architectures.
