摘要: | 隨著硬體及網路的進步,1966年提出的運算資源即是公用資源的概念(Computing as a Utility),終於得以實現,並在近年內取得了商業上的矚目,它即是現今的雲端運算。雲端運算提供了一個嶄新的IT服務模型──應用程式及服務供應商不需要自行購置數據中心,轉而向雲端供應商依需求租賃運算資源。然而,現今雲端供應商眾多,各家的硬體資源及計價方式都不盡相同,在缺乏標準化及資訊不公開的情況下,雲端使用者難以比較不同的雲端服務的效能及價格,並確保雲端的移植確實帶來成本的節約。在此等前提下,對一個欲將自身Web應用程式移植至雲端平台的使用者來說,如何依程式的特性,來選擇適當的雲端平台,是一件困難的事。本研究致力於提供一套成本及效能導向的工具組,依程式的特性及使用者的效能品質需求,來選擇適當的雲端平台及預測所需要的部署成本。 With cloud business gowning, many companies are joining the market to be a cloud service provider. Most providers offer similar services with slightly different charging models, and very little known performance comparison between them is published. This leaves cloud service users with the puzzle of guessing what cost they will need to pay to run their legacy application in a cloud environment. CloudGuide is a tool suite that provides user an estimated cost of running a legacy application with QoS guarantee on different cloud providers. CloudGuide predicts the cloud computing resources required by a targeted application based on queuing model, meanwhile estimates monetary deployment cost for the application. CloudGuide also allows the user to explore cloud configuration can guarantee different levels of QoS. In our evaluation, we conducted experiments of a multi-tiered network application, RUBiS, and showed that CloudGuide can choose cloud configuration that guarantee QoS and provide cost estimation. |
