Abstract

The claimed subject matter provides a system and/or a method that facilitates re-locating a web application associated with a network service utilizing a portion of serialized data. The network service can be any collection of resources that are maintained by a party (e.g., third-party, off-site, etc.) and accessible by an identified user over a network (e.g., WAN, Internet, etc.). An interface component can receive a portion of serialized data with transparent structure related to an application specification. A hydrate component can create a web application independent of a network service based at least in part upon the serialized data, the web application has state within the network service.

Claims

1. A computing system, comprising:

one or more processors;

computer-readable media; and

one or more program modules stored on the computer-readable media and executable by the one or more processors to cause the computing system to;

provide a web application to a client device via a first network service;

extract from the web application serialized data associated with the web application, the serialized data including a plurality of layers of the web application;

remove first linkage data from the serialized data to produce a data package, the first linkage data linking at least some of the plurality of layers of the web application; and

transmit the data package to a second network service, the data package configured to have second linkage data of the second network service appended to it by a constructor component, the second linkage data linking the plurality of layers of the web application together.

2. The computing system of claim 1, wherein the one or more program modules are further executable by the one or more processors to cause the computing system to:

detect termination of the first network service; and

transmit the data package to the second network service responsive to detecting the termination.

3. The computing system of claim 1, wherein the data package includes state information of the web application.

4. The computing system of claim 3, wherein the state information includes first state information corresponding to a first time, and second state information corresponding to a second time, the second time later than the first time.

5. The computing system of claim 1, wherein the one or more program modules are further executable by the one or more processors to:

cause the computing system to determine that the web application is to be migrated from the client device to another device; and

transmit the data package to the second network service responsive to determining that the web application is to be migrated to the other client device.

6. The computing system of claim 1, wherein the serialized data comprises at least an object related to a programming language.

7. The computing system of claim 1, wherein the plurality of layers relate to at least one of a database, a web server, a rendering side, a display, an application layer, a client side logic, or a server side logic.

8. A method, comprising:

transmitting a web application over a network for a client device by a first host service;

generating a data package for the web application, the data package including a plurality of layers of the web application and excluding at least first linkage data that links at least some of the plurality of layers of the web application, the data package configured to accept second linkage data of a second host service appended to it by a constructor component of the second host service, the second linkage data linking the plurality of layers of the web application together; and

transmitting the data package to the second host service as part of a relocation of the web application from the first host service to the second host service.

9. The method of claim 8, the method further comprising detecting a termination of the first host service, and initiating the relocation responsive to at least the detecting.

10. The method of claim 8, wherein the data package further includes run-time state information for the web application.

11. The method of claim 10, wherein the run-time state information includes a rollback state.

12. The method of claim 8 further comprising:

receiving a request to migrate the web application to another client device;

preserving a current run-time state in the data package; and

initiating the relocation of the web application responsive to the request.

13. The method of claim 8 wherein the web application includes serialized data that comprises at least one of an object related to a programming language.

14. The method of claim 8 wherein the plurality of layers relate to at least one of a database, a web server, a rendering side, a display, an application layer, a client side logic, or a server side logic.

15. One or more computer storage devices comprising a plurality of instructions executable by one or more processors of a computing system to cause the computing system to:

host a web application as part of a first network service, the web application including serialized data that comprises at least one programming language object;

responsive to a determination that the web application is to be migrated from the first network service to a second network service, generate a data package for the web application, generating the data package including;

extraction of the serialized data from the web application;

removal of first linkage data from the serialized data, the first linkage data linking at least some of the plurality of layers of the web application; and

preservation of run-time state data of the web application within the data package; and

transmit the data package to the second network service, the data package configured to have second linkage data of the second network service appended to it by a constructor component, the second linkage data linking the plurality of layers of the web application together.

16. The one or more computer storage devices of claim 15, wherein the run-time state data includes one or more of current run-time state data or rollback run-time state data.

17. The one or more computer storage devices of claim 15, wherein the plurality of layers relate to at least one of a database, a web server, a rendering side, a display, an application layer, a client side logic, or a server side logic.

18. The one or more computer storage devices of claim 15, wherein the plurality of instructions are further executable by the one or more processors of the computing system to cause the computing system to initiate migration of the web application to the second network service responsive to a request to migrate the web application from a first client device to a second client device.

19. The one or more computer storage devices of claim 18, wherein the preservation of the run-time state data includes preservation of current run-time state data.

20. The one or more computer storage devices of claim 15, wherein the plurality of instructions are further executable by the one or more processors of the computing system to cause the computing system to identify the second network service as a suitable network service based at least on characteristics of the second network service.
