Abstract

A management system for virtual applications may deploy sets of virtual applications to many client devices, dynamically allocate virtual application servers to individual clients, manage updates to the virtual applications, and provide other high level management to deployments of virtual applications. A client device may include a virtual application management client that may communicate with a management server. The management client may add or remove virtual applications to the client device based on a policy received from the management server, and may query the management server to determine a currently available virtual application distribution server when a virtual application is requested. The management server may distribute and manage versions of applications across one or more virtual application distribution servers.

Claims

1. A method comprising:

receiving a first request for a virtual application;

determining if a first portion of said virtual application is in a local cache;

executing said first portion of said virtual application;

connecting to a first virtual application server;

receiving a second portion of said virtual application; and

executing said second portion of said virtual application.

2. The method of claim 1, said first portion being obtained from a second virtual application server.

3. The method of claim 1, said second portion of said virtual application being obtained by streaming.

4. The method of claim 1, said first portion of said virtual application being obtained by a downloading mechanism.

5. The method of claim 1, said second portion being received in response to a request for said second portion.

6. The method of claim 1 further comprising:

receiving metadata concerning a plurality of virtual applications; and

selecting said first virtual application based on said metadata.

7. The method of claim 6, said selecting being based at least in part on a first proximity to said first virtual application server.

8. The method of claim 6, said selecting being based at least in part on a performance parameter.

9. The method of claim 8, said performance parameter being network bandwidth.

10. A client device comprising:

a management connector configured to send a request to a management server for a virtual application server, said request comprising an indicator for a first virtual application, said management connector further configured to receive an address for said virtual application server;

a virtual application connector configured to use said address for said virtual application server to establish a connection to said virtual application server and download at least a portion of said first virtual application; and

a virtual application runtime environment configured to execute said portion of said first virtual application in a virtual manner.

11. The client device of claim 10, said request further comprising at least one configuration parameter.

12. The client device of claim 11, said configuration parameter comprising an indicator that said first virtual application is to be streamed from said virtual server.

13. The client device of claim 10, said request further comprising at least one performance parameter.

14. The client device of claim 13, said performance parameter comprising available network bandwidth.

15. A management server device comprising:

a client connector configured to receive a request for a virtual application server from a client device; and

a server manager configured to select one of a plurality of virtual application servers in response to said request;

said client connector further configured to transmit an address for said one of said plurality of virtual application servers to said client device.

16. The management server device of claim 15, said request comprising at least one performance parameter relating to said client device.

17. The management server device of claim 15 further comprising:

a monitor configured to communicate with said plurality of virtual application servers and collect status information from each of said plurality of virtual application servers.

18. The management server device of claim 17, said status information comprising an inventory of virtual applications.

19. The management server device of claim 17, said status information comprising performance parameters from at least one of said plurality of virtual application servers.

20. The management server device of claim 15, said server manager further configured to perform an optimization calculation to select said one of said plurality of virtual servers.
