FATE and DESTINI: A Framework for Cloud Recovery Testing

As the cloud era begins and failures become commonplace, the fate and destiny of availability, reliability and performance are in the hands of failure recovery. Unfortunately, recovery problems still take place, causing downtimes, data loss, and many other problems. The authors propose a new testing framework for cloud recovery: FATE (Failure Testing Service) and DESTINI (Declarative Testing Specifications). With FATE, recovery is systematically tested in the face of multiple failures. With DESTINI, correct recovery is specified clearly, concisely, and precisely. They have deployed the framework in three cloud systems (HDFS, ZooKeeper, and Cassandra), explored over 40,000 failure scenarios, wrote 74 specifications, found 16 new bugs, and reproduced 51 old bugs.
