Implementing Automatic Safe Hands-off Deployment in AWS

One of my clients asked me to implement the solution Clare Liguori of AWS described in Automating safe, hands-off deployments. It’s a very interesting and detailed document describing how Amazon deploys code to production with no human interaction. It describes safe continuous delivery in cloud scale that minimizes developers interaction and failure points.
