Problems solved by technology

However, the service goals proposed by users are somewhat ambiguous. The service level agreement provided by the service cloud resource end can only be used as the minimum realization threshold of the service provided by the service cloud. The system cannot directly use these data to predict possible resource requests. , and perform effective service cloud resource allocation

Embodiment Construction

[0044] The implementation of the technical solution is described in further detail below:

[0045] Step 1: Initialize the current resource-side SLA threshold

[0046] In this step, the resource side of the service cloud submits its SLA template and threshold to establish the background data that needs to reserve resources to create a virtual machine. This data is the service level agreement data submitted by the service cloud and recorded as SLA pub ={p 1 ,p 2 ,...,p n}, where p nIndicates the nth service level target to be achieved by the announced SLA, SLA pub The superscript pub in indicates that the service cloud is published on the network. The SLA vector is regarded as the SLA warning value given by the cloud resource provider. When the warning value is exceeded, the cloud resource provider needs to adjust its virtual machine resources. To meet the commitment given by oneself to the task;

[0047] At the same time, the metric (Metric) of the SLA vector also forms a...

Abstract

The invention relates to a method for implementing forecasting on the requirement of a virtual machine on the basis of service level agreement constraints, which is used for implementing forecasting on the resource requirement of the virtual machine in a mode of carrying out analysis on the SLA (service level agreement) constraints of a task in a current service cloud so as to conveniently reserve resources. By carrying out prejudgment, feedback forecasting and breakthrough probability forecasting on a resource end of the current service cloud, forecasting on the resource requirement of the virtual machine is implemented and the resources required by the current virtual machine are reserved, so that cost of dispatching the virtual machine at the resource end of the cloud is reduced. The invention belongs to the field of a cloud computing and innovation network. The method for forecasting the requirement of the virtual machine, which is designed by the invention, can be applied to a resource providing end in the service cloud to implement resource reservation on an IaaS (Infrastructure As A Service) layer; meanwhile, an algorithm is simple and easy to implement.

Description

technical field [0001] The invention relates to a method for predicting the demand of a virtual machine, a method for analyzing the SLA constraints of tasks in the current service cloud, and realizing the prediction of the resource demand of the virtual machine to facilitate resource reservation. Through the prediction, feedback prediction and breakthrough probability prediction of the current service cloud resource end, the demand prediction of virtual machine resources is realized, the resources required by the current virtual machine are reserved, and the overhead of virtual machine scheduling on the cloud resource end is reduced. The invention belongs to the field of cloud computing and innovation network. Background technique [0002] The reservation of service cloud resources is an important step to realize efficient cloud resource services. However, the service goals proposed by users are somewhat ambiguous. The service level agreement provided by the service cloud r...
