In an embodiment, a unit workload comprises an average processor speed and an average memory amount required by execution of images. If an integer multiple of the average processor speed required minus a free processor speed at a source computer is greater than a first threshold amount, an integer multiple of the average memory amount required minus a free memory amount at the source computer is greater than a second threshold amount, the integer multiple of the average processor speed required minus a processor speed requirement of a source image at the source computer is less than a third threshold amount, and the integer multiple of the average memory required minus a memory requirement of the source image at the source computer is less than a fourth threshold amount, then deployment of the source image is moved from the source computer to a destination computer.
