Problems solved by technology

[0005] However, random selection of hosts to run virtual machines means that a reasonable number of virtual machines is not configured according to the resources of each host, resulting in a large difference in the load of each host, so that load balancing must be achieved through migration of virtual machines, and the migration of virtual machines is wasteful. The resources of the cloud data center are reduced, and the user experience is reduced

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions of the exemplary embodiments provided by the present invention with reference to the accompanying drawings in the embodiments of the present invention.

[0021] refer to figure 1 As shown, a cloud computing system according to an embodiment of the present invention includes a cloud management platform 1 and a resource pool 2 . The resource pool 2 mainly includes a virtual computing resource pool, a virtual network resource pool and a virtual storage resource pool. Among them, the virtual computing resource pool is formed by one or more physical hosts (21-2n) through virtualization technology, including CPU, memory and other resources; the virtual network resource pool is formed by various network devices such as routers, switches, load balancers, etc. Formed by virtualization technology, it includes resources such as network bandwidth; the storage resource pool is formed by various storage devic...

Abstract

The invention provides a resource scheduling method and device in a cloud computing system. By judging in advance whether load balance assessment values of at least two hosts in a migration domain surpass a preset threshold value, that is, whether load oscillation is caused between the hosts, if the host, the load of which is minimum, bears operation of a virtual machine, and when load oscillation is not caused, the host is allowed to bear operation of the virtual machine, that is, the host, the load of which is smaller, operates one or a batch of virtual machines, load difference with the host, the load of which is larger, is reduced, and the load of each host in the migration domain is allowed to be same or similar.

Description

technical field [0001] The present invention relates to the field of IT (Internet Technology, Internet technology), in particular to a method and device for resource scheduling in a cloud computing system. Background technique [0002] Virtualization technology is one of the key technologies in the field of cloud computing. It can virtualize physical resources into multiple virtual machines (Virtual Machine, VM). Physical resources are provided to each virtual machine in the form of a virtual resource pool by the virtualization platform. The virtual machine share physical resources. [0003] Compared with traditional data centers, cloud data centers that use virtualization technology to provide computing, storage, and network resources are highly concentrated and uniformly scheduled and managed, which greatly saves operating and maintenance costs. The cloud data center allocates virtual machine resources according to requirements and policies, and based on the DRS (Distribu...
