【摘要】：針對現(xiàn)階段使用私有云評測方法缺失所導致搭建私有云供需不匹配的問題,提出了一種自適應、可擴展的私有云系統(tǒng)能力檢測方法,可對基礎設施即服務(IaaS)云計算系統(tǒng)能力進行評測。首先,通過私有云應用程序接口動態(tài)擴展虛擬機數(shù)量;然后,通過性能特征模型選取虛擬機所需配置的硬件信息和操作系統(tǒng)類別,并根據(jù)用戶的需求差異使用不同的負載模型,形成相應的模擬運行環(huán)境;最后,使用云計算服務等級協(xié)議(SLA)作為測試標準來衡量私有云服務能力。使用所提方法對Openstack開源私有云平臺的能力進行了評測,實驗結(jié)果表明,所提方法可以準確得出私有云服務能力,結(jié)果和用戶實測一致。該方法負載生成成本更低,測試效率更高。并將該方法與Openstack自帶的組件Rally進行對比,拓展性和負載動態(tài)模擬有很大的改進。
[Abstract]:Aiming at the mismatch between supply and demand of private cloud due to the lack of private cloud evaluation method at present, an adaptive and extensible method for detecting the capability of private cloud system is proposed. The capability of infrastructure as a service (IaaS) cloud computing system can be evaluated. Firstly, the number of virtual machines is dynamically extended through the private cloud application program interface. Then, the hardware information and operating system categories of virtual machine are selected through the performance feature model, and different load models are used according to the user's demand difference to form the corresponding simulation running environment. Finally, the private cloud service capability is measured using cloud service level protocol (SLA) as a test standard. The proposed method is used to evaluate the capability of Openstack open source private cloud platform. The experimental results show that the proposed method can accurately obtain the private cloud service capability, and the results are consistent with user measurements. The load generation cost of the method is lower and the test efficiency is higher. The method is compared with the component Rally of Openstack, and the expansibility and load dynamic simulation are greatly improved.
