Embodiment Construction

[0052] Below in conjunction with accompanying drawing, describe technical scheme of the present invention in detail:

[0053] Because the traditional round-robin method and weighted round-robin method cannot well solve the matching between the idle resources of the platform host and the resources required by the virtual machine, it is easy to cause the problem of unbalanced load on the host nodes of the cloud platform. Although the minimum load first method can easily achieve load balancing of platform host nodes when selecting target hosts, it may have the problem of low overall resource utilization of the platform. The local search algorithm can achieve a more optimal process between load balancing and resource utilization, but there is a time-complex problem in selecting an algorithm. Aiming at the limitations of existing target host selection methods, the present invention proposes a target host optimization method based on a two-dimensional linked list of available resour...

Abstract

The invention relates to a cloud platform technology, in particular to a resource scheduling model and target host selection method during virtual machine deployment in a cloud platform environment. According to the target host optimal selection method based on an available resource two-dimensional chain table, a target host candidate set can be quickly positioned in the available resource two-dimensional chain table in accordance with the resource demand for virtual machine deployment, a target host is searched for in the small range candidate set, and accordingly the selection speed of the target host can be increased. By means of the target host selection method, the host selection strategy and the host selection algorithm are also improved, a user can flexibly choose to deploy a virtual machine based on a rapid mode or based on a load balancing mode, the most appropriate target host can be optimally selected to deploy the virtual machine through the selection algorithm, and the load balance requirement between platform hosts is met. The target host selection method is particularly suitable for target host selection in virtual machine deployment under the cloud platform environment.

Description

technical field [0001] The invention belongs to cloud platform technology, and in particular relates to a resource scheduling model and a method for selecting a target host when a virtual machine is deployed in a cloud platform environment. Background technique [0002] Cloud computing (Cloud computing) is a technology direction that has emerged in recent years, and it is also a research hotspot in the field of information technology. Cloud computing provides users with on-demand, scalable distributed resource services through the network. For example, the IaaS cloud platform system virtualizes the data center server hardware resources into a unified virtual machine resource pool, and then uses the virtualization management platform to provide all resources in the system to users through the network according to actual needs or other strategies. Because cloud computing realizes the unified management of computer resources, users are no longer responsible for the management ...
