摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for computing availability metrics for an integrated service. One of the methods includes generating, for a service installed on a software platform, a plurality of availability logs, each availability log representing an occurrence of the service becoming unavailable. The plurality of availability logs are aggregated according to one or more aggregation criteria. The aggregated availability logs are processed to compute one or more availability metrics for the service, wherein each availability metric quantifies the availability of the service to process requests from the plurality of workloads in the presence of system failures and interruptions. An availability rating for the service is computed from the one or more availability metrics.

摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for allocating tasks to computing nodes using multiple resource allocators. One of the methods includes providing, by each resource allocator of a plurality of resource allocators, a first request to compute a first score to each computing node of a plurality of computing nodes, the first score representing a measure of availability for the computing node to take a particular task. A first score is received from each of the plurality of computing nodes and the nodes are ranked according to the first scores. A second request is provided to a highest-ranked computing node to compute a second score. If the difference between the first score and the second score satisfies a threshold, assigning the task to the highest-ranked computing node if and only if the difference between the first score and the second score satisfies the threshold.
