AWS - How To Access Resources Privately Using Transit Gateway | Part-1 | Demo
A transit gateway is a type of network transit hub used in cloud computing environments to interconnect virtual private clouds (VPCs) and on-premises networks. It provides a centralized control plane for routing traffic between multiple VPCs, on-premises data centers, and remote networks.

A transit gateway acts as a hub for network traffic, enabling organizations to consolidate their network connectivity and simplify network management. With a transit gateway, VPCs can be connected to each other and to on-premises networks using a single, centrally managed gateway. This eliminates the need for each VPC to have its own VPN connection to on-premises resources, reducing the complexity and cost of managing multiple connections.

Transit gateway also offers advanced routing capabilities, including route filtering, path selection, and network address translation (NAT). These features provide greater control over how traffic flows between VPCs and on-premises networks.

In summary, a transit gateway is a highly scalable, fully managed service that simplifies network connectivity and provides advanced routing capabilities for multi-VPC and multi-account architectures in cloud computing environments.
