Abstract

The dependencies of an application are identified by intercepting application programming interface calls made by an application. A determination is then made at the runtime of the application as to whether the dependencies of the application are present. If the dependencies are not present, a client device upon which the application is executing is configured such that the dependencies are present and are made available only to the authorized application. If the dependencies are present and the application is authorized to interact with the dependencies, the application is permitted to execute.

Claims

1. A computer-implemented method comprising performing computer-implemented operations for:

receiving a request to deploy an application at a client device;

determining whether each of one or more dependencies requisite for deploying the application is present at the client device; and

upon determining that each of the one or more dependencies requisite for deploying the application is not present, configuring the client device such that the dependencies are present.

2. The computer-implemented method of claim 1, further comprising upon determining that each of the one or more dependencies requisite for deploying the application are present, deploying the application at the client device.

3. The computer-implemented method of claim 2, further comprising:

upon deploying the application at the client device, intercepting an application programming interface (API) call from the application, the API call requesting access to a resource;

selecting a copy of the resource to which the API call is to be redirected;

protecting the private location with an access control list (ACL) associated with the resource; and

redirecting the API call to the resource stored at the private location.

4. The computer-implemented method of claim 1, further comprising prior to deploying the application:

installing the application on a monitoring station;

monitoring changes made to the monitoring station during the installation of the application to identify the dependencies; and

storing data identifying the dependencies in a dependency analysis database.

5. The computer-implemented method of claim 4, further comprising prior to deploying the virtualized application:

executing the virtualized application on the monitoring station;

monitoring changes made to the monitoring station during the execution of the virtualized application to identify the dependencies; and

storing data identifying the dependencies in the dependency analysis database,

6. The computer-implemented method of claim 5, wherein monitoring changes made to the monitoring station during the execution of the application comprises:

intercepting API calls made by the application during execution; and

inspecting parameters contained in the API calls to identify the dependencies.

7. The computer-implemented method of claim 6, further comprising:

determining whether each of the one or more dependencies is added or configured during the installation or deployment of the application;

upon determining that each of the one or more dependencies is added or configured during the installation or deployment of the application, storing data indicating that the one or more dependencies that is added or configured during the installation or deployment of the application will need to be present at a runtime of the application.

8. The computer-implemented method of claim 7, wherein determining whether each of the one or more dependencies is added or configured during the installation or deployment of the application comprises querying a registry provided by the operating system.

9. The computer-implemented method of claim 7, wherein determining whether each of the one or more dependencies is added or configured during the installation or deployment of the application comprises querying an internal mapping table that matches API calls to dependencies.

10. A computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by a computer, cause the computer

receive a request to deploy a virtualized application;

determine whether each of one or more dependencies required to deploy the virtualized application is present; and

upon determining that each of the one or more dependencies is not present, configuring a client device upon which the virtualized application is executing such that the dependencies are present.

11. The computer-readable storage medium of claim 10, having further computer-executable instructions stored thereon which, when executed by the computer, cause the computer to deploy the virtualized application at the client device in response to determining that each of the one or more dependencies requisite for deploying the virtualized application are present.

12. The computer-readable storage medium of claim 11, having further computer-executable instructions stored thereon which, when executed by the computer, cause the computer to:

upon deploying the virtualized application on the client device, intercept an application programming interface (API) call from the virtualized application, the API call requesting access to a resource;

selecting a copy of the resource to which the API call is to be redirected;

protecting the private location with an access control list (ACL) associated with the resource; and

redirecting the API call to the resource stored at the private location.

13. The computer-readable storage medium of claim 10, having further computer-executable instructions stored thereon which, when executed by the computer, cause the computer to:

install the virtualized application on a monitoring station;

monitor changes made to the monitoring station during the installation of the virtualized application to identify the dependencies; and

package data identifying the dependencies in an application package configured to be streamed to the client device.

14. The computer-readable storage medium of claim 13, having further computer-executable instructions stored thereon which, when executed by the computer, cause the computer to:

execute the virtualized application installed on the monitoring station;

monitor changes made to the monitoring station during the execution of the virtualized application to identify the dependencies; and

package data identifying the dependencies in the application package configured to be streamed to the client device.

15. The computer-readable storage medium of claim 14, wherein monitoring changes made to the monitoring station during the execution of the virtualized application to identify the dependencies comprises:

intercepting API calls made by the virtualized application during execution; and

inspecting parameters contained in the API calls to identify the dependencies.

16. The computer-readable storage medium of claim 15, having further computer-executable instructions stored thereon which, when executed by the computer, cause the computer to:

determine whether each of the one or more dependencies is added or configured during the installation or deployment of the application;
