Which AWS networking service provides a central gateway to connect multiple VPCs and on-premises networks?

AWS Transit Gateway is a network transit hub that simplifies network management by connecting thousands of Amazon Virtual Private Clouds (VPCs) and on-premises networks through a central gateway. This eliminates the need for complex peer-to-peer connections, offering a scalable and manageable solution for inter-VPC and hybrid cloud connectivity. Gateway VPC endpoints allow private connections from your VPC to supported AWS services and VPC endpoint services powered by PrivateLink, but they don't connect multiple VPCs or on-premises networks together. AWS Direct Connect establishes a dedicated network connection from your premises to AWS, primarily for hybrid cloud scenarios, but it's not a central routing service for multiple VPCs. AWS PrivateLink provides private connectivity between VPCs and services, but it's for point-to-point service consumption, not a central network hub.
