In non-limiting examples of the present disclosure, systems, methods and devices for selectively virtualizing software application functions are presented. An application package for a containerized software application may be received. The application package may comprise an application manifest and a virtualization exclusion for a first location of a global file system of the computing device. The containerized software application may be installed in a container comprising a virtual file system. An indication to write a first new file at the first location may be received by the containerized software application. A determination may be made that the first location comprises the virtualization exclusion. The first new file may be written to the first location of the global file system based on the determination that the first location comprises the virtualization exclusion.

Flexible virtualization of application data for specified system locations

In one embodiment, a computer system stores entries for one or more instances of an application with keys generated for the instances in storage. The instances of the application are instantiated on the computer system. The computer system receives a request from the application with a current key for a current instance and parses the storage to determine if the current key is stored in the keys associated with the application. The computer system returns a response to the application with an indication whether the current key is stored as an entry in the one or more entries. The application uses the response to determine a redirection action to one of the one or more instances of the application when the current key is associated with an instance other than the current instance.
