Problems solved by technology

[0004] However, the above monitoring-based elastically scalable virtual machine cluster technology has the following problems: Since the monitoring has a certain delay, it is necessary to wait until the monitoring data is collected and the monitoring data reaches the threshold before adding new virtual machines or releasing virtual machines in the cluster. machine; and it takes a certain amount of time to create a newly created virtual machine, which leads to a relatively long lag in the entire scaling process
In addition, homogeneous virtual machines have the same configuration level, which is not conducive to maximizing the resource utilization of each virtual machine through mixed deployment services

Abstract

The invention discloses a method and device for an elastic extensible virtual machine cluster. A specific embodiment of the method includes: when arranging a service, calculating first left resource quantity of virtual machines in the virtual machine cluster; acquiring resource demand of the to-be-arranged service; acquiring configuration grade of the virtual machines in the virtual machine cluster; according to whether the first left resource quantity meets the resource demand or not, determining a virtual machine with a preset configuration grade as a target virtual machine; arranging the to-be-arranged service to the target virtual machine. By the embodiment, the service can be arranged in the virtual machine cluster including different configuration grades, and different services can be arranged on a single virtual machine in a mixed manner, so that service arranging cost is lowered, and resource utilization rate of the virtual machine cluster is increased.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of Internet technology, and in particular to a method and device for elastically scaling virtual machine clusters. Background technique [0002] Elastic scaling of virtual machine clusters, that is, add virtual machines to the cluster when needed, or replace the original virtual machines with higher configuration virtual machines, delete virtual machines from the cluster when not needed, or use low configuration virtual machines Replace the original virtual machine, so as to achieve the purpose of reducing the cost of the entire virtual machine cluster and improve the input-output ratio of the virtual machine cluster. [0003] In the prior art, the configuration levels of the virtual machines in the virtual machine cluster are exactly the same, and the elastic scaling of the cluster is usually realized by monitoring the status of the cluster and adaptively a...
