Transit Gateways

A Transit Gateway acts as a hub and helps you connect your VPCs. You can connect VPCs within a region or globally, among different regions. With the help of a transit gateway, you can use a single service for all the attached VPCs.

Note: You can only create up to 2 Transit Gateways within a Region and each Transit Gateway can have up to 10 connections.

Creating a Transit Gateway for your VPC

To create a transit gateway for your VPC, navigate to Transit Gateway and choose your Cloud Account and Region.

Proceed by clicking on the Create Gateway button.

Give your Transit Gateway a Name and select a Resource Group from the list. You can select from two Routing types described below:
