Abstract

In a first embodiment of the present invention, a method is provided comprising: determining if a portion of a script of web application code within a web application is migratable to a remote infrastructure, wherein the portion of the script contains one or more functions; and modifying the portion of the script if the portion of the script is migratable, such that execution of the portion of the script results in the one or more functions being executed on the remote infrastructure, wherein the remote infrastructure is not restricted to the device on which the web application was designed or distributed.

Claims

1. A method comprising:

determining if a portion of a script of web application code within a web application is migratable to a remote infrastructure, wherein the portion of the script contains one or more functions; and

modifying the portion of the script if the portion of the script is migratable, such that execution of the portion of the script results in the one or more functions being executed on the remote infrastructure, wherein the remote infrastructure is not a device on which the web application was designed or distributed.

2. The method of claim 1, wherein the determining and modifying are performed upon launch of the web application.

3. The method of claim 1, wherein the determining includes examining the script to identify whether one or more functions have been identified within the script as migratable.

4. The method of claim 3, wherein one or more functions are identified as migratable if they are contained in a script section that is identified as migratable.

5. The method of claim 3, wherein one or more functions are identified as migratable if they each individually are identified as migratable using a web application script extension.

6. The method of claim 3, wherein one or more functions are identified as migratable if they each individually are not identified as non-migratable using a web application script extension.

7. A method for launching a web application on a client device, wherein the web application includes web application code script, the method comprising:

retrieving one or more functions from the web application code script that have been identified as migratable;

for each of the one or more functions;

sending a copy of the function to a remote infrastructure;

receiving a web address from the remote infrastructure, wherein the web address is such that, upon invocation, the remote infrastructure runs the copy of the function; and

creating a stub function containing the web address, such that when the stub function is executed by the client device, the web address is invoked.

8. The method of claim 7, wherein the remote infrastructure is a computer server.

9. The method of claim 8, wherein the remote infrastructure is a plurality of computer servers grouped as a cloud.

10. The method of claim 8, wherein the remote infrastructure is another client device.

11. The method of claim 8, wherein the remote infrastructure is a group of client devices.

12. The method of claim 7, further comprising:

selecting a remote infrastructure to which to send the copy of the function by examining a preconfigured list of remote infrastructures and randomly selecting one that is currently available.

13. The method of claim 7, further comprising:

selecting a remote infrastructure to which to send the copy of the function by scanning for available remote infrastructures in a network.

14. A method for executing a web application on a client device, wherein the web application includes web application code script, the method comprising:

retrieving one or more functions from the web application code script that have been identified as migratable;

for each of the one or more functions;

sending a copy of the function to a remote infrastructure for execution; and

receiving results of the execution from the remote infrastructure.

15. A method for executing a web application function on a client device, the method comprising:

receiving a call of a stub function from a software program, wherein the stub function has an identical signature to the web application function, wherein the stub function contains a web address of a remote function on a remote infrastructure;

invoking the web address in order to cause the remote infrastructure to run the remote function;

receiving values computed during the remote infrastructures running of the remote function; and

passing the values to the software program as if the client device had run the web application function.

16. The method of claim 15, wherein the remote infrastructure includes computer devices controlled by a user of the client device.

17. A method for loading a web application function in a remote infrastructure, the method comprising:

receiving a copy of a web application function from a remote connection manager of a client device;

loading the copy of the web application function for running;

creating a web address corresponding to the copy of the web application function, wherein the web address is such that, upon invocation at the client device, the copy of the web application function is run by the web application environment; and

sending the web address to the client device.

18. The method of claim 17, wherein the remote infrastructure is distinct from a server from which the web application function was obtained by the client device.

19. The method of claim 17, further comprising:

executing the code of the web application function.

20. An extended browser comprising:

a source code analyzer configured to examine web application script to determine if functions within the web application script are migratable;

a source code manager configured to, for any functions that are migratable, create a stub function containing a remote function call; and

a remote connection manager configured to pass a copy of any functions that are migratable to a remote infrastructure, receive a web address for each of the remote functions from the remote infrastructure, and pass the web addresses to the source code manager; and

wherein the source code manager is further configured to insert the web addresses into corresponding stub functions such that, upon execution of a stub function, a corresponding web address is invoked such that the remote infrastructure runs a corresponding remote function and returns the results.

21. The extended browser of claim 20, wherein the stub function has only a single command in a body of the stub function, the single command being a command to invoke the web address for the corresponding remote function.

22. An apparatus comprising:

a web application environment configured to;

receive a copy of a web application function from a remote connection manager of a client device;

load the copy of the web application function for running;

create a web address corresponding to the copy of the web application function, wherein the web address is such that, upon invocation at the client device, the copy of the web application function is run by the web application environment; and

send the web address to the client device.

23. The apparatus of claim 22, wherein the apparatus is a server farm.

24. An apparatus comprising:

means for determining if a portion of a script of web application code within a web application is migratable to a remote infrastructure, wherein the portion of the script contains one or more functions; and

means for modifying the portion of the script if the portion of the script is migratable, such that execution of the portion of the script results in the one or more functions being executed on the remote infrastructure, wherein the remote infrastructure is not a device on which the web application was designed or distributed.

25. A program storage device readable by a machine tangibly embodying a program of instructions executable by the machine to perform a method comprising:

determining if a portion of a script of web application code within a web application is migratable to a remote infrastructure, wherein the portion of the script contains one or more functions; and

modifying the portion of the script if the portion of the script is migratable, such that execution of the portion of the script results in the one or more functions being executed on the remote infrastructure, wherein the remote infrastructure is not a device on which the web application was designed or distributed.
