AWS networking hub that connects multiple networks together through a central point. Like a major highway interchange where all roads meet - instead of building direct connections between every city, you build one central hub.
A large company uses Transit Gateway to connect 50 different VPCs across multiple regions, simplifying their network architecture from hundreds of connections to just 50.
AWS Transit Gateway serves as a central hub for connecting VPCs, similar to Azure Virtual WAN, GCP's Cloud Interconnect, and OCI's Dynamic Routing Gateway, which provide similar functionalities in their respective cloud environments.
