With the requirements of wide-area sharing of various kinds of manufacturing related software,a prototype of cloud manufacturing platform was developed for the purpose of software resource management and sharing,which was mainly based on the technologies of cloud computing-virtualization and SaaS,etc.A cluster of virtual machines,which can be dynamically managed,was established on VI3 infrastructure. Similar to the structure of Google file system(GFS),large amounts of software resources were organized and well-managed.Upon the .Net structure,and with PowerShell technology,a remote invocation of the application software was realized for the web-based remote user.Finally,for the design of motor product,the process of remote use of an electromagnetic-software was demonstrated based on the cloud manufacturing platform.
