2 Cloud computing platform designThe virtualization layer is designed primarily by using an open source infrastructure cloud service management software, Eucalyptus. The virtualization layer needs to choose the right node because it is a key layer in the entire platform. The resource pool layer selects resources from the pooled resource pool layer and packages them to form computing resources of different sizes according to the needs of users or services, thus obtaining the virtual machine that we are most familiar with [8]. At the virtualization layer, Eucalyptus, an open source software for managing the infrastructure cloud service platform, is used, and the node control components of Eucalyptus, which can perform shutdown, check, start, and cleanup., are installed on them. In order to access the underlying virtualization layer and virtual resources, it is necessary to install the corresponding components on the two servers deployed on the management layer. In addition, management ultimately translates the corresponding requests from the service layer into access to virtual resources. On the issue of installing a deployment server, one server installs the cloud controller component and the other installs a cluster controller component and a storage control component with nodes that connect the connection service layer and the virtualization layer. The overall architecture of the design is shown in Figure 1 [9].
