This is a marketing opportunity. IBM should contact Google. IBM should suggest a parallel test with returned hardware (z16, z15, z14). Convert their stack to run in a Linux on z image, then duplicate a portion of workload to the z?15? with limited processors and see how they run. Gradually increase the workload until the z has delays the up the number of z processors. Do workload balancing, shifting between images when workload changes, etc, all while documenting workload, power use, costs on newer models, etc.
