Abstract: A method for making a hypermedium page interactive, the hypermedium page displayed by a network browser, includes the step of selecting a hyperlink on the hypermedium page displayed on a client machine, the hyperlink identifying a desired computing resource. A hyperlink configuration file is retrieved, the hyperlink configuration file corresponding to the hyperlink and identifying a server machine. A client agent is started on the client machine. The client agent creates, via a terminal services session, a communication link to a virtual machine executing on the server identified by the hyperlink configuration file, the virtual machine executed by a hypervisor executing in the terminal services session provided by an operating system executing on the server. The client agent receives data from the virtual machine and displays, on the client machine, the received data without intervention by the network browser.

Abstract: A method for selecting a method of execution for an application includes the step of receiving credentials. A plurality of applications available to a client machine is enumerated responsive to the received credentials. A request to execute an enumerated application is received. One of a predetermined number of methods for executing the requested application is selected responsive to a policy, the predetermined number of methods including a method for executing the requested application in a computing environment provided by a virtual machine.

Abstract: A method for providing remote access to a computer environment provided by a virtual machine includes the step of receiving authentication information associated with a user of a client machine. Based on the received authentication information, a computer environment provided by a virtualized operating system and already associated with the user is identified. A connection is established between the client machine and the identified computing environment.

Abstract: A method for providing access to a computing environment includes the step of receiving a request from a client system for an enumeration of available computing environments. Collected data regarding available computing environments are accessed. Accessed data are transmitted to a client system, the accessed data indicating to the client system each computing environment available to a user of the client system. A request is received from the client system to access one of the computing environments. A connection is established between the client system and a virtual machine hosting the requested computing environment via a terminal services session, the virtual machine executed by a hypervisor executing in the terminal services session provided by an operating system executing on one of a plurality of execution machines.

Abstract: A method for providing access to a computing environment includes the step of receiving, by a broker machine, a request from a client machine for access to a computing environment, the request including an identification of a user of the client machine. One of a plurality of virtual machines is identified by a session management component, the identified virtual machine providing the requested computing environment. One of a plurality of execution machines is identified, the identified execution machine providing a terminal services session in which a hypervisor executes to provide access to hardware resources required by the identified virtual machine. The hypervisor launches the identified virtual machine. A connection is established between the client machine and the identified virtual machine, via the terminal services session.

Abstract: A system for granting access to resources includes a client machine, a collection agent, a policy engine, and a broker server. The client machine requests access to a resource. The collection agent gathers information about the client machine. The policy engine receives the gathered information and assigns one of a plurality of levels of access responsive to application of a policy to the received information. The broker server establishes, responsive to the assigned level of access, a connection between the client machine and a computing environment providing the requested resource, the computing environment provided by a virtual machine.

Abstract: A method for providing authorized remote access to a computing environment provided by a virtual machine, includes the step of requesting, by a client machine, access to a resource. A collection agent gathers information about the client machine. A policy engine receives the gathered information. The policy engine makes an access control decision based on the received information. A computing environment already associated with the user is identified in response to the received information, the identified computing environment provided by a virtual machine. A broker server establishes, responsive to the access control decision, a connection between the client machine and the identified computing environment.

Abstract: A method for executing, by a virtual machine, an application program requested by a client machine includes the step of receiving a file including access information for accessing a plurality of application files and for executing a first client capable of receiving an application stream. An identification of the plurality of application files is retrieved, responsive to the received file. At least one characteristic required for execution of the plurality of application files is retrieved, responsive to the file. A determination is made as to whether a client machine includes the at least one characteristic. A second client is executed, responsive to a determination that the client machine lacks the at least one characteristic, the second client requesting execution of the plurality of application files on a remote machine comprising a virtual machine providing a computing environment having the at least one characteristic.

Abstract: A system for incorporating remote windows from remote desktop environments into a local desktop environment comprises a first virtual channel coupled to a remote desktop environment provided by a virtual machine, a second virtual channel coupled to the remote desktop environment, and a local agent coupled to the remote desktop environment via the first and second virtual channels. The first virtual channel conveys graphical data associated with a remote window provided by the remote desktop environment. The second virtual channel conveys window attribute data associated with the remote window provided by the remote desktop environments. The local agent directs the formation of a local window in the local desktop environment corresponding to the remote window provided by the remote desktop environment, the first local window displaying the graphical data conveyed by the first virtual channel in accordance with the window attribute data conveyed by the second virtual channel.
