Failure as a Service (FaaS): A Cloud Service for Large- Scale, Online Failure Drills

Cloud computing is pervasive, but cloud service outages still take place. One might say that the computing forecast for tomorrow is "cloudy with a chance of failure." One main reason why major outages still occur is that there are many unknown large-scale failure scenarios in which recovery might fail. We propose a new type of cloud service, Failure as a Service (FaaS), which allows cloud services to routinely perform large-scale failure drills in real deployments.
