METHODS AND SYSTEMS FOR CREATING AND APPLYING PATCHES FOR VIRTUALIZED APPLICATIONS

A method may include identifying a first version of a virtualized application. The first version of the virtualized application may include a first read-only virtualization sublayer, and the first read-only virtualization sublayer may provide a base state of the first version of the virtualized application. The method may also include identifying a second version of the virtualized application. The second version of the virtualized application may include a second read-only virtualization sublayer, which may provide a base state of the second version of the virtualized application. The method may further include determining a difference between the first read-only virtualization sublayer and the second read-only virtualization sublayer and using the difference to create a patch configured to update an instance of the first version of the virtualized application to an instance of the second version of the virtualized application. Various other methods, systems, and computer-readable media are also disclosed.
