Problems solved by technology

As the number of tasks and user traffic increase, most of the load will be added to a single server. Simply expanding the cluster will not make full use of resources and the task distribution will be uneven.

Abstract

The invention relates to a dynamic resource scheduling method based on OpenStack, and belongs to the field of resource scheduling algorithms. According to the algorithm, a virtual machine migration triggering strategy is set, the migration triggering conditions of a virtual machine are mainly divided into two types, namely migration triggered by an upper limit threshold and migration triggered bya lower limit threshold. The two triggering conditions are mainly considered from two different aspects, wherein the setting of the upper limit threshold is used for avoiding the overhigh node load, the inability of meeting user needs or the operation fault of the node due to overhigh load. A Ceilometer module of the OpenStack is used for acquiring each load attribute value and the consumption rate thereof of all physical servers. According to the method provided by the invention, the quantity of running nodes is reduced, the electric energy is saved, and the mistaken migration generated by instantaneous vibration is avoided.

Description

technical field [0001] The invention belongs to the field of resource scheduling algorithms, and relates to an OpenStack-based dynamic resource scheduling method. Background technique [0002] OpenStack is an open source cloud computing service platform that provides scalable and scalable cloud computing services for public clouds and private clouds. Any enterprise or individual can use OpenStack to build a private cloud platform to provide services, or build a public cloud platform to provide external cloud services. [0003] With the large-scale deployment of the OpenStack platform, thousands of physical nodes are deployed in the cloud data center, and different services and applications are running on these physical nodes, thus placing higher requirements on the OpenStack platform. In addition, an important research direction in the OpenStack field is the resource scheduling of OpenStack. Through the optimal scheduling of computing, network, storage and other resources i...
