Host machine resource allocation method and device, host machine scheduling method and device

Abstract

Embodiments of the invention provide a host machine resource distribution method and device and a host machine scheduling method and device. The host machine resource distribution method comprises thefollowing steps of: firstly obtaining a first available resource amount of each host machine at the current moment by a server; calculating a second available resource amount of each host machine group and an available resource gross of the host machine groups according to the first available resource amount; calculating an average value of available resource amounts of all the host machine groups according to the quantity of the host machine groups and the available resource gross; respectively calculating a difference value between the second available resource amount of each host machine group and the average value; and finally adjusting the quantity of host machines in the host machine groups, the difference values of which satisfy a preset condition, according to the average value. By applying the scheme provided by the invention, the dynamic and balanced distribution of available resources of the whole host machine group can be ensured, so that the host machine scheduling time consumption is decreased and the host machine scheduling process is accelerated.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a host computer resource allocation method and device, and a host computer scheduling method and device. Background technique [0002] The continuous development of informatization has led to a rapid increase in people's demand for computing and storage resources. In the existing computer field, people need to invest in more hardware equipment and more computer room environment equipment. Therefore, the operation and maintenance costs and manpower The cost has also increased accordingly. In order to save costs, cloud technology is increasingly applied to the computer field. As we all know, cloud service providers are configured with multiple hosts, and all hosts form a host cluster. Cloud service providers configure the resources of multiple hosts in the cloud through cloud technology, and provide Users create corresponding cloud services, for example, create virtual h...

AI Technical Summary

Problems solved by technology

[0004] The number of host machines configured by the cloud service provider is usually thousands, or even tens of thousands. However, in the prior art, the available resources of the host machine cluster are centralized scheduling, the more the number of host machines, traversing all The longer the host time, the longer the host scheduling time
