Create and manage Transit Gateway

A Transit Gateway is a centralized network transit hub that enables you to connect multiple VPCs (Virtual Private Clouds) and on-premises networks easily and flexibly. It supports multi-availability zone functionality, a key technology for improving application fault tolerance and availability, so you can prepare for disaster recovery and improve overall system availability.
