Repositioning applications from physical devices to the cloud
The disclosure provides for repositioning applications from physical devices to a cloud location without removing the applications from the physical devices. This provides advantages of cloud-based availability for the applications while preserving device configurations. Thus, a user may continue to use the local version during transition to cloud usage so that if a problem arises during transition, adverse effects on user productivity are mitigated. Examples include generating, on a device, a first virtualization layer, and uninstalling an application from the first virtualization layer while capturing uninstallation traffic within the first virtualization layer. Examples further include generating, on the device, a second virtualization layer, installing the application in the second virtualization layer, and generating, from the second virtualization layer with the installed application, an application package. Examples are able to position the application package on a remote node for execution.

generating, on the device, a second virtualization layer, the second virtualization layer including an empty virtual install disk;
installing a copy of the application in the empty virtual install disk included in the second virtualization layer;
generating, from the second virtualization layer with the installed application, an application package; and
transferring the application package to a remote node for execution.

determining a first inventory of applications identified in a list of installed applications maintained by an operating system (OS) of the device;
determining a second inventory of installed applications from a cache of installer files for applications installed on the device;
determining a set of applications that are contained both in the first inventory, and the second inventory, the set consisting of applications having an installer available and installed on the device; and
determining that the application is within the set.
3. The method of claim 2 ,
wherein uninstalling the application from the first virtualization layer comprises:
identifying, for the application, the installer; and
uninstalling the application using the installer for the application; and
wherein installing the application in the second virtualization layer comprises:
installing the application using the installer for the application.
4. The method of claim 1 , further comprising:
preventing the uninstallation traffic from affecting a copy of the application on the device that is not within the first virtualization layer.
5. The method of claim 1 , further comprising:
removing, from the device, the first virtualization layer and the second virtualization layer.
6. The method of claim 1 , further comprising:
prior to transferring the application package to the remote node:
logging into an application resource tool; and
with the application resource tool, executing the application on the device; and
after transferring the application package to the remote node:
logging into the application resource tool; and
with the application resource tool, executing the application on the remote node.
7. The method of claim 1 , further comprising:
prior to executing the application package on the remote node, performing a security scan on the application or the application package; and
based at least on the security scan determining that execution is safe, executing the application package on the remote node.
8. A computer system for repositioning applications from physical devices to a cloud location, the computer system comprising:
a processor; and
a non-transitory computer readable medium having stored thereon program code, the program code causing the processor to:
generate, on a device, a first virtualization layer, the first virtualization layer including a virtual uninstall disk containing a virtual representation of an application;
uninstall the virtual representation of the application from the first virtualization layer while capturing uninstallation traffic within the first virtualization layer;
generate, on the device, a second virtualization layer, the second virtualization layer including an empty virtual install disk;
install a copy of the application in the empty virtual install disk included in the second virtualization layer;
generate, from the second virtualization layer with the installed application, an application package; and
transfer the application package to a remote node for execution.
9. The computer system of claim 8 , wherein the program code is further operative to:
determine a first inventory of applications identified in a list of installed applications maintained by an operating system (OS) of the device;
determine a second inventory of installed applications from a cache of installer files for applications installed on the device;
determine a set of applications that are contained both in the first inventory and second inventory, the set consisting of applications having an installer available and installed on the device; and
determine that the application is within the set.
10. The computer system of claim 9 ,
wherein uninstalling the application from the first virtualization layer comprises:
identifying, for the application, the installer; and
uninstalling the application using the installer for the application; and
wherein installing the application in the second virtualization layer comprises:
installing the application using the installer for the application.
11. The computer system of claim 8 , wherein the program code is further operative to:
prevent the uninstallation traffic from affecting a copy of the application on the device that is not within the first virtualization layer.
12. The computer system of claim 8 , wherein the program code is further operative to:
removing, from the device, the first virtualization layer and the second virtualization layer.
13. The computer system of claim 8 , wherein the program code is further operative to:
prior to transferring the application package to the remote node:
logging into an application resource tool; and
with the application resource tool, executing the application on the device; and
after transferring the application package to the remote node:
logging into the application resource tool; and
with the application resource tool, executing the application on the remote node.
14. The computer system of claim 8 , wherein the program code is further operative to:
prior to executing the application package on the remote node, perform a security scan on the application or the application package; and
based at least on the security scan determining that execution is safe, execute the application package on the remote node.
15. A non-transitory computer readable storage medium having stored thereon program code executable by a first computer system at a first site, the program code embodying a method comprising:
generating, on a device, a first virtualization layer, the first virtualization layer including a virtual uninstall disk containing a virtual representation of an application;
uninstalling the virtual representation of the application from the first virtualization layer while capturing uninstallation traffic within the first virtualization layer;
generating, on the device, a second virtualization layer, the second virtualization layer including an empty virtual install disk;
installing a copy of the application in the empty virtual install disk included in the second virtualization layer;
generating, from the second virtualization layer with the installed application, an application package; and
