  Transit Gateway : A transit gateway is an AWS service that allows you to create a centralized network hub, making it easier to connect and manage multiple VPCs. Attaching VPCs to the transit gateway : By attaching the VPCs to the transit gateway, you can extend your existing Site-to-Site VPN connections across the different regions or accounts. Creating additional Site-to-Site VPN connections : Adding more Site-to-Site VPN connections that terminate on the transit gateway will increase the available bandwidth and improve overall network throughput. Equal-cost multi-path (ECMP) routing : By configuring ECMP routing, you can direct traffic across multiple VPN connections, increasing the utilization of each connection and improving the overall performance.
