Efficiency evaluation method for cloud resources

The invention provides a cloud resource performance evaluation method. Acquiring operation data of the cloud resources; determining efficiency data based on the operation data of the cloud resources; calculating an efficiency analysis result according to the efficiency data and the QOS rule and weight in the SLA database; if the acquisition and measurement time is consistent with the service period, calculating an efficiency average value in the service period based on the efficiency analysis result, and at the moment, triggering further calculation of the efficiency analysis result between the acquisition and measurement time and the service period, so as to dynamically evaluate the efficiency analysis result, and meanwhile, improving the efficiency of the service period. The efficiency analysis result is related to the efficiency data and the QOS rule and weight in the SLA database, and the user task requirement and the user QOS requirement are synchronously met, so that the user satisfaction is maximized,
