Abstract
An embodiment of the present invention is directed to a system for distributing an application environment to a compute node. The system includes a first storage unit for storing blocks of a root image of the compute node and a second storage unit for storing a leaf image comprising new data blocks and changes to the blocks of the root image. The system further includes a union block device for interfacing between the compute node and the first and second storage units to distribute the application environment to the compute node. The union block device creates the application environment by merging the blocks of the root image stored on the first storage unit with the leaf image stored on the second storage unit.
