Methods, apparatuses, and systems for software updates using delta patching are described. A first image representative of a first software stack and a second image representative of a second software stack may be combined into a compound image by a first computer. The first computer may compare the compound image and the first image to determine a difference between the compound image and the first image. The first computer may generate a file representative of the difference between the compound image and the first image, and data representative of the file representative of the difference between the compound image and the first image may be recorded to a computer-readable storage medium.

Software updates using delta patching

Methods, apparatuses, and systems for software updates using delta patching are described. A first computer may compare a first image representative of a plurality of software stacks, and a second image representative of at least one and less than all of the plurality of software stacks to determine a difference between the second image and the first image. The first computer may generate a file representative of the difference between the second image and the first image. The file may include data of instructions for removing each software stack of the plurality of software stacks represented in the first image and not represented in the second image from a second computer. Data representative of the file representative of the difference between the second image and the first image may be recorded to a computer-readable storage medium.
