identifying, in response to receipt of a request to prepare updates between disk images of different computing environments running on computing devices, a common disk image, the common disk image being a disk image common between previous versions of the disk images of the different computing environments running on computing devices;
determining a binary file of differences between a disk image of a first of the computing devices and the identified common disk image;
attaching, using a second of the computing devices, the common disk image and the binary file of differences to an appliance executable on the second of the computing devices; and
creating, using the second of the computing devices, an updated disk image by applying, using the appliance and the binary file of differences, differences to the identified common disk image.
