雲端計算是近幾年來相當熱門的話題。如何將雲端系統使用在大型計算、建置大型分散式儲存叢集以及提供服務，是現在非常熱門且熱烈的討論議題，不論是對企業或是個人都是一個必然的趨勢。雲端實際上是指網路，這個名字來自工程師在示意圖，往往用雲代表了一個網路。而雲端的網路服務大致可分為三種：軟體即服務（SaaS）、平台即服務（PaaS）和基礎設施即服務（IaaS）。在這些類型中，軟體即服務(SaaS)允許用戶從雲遠程運行應用程序。平台即服務（PaaS）包括作業系統與自定義特定的應用軟體。基礎設施即服務（IaaS）是指計算資源作為服務，包括虛擬化機器的部分和硬體資源單位。本論文主要研究方向在於如何在雲端環境上建置KVM系統並運作，並使用KVM提供虛擬環境給使用者申請使用。在使用者介面部分，我們考量到降低使用者操作界面的複雜性，針對使用者部分我們採用淺顯易懂網頁介面，讓使用者在操作上無障礙。在實驗部分，本文比較了實體機器運算效能與KVM運算效能，並分析實驗結果。 Cloud computing is a very hot topic in recent years. How will the system be used in large-scale cloud computing, to build large-scale distributed storage cluster and the provision of services is now very popular and lively discussion of the question, whether the enterprise or the individual is an inevitable trend. Actually refers to the network cloud, the name comes from the engineers in the diagram, often represented by a network cloud. The cloud of network services can be divided into three types: Software as a Service (SaaS), Platform as a Service (PaaS) and infrastructure as a service (IaaS). In these types, the Software as a Service (SaaS) allows users to run applications remotely from the cloud. Platform as a Service (PaaS), including the operating system and custom application-specific software. Infrastructure as a Service (IaaS) is the computing resources as a service, including some virtual machines, hardware resource units. This thesis research is how to build the KVM environment in the cloud system and operation, and use the KVM provides a virtual environment to the user to apply. In the user interface part, this work can reduce the complexity of cloud resources accessing for the user part. This thesis uses the web interface that is easy to understand, accessible for users in the operations. In the experimental results, this work compares the performance of physical machine and KVM virtual machine, and analyzes the results.
