specific Embodiment approach

[0158] Specific embodiments are as follows.

[0159] The central control module 200 is configured to collect the total amount of resources of each virtual machine 100 and feed back the total amount of resources of each virtual machine 100 to the scheduler module 300 .

[0160] The scheduler module 300 is configured to collect the resource utilization rate of each virtual machine 100 and the number of service request connections.

[0161] The scheduler module 300 is also configured to update the weight of the virtual machine 100 according to the current weight of the virtual machine, the total amount of resources, the resource utilization rate and the number of service request connections.

[0162] The scheduler module 300 judges whether the virtual machine is overloaded according to the total amount of resources of the virtual machine 100, resource utilization and the number of service request connections, if overloaded, the weight of the virtual machine 100 is recorded as a p...

Abstract

The invention relates to a method and a system thereof for dispatching application requests in a virtual calculation platform.The method comprises the following steps: (1) collecting the total resource quantity, the resource utilization rate and the connection number of the service requests of each virtual machine; (2) according to the current weight value, the total resource quantity, the resource utilization rate and the connection number of the service requests of the virtual machines, updating the weight value of the virtual machines; and (3) dispatching the service requests by adopting apolling dispatching method based on the weight value. The invention can realize the matching of resources and loads in the system of the virtual machines and enhance the utilization efficiency of theentire virtual calculation platform.

Description

technical field [0001] The invention relates to the field of virtual clusters, in particular to a method and system for scheduling application requests in a virtualized computing platform. Background technique [0002] In the prior art, a method for improving resource utilization is to use virtualization technology to integrate a large number of network services into a shared framework, and allocate overall resources among virtual machines. [0003] One of the methods for realizing the virtualization technology in the prior art is the Web cluster method. A Web cluster refers to a network service site in which two or more servers are united through the network to jointly process user requests. Although a large-scale cluster has a large number of server nodes, it uses a host to provide a unique access interface for all users. In order to control all requests to reach the site and shield the distributed server structure in the background, the Web cluster provides a network sw...
