The private cloud platform of China Mobile enterprise has five technical characteristics, namely, the integration of cloudnetwork side, super-large scale, cloud native architecture, independent control, and full stack base. In the current operation and man-agement of cloud platform, to ensure the effective use of company resources, an effective means is to analyze the user value of theplatform. For a long time, there has been a lack of scientific analysis means in this aspect, and the discriminant method based on per-sonal experience is often adopted, which lacks reliability. This paper puts the values of private cloud users into five dimensionswhich are resource utilization, resources rationality, user economy value, science and technology innovation value, politic and man-agement. It constructs the feature engineering and model algorithm based on user basic data, and establishes the evaluation methodfrom two aspects of expert evaluation model and objective scoring model, outputting user value scores and selecting high value us-ers
