About AWS Transit Gateway
AWS Transit Gateway is a fully managed service that connects Amazon Virtual Private Clouds (VPCs) and on-premises networks through a central hub, simplifying network architecture and eliminating complex peering relationships. Acting as a scalable cloud router, it allows each new connection to be made only once. Transit Gateway supports dynamic and static layer 3 routing between VPCs and VPNs, with routes determining the next hop based on the destination IP address. It enables VPN connections between the Transit Gateway and on-premises gateways, supporting Equal Cost Multipath (ECMP) routing to increase bandwidth by load-balancing traffic over multiple paths. AWS Transit Gateway Connect facilitates native integration of Software-Defined Wide Area Network (SD-WAN) appliances into AWS using standard protocols like GRE and BGP, enhancing bandwidth and supporting dynamic routing.
