As your cloud infrastructure expands globally you need to find out a way to connect your resources which are in different VPCs. A Transit Gateway is a network hub that you can use to interconnect your virtual private clouds (VPCs) and on-premises networks.

It is a regional service. It gives you simplified connectivity to the multiple VPC as compared to a complex VPC peering connection. Traffic between VPC and Transit Gateway remains on the AWS global private network and is not exposed to the public internet. Transit Gateways in different regions can peer with each other to enable VPC communications across regions. Transit Gateway inter-Region peering encrypts all traffic, with no single point of failure or bandwidth bottleneck which helps you to get improved security.
