[0103] ●Problem description and optimization goals
[0104] The VM virtual machine deployment problem is described as follows: n sets of VM application requests, denoted as Qi=q 1 ,q 2 ,q 3 ,...,q n , where q i ={sc i , sm i ,sh i , sn i}Represents the configuration of the VM virtual machine, where sc i is the CPU size, sm i is the memory size, sh i is disk space, sn i is the expected bandwidth.
[0105] The set of m host machines on the cloud platform P=p 1 ,p 2 ,p 3 ,...,p m |m∈N, where pi={SC i , SM i , SH i , SN i} indicates the configuration of the host pi, where SC i is the CPU size, SM i is the memory size, SH i is disk space, SN i for the available bandwidth. P is divided into n groups,}P=Gi|i∈(0,n), and Gi represents the i-th group of hosts.
[0106] When the management layer submits a virtual machine application request to the system, the virtual machine deployment scheduling policy establishes the mapping from the virtual machine to the host...

[0229] Such as Figure 8 As shown, a system using a performance-weighted virtual resource dynamic management policy method under a cloud platform, the system includes: a client layer, a platform management layer and a virtual resource pool layer. The virtual resource pool layer includes a central controller, a central controller, a virtual machine monitor, a cluster controller, a storage controller, and a central manager. in,
[0230] The client layer is used to request virtual machine services from the system;
[0231] The central controller, the core processor of the system, is the main controller component, responsible for managing the entire system, specifically responsible for processing various requests from users and internal components of the system, and processing them according to the corresponding management policies. The central controller includes a set of services for processing various requests, verifying and maintaining system and user metadata, taking charge...

Abstract
The invention relates to the technical field of cloud computing, in particular to a performance-weighted virtual resource dynamic management policy method under a cloud platform. The present invention first configures a comparison matrix of various request resources and performance weights, and proposes a load performance measurement model based on load performance weighting based on user needs and real-time monitoring data of the cloud platform system, and then proposes a virtual cloud platform based on the model. Resource dynamic management strategy method, which includes virtual machine deployment strategy and virtual machine migration strategy, so that the cloud platform can ensure that the load level of the physical server of each scheduling domain is maximized under the condition of satisfying the existing load request, and on this basis On the one hand, minimize the number of physical services that need to be opened on the cloud platform. The invention of the method can simultaneously consider the needs of users and provide personalized weight setting and real-time performance monitoring data of the cloud platform system, which not only meets the QoS requirement, but also reasonably utilizes the system resources of the cloud platform to ensure the load performance of the cloud platform.
Description
technical field [0001] The invention relates to the technical field of cloud computing, in particular to a performance-weighted virtual resource dynamic management policy method under a cloud platform. Background technique [0002] Cloud computing is a computing method that provides resources to customers in the form of "services" through the Internet. All these services are provided in the form of Internet resource pools in an elastic, on-demand, and billing manner. [0003] Virtualization is one of the key technologies to realize these features, and how to effectively deploy virtual machines is a key technology for IT resource sharing pool management. In a cloud computing environment, users generally require its operation to be stable, and do not want frequent migration of virtual machines. Therefore, the centralized virtual machine optimal deployment method has always been a hot spot in current technical research. [0004] The deployment of the virtual machine mainly co...
