Q: What is a transit VPC?

A: A transit VPC is a common strategy for connecting multiple, geographically disperse VPCs and remote networks in order to create a global network transit center. A transit VPC simplifies network management and minimizes the number of connections required to connect multiple VPCs and remote networks.

Q: Why would I implement a transit VPC instead of using multiple connections from my remote networks?

A: A transit VPC can save time and effort, simplify routing, and also reduce costs. There are fewer connections to manage, and because it is implemented virtually on the AWS Cloud, you can forgo the traditional expense of establishing a physical presence in a colocation transit hub or deploying physical network gear.

Q: Can I use a different VPN appliance than the Cisco CSR Amazon Machine Image (AMI) for my transit VPC?

A: This automated transit VPC solution provides a reference implementation with Cisco Cloud Services Router (CSR) 1000V. You can achieve similar architectural patterns using additional AWS Marketplace products.

Q: How much will it cost to run a transit VPC?

A: You are responsible for the cost of the AWS services used while running this reference deployment, as well as for the Cisco CSR licenses, which you can either purchase beforehand or request from the AWS Marketplace. See the implementation guide for detailed information.
