Abstract: Starting from the actual requirements of general cloud platform and project, combining with the packet cluster architecture, and using CloudStack open source cloud platform, an experimental platform based on packet cluster mapping mechanism is  designed. The experimental platform adopts a layered design method, including hardware facilities layer, virtual resource layer, scheduling layer, middle layer of packet cluster, and user application layer, which converts the traditional application for resources in the form of virtual machine into the application in the form of demand packet, and the user can specify the structure of required packages and the physical resources required for each package. Through the analysis of the scheduling principle of the cloud platform, it is expounded how to apply the cluster deployment algorithm involved in the project to the experimental platform, which provides experimental basis for the research results of the subsequent improvement project. Finally, the six important management functions of the cloud computing management platform are selected. Through the overall functional test of experimental platform based on the clustering mechanism, CloudStack and OpenStack cloud management platforms, the results show that the clustered experimental platform in this paper provides comprehensive management functions and has certain application market.
