Problems solved by technology

The first type mainly studies the energy consumption and time delay of traditional data center processing requests. The problem was raised earlier, and there are a lot of researches; the second type of problem is an extension of the first type of problem, which introduces The new target parameters, the model also mainly refers to the original multi-core scheduling problem, and does not reflect the characteristics of the data center; the third type is also an extension of the first type of problem, mainly by introducing the existing real-time system utility function to measure user performance. Income problem, in this method, one soft job corresponds to multiple utility equations, which can only be applied when the problem scale is small; the fourth method is to solve the problem through theoretical proof, without doing simulation or simulation experiments

Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention should not be limited thereby.

[0029] see figure 2 , figure 2 It is a flow chart of the data center service arrangement method based on user satisfaction in the present invention. As shown in the figure, a data center service arrangement method based on user satisfaction includes the following steps:

[0030] (1) At time t, the number of user requests arriving at the front-end server is N t ;

[0031] (2) Initialize, arrange the data center cost expenses stored in the server terminal in order from small to large;

[0032] (3) Let i=1, k=1;

[0033] (4) Assign service request i to data center D k;

[0034] (5) According to the given user satisfaction, calculate the number of virtual machines that satisfy the service. The specific method is: assuming that the server terminals in the same data cen...

Abstract

The invention discloses a user satisfaction perception-based service placement method for data centers. The method comprises the following steps: first sequencing expenditures of all the data centers at a moment t from low expenditures to high expenditures; then sequentially allocating service requests to each data center under the conditions that the center data has enough virtual machines and that the requirements of the user requests are met, reserving a group of allocation with maximum profit for a computing service provider consistent with the conditions, and placing service in the data center; and after the corresponding service is placed for all the requests, finishing the service placement of the round, and making preparations for the next moment. According to the method, the service is placed in the data centers for the user requests with minimum expenditures by taking the maximization of return of the service providers as a target on the premise of meeting satisfaction of users; and the method is easy in computation, high in operation speed and applied to online large-scale service request scenes.

Description

technical field [0001] The present invention is a data center service layout method based on user satisfaction perception, and particularly relates to a service provider's service layout for geographically distributed data centers, and on the premise of ensuring user satisfaction, through the service layout method to maximize the service provider's income. Background technique [0002] With the rapid development of cloud computing, service providers provide a variety of applications on the cloud to meet the needs of users, such as existing applications such as Google's Docs and AppEngine, Amazon's EC2 and S3, etc. These application services are mostly It is achieved through the arrangement in the data center. Therefore, a large number of service requests will not only increase the demand on the data center, but also increase the power consumption of the data center. According to relevant statistics, Google's data center has about 500,000 servers, and the electricity consum...
