With the increasingly mature network technology and the rapid development of E-commerce, in 3G Mobile internet and information hard demand driven, IaaS Cloud management platform is to apply the concept of cloud computing to the Internet Data Center (IDC) A new kind of cloud management platform. In the IaaS Cloud management platform The virtual network management system uses the Java EE architecture MVC design pattern. Database server using Oracle database databases, its high reliability, high scalability features will provide a solid foundation for the stable operation of the system. The application server selects IBM's WebSphere Creator server. The client employs Internet Explorer, which is currently widely available. This thesis first expounds the development methods and related technologies used in cloud management platform system, And through to the domestic cloud application market demand analysis and the Cloud Management Platform system function analysis thorough research, the three functions of virtual network management system in cloud management platform system are designed and implemented: 1. Network management: the creation and maintenance of basic network and subnet, including public network, private network and office network, Enable the administrator to allocate a large number of virtual machines to the above different virtual networks, to achieve different customer needs. 2. Security rules: Network isolation, the administrator to the various VMS to configure different security rules to achieve the virtual machine communication control function. 3.NAT address mapping: By establishing the static mapping between the internal address and the external address, the virtual machine's access function to the public network is realized. Through the development of the above functions, it has successfully solved the network management problem of virtual machines and other virtualization devices, improved the security of cloud management platform, and laid the foundation for further developing and perfecting cloud management platform system.
