AWS Transit Gateway now supports Inter-Region Peering

Posted on: Dec 3, 2019

AWS Transit Gateway now supports the ability to establish peering connections between Transit Gateways in different AWS Regions. Transit Gateway is a service that enables customers to connect thousands of Amazon Virtual Private Clouds (Amazon VPCs) and their on-premises networks using a single gateway. With AWS Transit Gateway, customers only have to create and manage a single connection from a central regional gateway to each Amazon VPC, on premises data center, or remote office across their networks.

The ability to peer Transit Gateways between different AWS Regions enables customers to extend this connectivity and build global networks spanning multiple AWS Regions. Traffic using inter-region Transit Gateway peering always stays on the AWS global network and never traverses the public internet, thereby reducing threat vectors, such as common exploits and DDoS attacks. Inter-region Transit Gateway peering encrypts inter-region traffic with no single point of failure.

Inter-region Transit Gateway peering is available in US East (N. Virginia), US East (Ohio), US West (Oregon), EU (Ireland), and EU (Frankfurt) AWS Regions. Support for other AWS Regions is coming soon. For more information, see the AWS Transit Gateway product page and documentation.
