AWS Transit Gateway is now available in the South America (São Paulo) AWS Region. AWS Transit Gateway enables customers to connect thousands of Amazon Virtual Private Clouds (Amazon VPCs) and their on-premises networks using a single gateway. As you grow the number of workloads across multiple AWS accounts, you need to scale your networks, better control your policies, and effectively monitor your resources.

You can connect pairs of Amazon VPCs using VPC peering. However, managing point-to-point connectivity across a large number of Amazon VPCs without centrally managing connectivity and routing policies, can be operationally costly and cumbersome. This solution can be hard to manage hundreds of Amazon VPCs. 

With AWS Transit Gateway, you only have to create and manage a single connection from a central gateway to each Amazon VPC, on-premises data center, or remote office. AWS Transit Gateway acts as a hub where traffic is routed to all the connected networks, the spokes. The hub and spoke model significantly simplifies management and reduces operational costs because each network only has to connect to the AWS Transit Gateway. With routing policies on the Transit Gateway, you have centralized control over how your Amazon VPCs and on-premises networks connect to each other. This model simplifies how you scale and monitor your networks.

With this announcement, AWS Transit Gateway is now available in a total of 17 AWS Regions around the world. For more information, see the AWS Transit Gateway product page and documentation.
