[Abstract]:The main content of this paper is that cloud computing is a huge change in the history of computer development after the 1980s large computer to the client - server. Since the concept of cloud computing was put forward by Google company in 2007, its connotation is developing continuously. As one of the cloud computing based on service types, IaaS is improved. The virtualization of infrastructure resources provides users with virtual computing resources including virtual machines, storage and network. Most of the existing IaaS layer cloud computing platforms in China are virtualization of hardware resources, resource management and deployment by using third party virtualization software. For example, the bottom of cloud pool in jump technology is Xen, K VM, Neusoft's cloud platform uses the core technology of Intel's cloud platform, and many enterprises have adopted a relatively open open open source cloud computing management project in the underlying technology, and so on. There are disadvantages in the development, technology and property rights of the platform. The cloud management platform in this paper is based on XenServer virtual. The open source IaaS cloud management platform of chemical technology. Through virtualization management software XenServer6.0 to realize the virtualization of the cloud management platform to physical resources, and use its open interface to complete the scheduling, management, monitoring and security of the resources in the platform. In addition, we hope to explore the platform of the x86 architecture across the XenServer through this work. Resources management and control methods. Through our research to get rid of the dependence on the third party virtualization technology, the research belongs to our own IaaS layer cloud computing platform, let the domestic cloud platform products have new breakthroughs in the underlying technology. With the global development of cloud computing, the cloud computing model in the near future will bring new technological innovation. We hope to develop an open source cloud management platform for IaaS layer to solve the above problems. In this paper, there are two main tasks to be completed, the first cloud management platform technology research. In order to reduce the coupling between the low cloud management platform modules, improve the performance of the platform and enhance the scalability of the cloud management platform, the tools tools provided by XenServer can implement the flat platform function of cloud management through its open interface, and try to carry out the resources directly across the XenServer. The final purpose of our research on cloud management platform is achieved. Second validation research results. The paper analyzes the data through the test of application cases to confirm the correctness of the above research results. The plan uses FritzChessBenchmark (international chess game), HA_HWiNF032 v3.56-870, and Sisoftware 2012 green Sinicization edition respectively. IozonV1.0 four test tools test the performance of the CPU, memory, network bandwidth and file reading and writing speed of the cloud management platform. For the final goal of the first research work, the following three techniques need to be studied in the research part of the cloud management platform function: first, the work is to try the OpenvSwitch standard. Realize the creation, modification and deletion of virtual network in cloud management platform, and realize communication between internal and external network in cloud management platform. Two, the technical feasibility study of virtual machine management monitoring technology VNC. Three, research on the mechanism of virtual machine deployment in XenServer to help us design high availability in the strategy. In the research of architecture, five levels of technical architecture are proposed, including service layer, management layer, data layer, virtualization layer and resource layer. The concept model of data center is borrowed from the network topology design. The logic function uses WebServer and CloudServer hierarchies to design ideas. And the Applet application is embedded in Flex through HTML. By analyzing the application mode of the virtual machine, this paper analyzes the application mode of IaaS, studies the deployment mechanism of the virtual machine at the bottom of the cloud management platform, defines the available CPU number and memory size of the computing node in the model to the two-dimensional queue, and completes the resource matching through the strategy of the priority matching of the computing unit, and improves the utilization of the computing node CPU. Finally, according to the above research contents, the experimental test scheme is proposed, and the test results are given to verify the feasibility of the above research contents.
