A company runs workloads in multiple VPCs in the us-east-1 Region.

This solution provides a scalable and flexible architecture that accommodates future growth while ensuring connectivity between regions and locations.

New Direct Connect Connection in London: Establishing a Direct Connect connection for the London office provides a high-performance, private, and reliable connection between the office and AWS.

Use the Existing Direct Connect Gateway: By attaching the new Direct Connect connection to the existing Direct Connect gateway, the solution leverages the existing infrastructure, reducing operational complexity.

Transit Gateway in eu-west-2: The transit gateway in eu-west-2 enables centralized routing and connectivity management for multiple VPCs in that Region.

Transit Gateway Peering: Peering the transit gateways inus-east-1andeu-west-2ensures seamless private connectivity between the regions, allowing users in the US and London to access workloads in both regions.

This design ensures low operational effort because it avoids creating and managing multiple individual VPN connections. It also supports future growth by allowing additional VPCs, regions, or office locations to connect with minimal configuration changes.
