Problems solved by technology

[0004] Since user operations, virtual machine services, and other uncertain factors change all the time, the concurrent access volume of services will not only change steadily over time, but also tend to rise, fall, and cyclically fluctuate. Traditional load models such as exponential smoothing The model can only roughly describe the changing trend of business concurrency, and cannot capture the nonlinear changing characteristics well

Embodiment Construction

[0065] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention.

[0066] In this embodiment, the online air ticket ordering system simulates a PC-side user application, builds the service system on the Dawning server, simulates real business concurrency scenarios by pressurizing the air ticket online ordering system, and collects different business concurrency data as an example , using a method for predicting different types of business concurrency of virtual machines of the present invention to predict the business concurrency. The example topology is as follows figure 1 As shown, client 1 uses LoadRunner software to generate concurrent business access, it can simulate a large number of users clicking on the air ticket ordering system page at the same time...

Abstract

The invention provides a method for predicting concurrent business of different types of virtual machines, and relates to the technical field of cloud computing. A business concurrency prediction method for different types of virtual machines. Firstly, the historical business concurrency of virtual machines is collected and preprocessed, and then the virtual machine business concurrency is judged based on the improved 1nearest neighbor-dynamic time adjustment method 1NN-DTW type; finally, the classification regression tree is used to fit the business concurrency without periodic changes; the Fourier series FS and classification regression tree CART are used to fit the business concurrency with periodic changes; the invention provides different types of virtual machines The business concurrency prediction method based on this method predicts the concurrency of each business of the virtual machine, which can provide a basis for the increase or decrease of the virtual machine in the next step, and at the same time help to accurately estimate the software aging status of the virtual machine, so as to improve the performance of the virtual machine. performance and reliability purposes.

Description

technical field [0001] The invention relates to the technical field of cloud computing, and in particular, to a method for predicting business concurrency for different types of virtual machines. Background technique [0002] Software aging is common in cloud service systems. During the process of virtual machines processing concurrent business requests, operating systems and application software continue to accumulate errors, resulting in the gradual degradation of the performance of working virtual machines, which in turn affects the service quality of cloud service systems. . The highly scalable and dynamic reconfiguration characteristics of the cloud platform provide a technical basis for ensuring the quality of cloud services under different concurrency conditions. However, the existing dynamic adjustment methods for virtual resources still have many defects. [0003] Generally speaking, a variety of services are deployed on virtual machines, and the change trend of th...
