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 implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0066] In this embodiment, the online air ticket ordering system is used to simulate the application of PC end users, and the service system is built on the Sugon server, and the real business concurrency scene is simulated by pressurizing the air ticket online ordering system, and different business concurrency data are collected as an example , using a business concurrency prediction method for different types of virtual machines of the present invention to predict the business concurrency. Instance topology such as figure 1 As shown, client 1 uses LoadRunner software to generate concurrent business access, which can simulate a large number of users clicking on the plan...

Abstract

The invention provides a method for predicting different types of business concurrency of a virtual machine, and relates to the technical field of cloud computing. A method for predicting different types of business concurrency of a virtual machine comprises the following steps: firstly, acquiring historical business concurrency of the virtual machine, preprocessing the historical business concurrency, and then judging the type of the virtual machine service concurrency based on improved 1 nearest neighbor-dynamic time adjustment method 1NN-DTW; and finally fitting the business concurrency without periodical change by adopting a classification regression tree. Fitting business concurrency with periodic change by adopting Fourier series FS and a classification regression tree CART; according to the method for predicting the concurrency of different types of services of the virtual machine, the concurrency of each service of the virtual machine is predicted, a basis can be provided for the next step of increase or decrease of the virtual machine, and meanwhile, the software aging condition of the virtual machine can be accurately estimated, so that the purpose of improving the performance and reliability of the working virtual machine is achieved.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method for predicting concurrent business of different types of virtual machines. Background technique [0002] Software aging generally exists 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 a gradual decline in the performance of working virtual machines, which in turn affects the service quality of cloud service systems. . The high scalability and dynamic reconfiguration characteristics of the cloud platform provide a technical basis for ensuring the quality of cloud services under different concurrency conditions. However, there are still many defects in the existing dynamic adjustment methods of virtual resources. [0003] Generally speaking, various services are deployed on virtual machines, and the changing trends of th...
