NET405: Another Day, Another Billion Flows

In this session, we walk through the Amazon VPC network and describe the problems we were solving when we created it, and the features we've been adding as we scale it. We cover how these problems and features are traditionally solved, and why those solutions are not scalable, inexpensive, or secure enough for AWS. Finally, we provide an overview of the solution that we've implemented. We discuss some of the unique mechanisms that we use to ensure customer isolation, get packets into and out of the network, and support new features such as NAT and VPC endpoints.
