AWS Direct Connect

AWS Direct Connect makes it easy to establish a dedicated network connection from your premises to your Amazon VPC or among Amazon VPCs. This option can potentially reduce network costs, increase bandwidth throughput, and provide a more consistent network experience than the other VPC-to-VPC connectivity options.

You can divide a physical AWS Direct Connect connection into multiple logical connections, one for each VPC. You can then use these logical connections for routing traffic between VPCs, as shown in the following figure. In addition to intra-region routing, you can connect AWS Direct Connect locations in other regions using your existing WAN providers and leverage AWS Direct Connect to route traffic between regions over your WAN backbone network.

We recommend this approach if you’re already an AWS Direct Connect customer or would like to take advantage of AWS Direct Connect’s reduced network costs, increased bandwidth throughput, and more consistent network experience. AWS Direct Connect can provide very efficient routing since traffic can take advantage of 1 GB or 10 GB fiber connections physically attached to the AWS network in each region. Additionally, this service gives you the most flexibility for controlling and managing routing on your local and remote networks, as well as the potential ability to reuse AWS Direct Connect connections.
