Research And Implementation Of Reliability Assessment Mechanism For Cloud Environment Based On Cloud Model

When solving the fuzzy phenomena that exist in life,it is necessary to convert qualitative concepts and quantitative values into each other,so it is necessary to establish a qualitative-quantitative conversion model.The cloud model is an uncertainty model for qualitative and quantitative conversion proposed by Academician Li Deyi.When the cloud model inputs a certain element of the domain of discourse,it obtains a set of random numbers with a tendency to be stable,which better preserves the fuzziness and randomness of qualitative concepts.The cloud environment is also a complex system,and its reliability is affected by many factors.If an effective evaluation mechanism can be provided,various cloud service operators will be able to better manage computing resources and enable the system to have a fault-tolerant mechanism.In the process of transforming the operating data of the cloud environment into a qualitative evaluation of reliability,the use of cloud models can better preserve the randomness and fuzziness of qualitative concepts.At the same time,the cloud model is divided into one-dimensional cloud model and multi-dimensional cloud model.The one-dimensional cloud model can analyze the influence of a single influencing factor on the reliability of the cloud environment,and the multi-dimensional cloud model can comprehensively analyze the influence of multiple influencing factors on the reliability of the cloud environment.The reliability of the cloud environment is evaluated through the comprehensive analysis of one-dimensional and multi-dimensional cloud models,which has high credibility.This thesis takes the cloud management platform upgrade project of the company’s data center where the author practiced as the background,and applies the cloud model to the field of cloud environment reliability.The main work is as follows:1)For the first time,the cloud model is applied in the field of cloud environment reliability;2)Use the cloud model to process the data of each resource component in the cloud environment,establish a one-dimensional reliability assessment cloud model for each resource component,and establish a multi-dimensional reliability assessment cloud model for the cloud environment as a whole;3)Proposed a multi-dimensional comprehensive cloud algorithm and a multidimensional similar cloud algorithm,and proved that these two model algorithms are scientific and usable in practical applications;4)According to the different services provided,different weights are set for each resource component during reliability evaluation;5)Experimental analysis is used to verify that the reliability evaluation mechanism based on the cloud model proposed in this thesis can meet the actual needs and has practical value.
