【摘要】：進(jìn)入新世紀(jì)以來，信息技術(shù)和IT產(chǎn)業(yè)發(fā)展的十分迅速，傳統(tǒng)的計算模式已經(jīng)很難去適應(yīng)不斷增長的數(shù)據(jù)處理的需求，因此需要一種新型的、高效的計算模式。云計算能夠提供通用的高效計算平臺和存儲空間，是大數(shù)據(jù)時代有效的數(shù)據(jù)計算解決手段，并且能夠大幅度節(jié)省成本。 但是，隨著云計算平臺的大力發(fā)展和普及，也帶來了很多新的問題，其中對云平臺的性能方面的評測是其中至關(guān)重要的一個方面。由于與傳統(tǒng)計算平臺相比，云平臺的復(fù)雜程度要更高，規(guī)模也更龐大，因此對云平臺的性能測試是一項很困難的任務(wù)。目前針對云平臺性能測試已有的研究成果中，很多都只是針對云平臺性能的某一個方面的測試且測試方法比較單一，需要更加深入的研究與完善。 本文通過深入研究云平臺的架構(gòu)，結(jié)合云平臺的特征，提出了從3個層次對云平臺進(jìn)行性能測試——分別測試云平臺的虛擬化性能、資源管理能力和服務(wù)提供能力。分別對應(yīng)云平臺的虛擬資源層、平臺管理層和應(yīng)用服務(wù)接口層。在每個層次分別設(shè)置了若干測試項目和相應(yīng)的測試指標(biāo)，，針對每個測試項目也研究了相應(yīng)的性能測試工具。 為了研究針對云平臺的性能評測方法，本文搭建了兩個典型的云平臺——VMware vSphere平臺和CloudStack平臺，并結(jié)合之前提出的3個測試層次和測試指標(biāo)選用合適的測試工具在兩個平臺上進(jìn)行了對比測試。此外，本文為了評價云平臺服務(wù)提供能力，實現(xiàn)了一套基于LoadRunner的負(fù)載測試工具，可以模擬多個并發(fā)虛擬用戶對云平臺進(jìn)行負(fù)載測試。
[Abstract]:With the rapid development of information technology and IT industry in the new century, it is difficult for the traditional computing mode to adapt to the increasing demand of data processing. Therefore, a new and efficient computing mode is needed. Cloud computing can provide general efficient computing platform and storage space, is an effective data computing solution in big data era, and can greatly save costs. However, with the development and popularization of cloud computing platform, there are many new problems, among which the evaluation of cloud platform performance is one of the most important aspects. Compared with the traditional computing platform, the cloud platform is more complex and larger, so it is a difficult task to test the performance of the cloud platform. At present, among the existing research results of cloud platform performance testing, many are only aimed at a certain aspect of cloud platform performance testing, and the test method is relatively single, which needs more in-depth research and improvement. Based on the research of the cloud platform architecture and the characteristics of the cloud platform, this paper proposes three levels of cloud platform performance testing, namely, the virtualization performance, resource management capability and service delivery capability of the cloud platform. Corresponding cloud platform virtual resource layer, platform management and application service interface layer. Several test items and corresponding test indexes are set up at each level, and the corresponding performance testing tools are also studied for each test project. In order to study the performance evaluation method of cloud platform, this paper builds two typical cloud platforms-VMware vSphere platform and CloudStack platform. Combined with the three test levels and test indexes proposed before, the appropriate test tools were selected to carry out the comparative tests on the two platforms. In addition, in order to evaluate the service supply ability of cloud platform, this paper implements a load testing tool based on LoadRunner, which can simulate multiple concurrent virtual users to test the load of cloud platform.
