Full-disclosure: I'm an engineer at Amazon Web Services. "Mr. Hamilton later said privately that Amazon had developed original statistical methods to limit damage from catastrophic failures." I don't think it's what James is referring to (as it's just the tip of the iceberg), but at Re:Invent we also released Infima - a library for service-level fault isolation and fault tolerance using Route 53 for endpoint discovery; https://github.com/awslabs/route53-infima https://github.com/awslabs/route53-infima The techniques in Infima give some insight into how we think about multi-tenancy and availability, as well as provide a framework for building other services on top of EC2, Route 53 and so on.
