Method and device for realizing data center resource load balance in proportion to comprehensive allocation capability

Abstract

The invention relates to a method and a device for realizing data center resource load balance. The method of the technical scheme comprises the following steps of: acquiring the current utilization rates of attributes of each physical machine in a scheduling domain, and determining the physical machine for a currently allocated task according to the principle of fair distribution in proportion to the allocation capability of a server, an actual allocated task weight value and an expected task weight value, wherein the attributes comprise a central processing unit (CPU) load, a memory load and a network load; determining a mean load value of the attributes of the scheduling domain according to the current utilization rates, and calculating a difference between the actual allocated task weight value and expected task weight value of the physical machine according to the mean load value and predicted load values of the attributes of the physical machine; and selecting the physical machine of which the difference between the actual allocated task weight value and the expected task weight value is the smallest for the currently allocated task. The device provided by the invention comprises a selection control module, a calculation processing module and an allocation execution module. By the technical scheme provided by the invention, the problem of physical server load unbalance caused by inconsistency between user need provisions and physical server provisions can be solved.

Description

1. Technical field [0001] The present invention relates to the technical field of computer applications, and more specifically, to a method and device for realizing data center resource load balancing. 2. Background technology [0002] As a large server cluster, the cloud computing data center has a large number of physical servers with different specifications and configurations. Through virtualization technology, each physical server can virtualize multiple virtual machines to allocate and schedule resources for users. Usually cloud computing data center scheduling system such as figure 1 As shown: the user initiates a request through the Internet; the super dispatch center submits the request to the appropriate data center according to the identity characteristics of the user and the service characteristics of the request, and then submits the request to a dispatch domain by the management program of the data center. Execute a certain scheduling algorithm to request allo...
