Resource distribution method and system

Abstract

The invention discloses a resource distribution method. The method comprises the steps that the preset resource amount is satisfied in a preferential manner for resources distributed to a virtual system when a resource system of a cloud platform distributes resources to the virtual system in a weight resource distribution way and when the virtual system is configured with the preset resource amount. The invention also discloses a resource distribution system for realizing the above method. The resource system of a cloud platform distributes resources to the virtual system in a weight resource distribution way, and a user can set the reserved resource amount and the maximum resource amount for needs of resources on the basis of loaded applications. When the virtual system is powered to start or resources of the resource system change in a dynamic manner and dynamic resource adjusting for the virtual system is needed, all resources needed by the virtual system are guaranteed and services born by the virtual system can run normally. Based on a reasonable resource distribution mode, resource demands of as many users as possible are satisfied and thus the service quality of the cloud platform is improved.

Description

technical field [0001] The present invention relates to resource allocation technology, in particular to a resource allocation method and system. Background technique [0002] Virtualization technology divides physical resources into multiple logical partitions on a physical server through the virtualization software Hypervisor, and each partition is isolated from each other and becomes an independent virtual machine. Virtual machines share the resources of the same physical server, and there is no difference between virtual machines and physical servers for operating systems and applications. [0003] In the traditional data center and cloud computing environment, the resource application of the virtual machine can adopt the resource allocation method of setting the reserved resource amount and the maximum resource amount, that is, setting the minimum threshold and the maximum threshold of the physical resources occupied by the virtual machine. Also known as the absolute r...

Problems solved by technology

[0015] For a cloud computing environment, its overall resource volume may change dynamically with time, environment, and various external conditions. For example, some servers will be shut down at night to save energy and reduce emissions, and the dynamic expansion of the system will increase server resources. drop in volume

If the dynamic change of the overall resource amount of the cloud platform resource system reaches a certain preset condition, the resource system needs to dynamically adjust the resources of the hosted virtual system. For the weighted resource allocation method, if the reserved resource amount of the virtual system is not set and the maximum amount of resources will cause the resources allocated according to the weighted resource allocation method may not be able to meet the normal operation of the virtual system, resulting in a decline in the quality of service provided; in severe cases, the virtual system will be abnormal and unable to provide external services; or in the resource system In the case of capacity expansion, the hosted virtual system takes up too many resources, resulting in resource redundancy and waste
