System and method for predicting non-steady application user concurrency in cloud environment

Abstract

The invention provides a system and method for predicting the non-steady application user concurrency in a cloud environment, and relates to the technical field of service performance optimization in the cloud environment. The system comprises a historical data obtaining module, a non-steady service judgment module and an application user concurrency prediction module; historical data is analyzed; identification of service properties is carried out; therefore, the fact that a concurrency sequence has the tendency or the periodicity is judged; and concurrency prediction is carried out respectively for the two properties. According to the system and the method provided by the invention, for the characteristics of the tendency and periodic application user concurrency of non-steady services in the cloud environment, a prediction model is constructed by utilizing different prediction methods; the concurrency containing two properties is predicted; characteristics of a tendency and periodic concurrency sequence can be automatically identified; furthermore, the periodicity of the sequence can be automatically calculated; manual intervention is unnecessary; the prediction process can be automatically completed; and simultaneously, the non-steady service concurrency prediction accuracy can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of service performance optimization in a cloud environment, in particular to a system and method for predicting the concurrent amount of non-stationary application users in a cloud environment. Background technique [0002] With the complexity of the cloud application service system and the openness, dynamics and uncontrollability of its operating environment, the concurrency carried by the cloud application service system at different points in time has significant differences, and often presents along a certain regular non-stationary trend. Application user concurrency refers to the number of user requests per unit time of the application. The cloud application service system achieves the purpose of ensuring the stability and effectiveness of the cloud service system by monitoring the concurrent application users, analyzing and predicting the concurrent application users in history, and implementing appro...

However, the existing researches are all focused on the forecasting algorithm, trying to establish a general forecasting algorithm to suit various applications, which will inevitably lead to the improvement of the generality of the algorithm and the decrease of the accuracy.

However, the amount of concurrency itself does not have a specific nonlinear mode. Different applications, due to differences in nature, require corresponding and suitable prediction methods to predict the amount of concurrency
