Transit VPC

A transit Virtual Private Cloud (VPC) connects multiple VPCs and remote networks in order to create a global network transit center.

To increase network agility, organizations need to automate data transfer processes and replace legacy routing solutions that add latency and limit bandwidth and availability. Amazon Virtual Private Cloud (VPC) allows businesses to provision a logically isolated section of the Amazon Web Services Cloud where they can launch Amazon Web Services resources in a virtual network that they define.

Transit VPCs help organizations transfer data from one Amazon VPC to another, simplifying operations and eliminating the latency issues by peering between resources. A Transit VPC can also add capability and flexibility to Amazon Virtual Private Clouds.
