Abstract

Applications and services are accessed over the Web without requiring any modification to the currently available code for such applications. Virtual machines (VMs) can each be associated with one or more pre-configured and pre-installed software applications and hosted by Web sites. A VM is accessed and run when a user of a client computing device selects a Web object for the VM in a browser program. A plug-in in the browser reads a configuration file for the selected VM from a server and requests a server-side controller daemon to launch the VM on the server. The plug-in then opens a remote desktop connection to the VM, which is displayed as an embedded window in the Web page on the browser program. The user can then interact with and use the VM and its provided application software and services from within the browser program.

Claims
