Private Cloud System And Its Performance Analysis

With the rapid development of cloud computing technology, the use of cloud computing has received more and more attention. The applications of cloud computing emerge in endlessly, and this greatly improves the utilization rate of resources. The public cloud computing services provided by several large companies have also spawned a large number of successful innovative applications. But most companies hold a wait-and-see attitude to cloud computing. They have serious doubts about the cloud computing security. These companies are eager to use cloud computing to raise the utilization rate of resources, reduce the cost and ensure the data security and service stability at the same time. Therefore, this paper chose the private cloud computing technology which balances these two aspects as the research focus.Firstly, we carry out a systematic research and summary on the background and development of the cloud computing technology, and analyze its advantages. And then, we analyze and sort the key technologies involved in the cloud computing system. Then, we analyze three popular cloud computing software, including the software architecture, technical support, secondary development, installation and management and safety etc... On this basis, we build a private cloud computing system use ConVirt, and then we validate and analyze its advantages and disadvantages. Finally, we test the performance of this system through deploying an application. And this proves the usability of the private cloud computing system.Because the cloud computing technology is the trend of IT technology, so this paper focuses on to analyze and test the private cloud computing technology which can meet the general requirements of companies. The results of the test show that, the private cloud computing system can raise the utilization rate of resources, reduce the cost and help companies to have a flexible deployment compared with the traditional system.
