Abstract

The invention provides an evaluation method and device of elastic property, and relates to the technical field of the cloud computation. The method comprises the following steps: detecting the CPU usage rate of a detected server at the current moment; controlling a load generator to increase the load at the detected server under the situation that the detected CPU usage rage is greater than the preset threshold value, thereby triggering the detected server to start the elastic scheduling strategy; acquiring an elastic scheduling parameter in the process of starting the elastic scheduling strategy by the detected server, wherein the elastic scheduling parameter comprises the elastic scheduling time of the elastic scheduling strategy; and determining the elastic expansion capability of the detected server based on the elastic scheduling parameter. A technical problem that the testing way of the elastic property is poor in accuracy in the prior art is relieved.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method and device for evaluating elastic capabilities. Background technique [0002] Elasticity refers to the ability of a server (for example, a cloud server) to elastically expand virtual resources based on the current CPU usage. [0003] With the rapid development of cloud computing technology, the computing data of cloud computing is gradually increasing, which requires the cloud server to have better scheduling and expansion capabilities to ensure the service quality of the cloud server. [0004] Based on this, it is particularly important to test the elasticity of cloud servers. Relevant technical personnel have also carried out related tests on the elasticity of the cloud server. However, the test process is realized by setting the relevant elasticity indicators for the cloud server. Accuracy is poor. Contents of the invention [0005] In view of this, the p...
