The Design And Implement Of Private Cloud Base On Open Stack

Cloud computing, a business computing model developed from grid computing, parallel computing and decentralized computing, has grasped a rapid development in recent years. From a narrow perspective, cloud computing refers to the delivery and pattern of utilization of IT infrastrucure, that is, to acquire the resources according to users’ need. In a broad perspective, however, cloud computing refers to the delivery and pattern of utilization of service, which means to acquire the wanted service through the Internet. The Internet to provide resource is entitled “cloud”, whose capacity of computing is determined by a large scale of cluster and the building of virtualization. It has fundamentally influenced and changed the way people use the computing resources as well as the structure of the whole industry.The paper built an Iaa S private cloud computing platform according to the study of the concept and key technology of cloud computing. It was based on the hottest open source cloud management software “Open Stack” at present, structuralized a cloud computing construction for users’ service based on infrastrucure and summed up six functional modules. The six functional modules refers to virtual machine module, security module, image module, trend prediction module, physical host module and monitor module.The platform used Web management system as a entrance, provided a favorable interactive interface to users, realized the flexible management of physical resources and virtual machine resources and raised the fault tolerance by means of image backups mechanism. In addition, the platform also owned an integrated monitor and auto-predict system which showed great significance in resources distribution and recycling to evaluate the service and to optimize the resources use ratio.
