AWS Transit Gateway
#127 · Level 4 · Operations and specialized areas · Advanced networking and hybridConcept
Section titled “Concept”AWS Transit Gateway connects many VPCs and office networks through one central hub. Each VPC, VPN or Direct Connect connection is joined to this hub; this is called an attachment. Then the hub’s route table decides which network can talk to which network. As a result, you don’t have to join every VPC to every other VPC separately. With AWS Resource Access Manager, a Transit Gateway can also be shared with other accounts.
Simple example
Section titled “Simple example”An airport hub — instead of direct flights from every city to every city, everyone goes through one hub.
