System and method for displaying and operating multiple layered item list in web browser with support of concurrent users

摘要

Support of end-user to view and operate computing resources through logically organized and graphically represented multi-layered item list (“hierarchical list”) has been fully realized on native window based computer user work environment with modern operating system such as Windows Explore of Microsoft. The present invention has implemented the hierarchical list to represent structured resources, such as for a central controlled distributed scalable virtual machine (CCDSVM), and to be displayable and operable via a browser on an end-user device for user to access and manage the actual structured resources. The implementation of the hierarchical list is accomplished by creating the hierarchical list in memory to mirror the actual structure resource, where the mirrored hierarchical list is sent to the end-user device, where the end-user device executes the browser to display the hierarchical list to allow the user to access the actual structured resources via the displayed hierarchical list.
