Abstract: Data, attributes, and metrics from unavailable resource hosts may be collected and used for cluster analysis in order to correlate the different hosts and group similar hosts into clusters. The clusters may be ranked based on the collected information and used to provide a simple way to identify shared failure modes among the unavailable hosts. By identifying the hosts of each cluster, shared failures can be corrected for large groups of hosts at the same time, enabling the hosts to return to operational states.

Abstract: A distributed key-value database management system may provide transactions having a high degree of conformance to ACID properties. A data element may be maintained as a versioned list, where each entry may comprise a timestamp and a value indicative of a corresponding version of the data element. The timestamp may be based at least in part on a vended time value. Timestamps may be monotonically increasing and unique across all entries in a distributed system. Conflicting updates to a data element may be detected directly, prior to the completion of involved transactions.
