AWS Transit Gateway is now available in 8 additional AWS Regions in the Americas, Europe, and Asia Pacific: Canada (Central), EU (London), EU (Frankfurt), EU (Paris), Asia Pacific (Tokyo), Asia Pacific (Singapore), Asia Pacific (Seoul), and Asia Pacific (Sydney).

AWS Transit Gateway enables customers to connect thousands of Amazon Virtual Private Clouds (VPCs) and their on-premises networks using a single gateway. As you grow the number of workloads in AWS across multiple accounts, you need to scale your networks, control your connectivity policies better, and monitor your network effectively. Today, you can connect pairs of Amazon VPCs using VPC peering. However, managing point-to-point connectivity across 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. This hub and spoke model significantly simplifies management and reduces operational costs because each network only has to connect to the AWS Transit Gateway. With effective routing policies on the Transit Gateway, you have centralized control over how your Amazon VPCs and on-premises networks connect to each other. This connectivity model makes it easy and simple for you to scale and monitor your networks over time.

With this announcement, AWS Transit Gateway is now available in a total of 14 AWS Regions around the world. For more information, see the AWS Transit Gateway product page and documentation.
