Abstract

The invention belongs to the technical field of cloud computing and networks, and particularly relates to a Web multilayer application dynamic resource adjustment method based on IaaS layer application perception. The Web multilayer application dynamic resource adjustment method based on IaaS layer application perception includes the steps that an IaaS cloud platform perceives a Web multilayer application framework, namely application management and information maintenance are added on the basis of traditional IaaS management so that the state of a Web multilayer application above the IaaS layer can be perceived; dynamic resource demand quantitative evaluation is carried out on the basis of perception, namely, modeling is carried out firstly, and then a quantitative analysis method and an algorithm of dynamic resource demands of the Web multilayer application are provided; dynamic resource adjustment is carried out on the basis of application load perception, namely when the load of the Web multilayer application changes, the resource demands are detected out in time and quantified, and a response is given so that resource allocation can be adjusted dynamically. The resource allocation of a virtual machine is optimized and adjusted under the situation of not affecting application performance, potential resource waste is avoided, and the overall resource utilization rate of a data center is increased.

Description

technical field [0001] The invention belongs to the field of cloud computing and novel network technologies, and in particular relates to a method for adjusting dynamic resources of Web multi-layer applications. Background technique [0002] In recent years, cloud computing has attracted more and more attention due to its characteristics of dynamic allocation, elastic expansion, resource sharing, and pay-as-you-go. The emergence of cloud computing has not only changed the architectural model of today's IT infrastructure, but also changed the way cloud service users obtain IT resources, and cloud service providers manage and provide software, technology and solutions. [0003] While cloud computing brings convenience to enterprises and users, it also poses many challenges to cloud platform managers. For the IaaS cloud, the primary task of the cloud platform is to meet the user's resource requirements. In addition, how to allocate and use resources more reasonably from the da...
