Method and device of distributing resources

Abstract

An embodiment of the invention discloses a method and a device of distributing resources. The method of distributing the resources comprises the following steps of: receiving a request for distributing the resources for a first business; judging whether the residual resource in a resource pool is smaller than a threshold; if the residual resource in the resource pool is smaller than the threshold, recycling some resources occupied by a second business, wherein after some resources occupied by the second business are recycled, the resources occupied by the second business are not less than reserved resources of the second business, and the reserved resources are least resources divided for the second business in advance; and distributing some recycled resources occupied by the second business to the first business. In the embodiment of the invention, after request for distributing the resources is received, if the residual resource is insufficient, the resources occupied by the business can be adjusted in real time and the resources are distributed according to the business request; through linkage of the business requirement and the resource pool, the service quality is guaranteed and the utilization rate of the resources is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a resource allocation method and device. Background technique [0002] Cloud computing is an increase, use and delivery mode of related services based on the Internet. The deployment of cloud computing usually relies on computer clusters. When the cloud computing infrastructure is adopted, the resources in the cluster need to be managed and scheduled in a unified manner. [0003] In the prior art, when resource allocation is performed, the resource pool is first divided into multiple sub-resource pools according to a predetermined ratio, such as sub-resource pool 1, ... sub-resource pool n, and then the sub-resource pools are allocated to each business, wherein, The resource pool contains all resources, and each sub-resource pool contains a certain amount of resources, which may be virtualized CPUs, memory, and so on. There is a one-to-one relationship between a busine...

Problems solved by technology

[0004] However, the resource demand of business is uncertain, which is specifically related to the business volume in the current time period. Assume that sub-resource pool a and sub-resource pool b are allocated to service A and service B respectively. If service A’s The business volume has increased sharply, while the business volume of business B has decreased sharply, which will inevitably cause the business of business A to fail to obtain resources normally, while the resources of business B are excessive

Therefore, the resource allocation method in the prior art cannot make full use of the resources of the resource pool
