Entirely depends on context, like asking how long is a piece of string. One VM could be 200 cores, or it could be 1 core. It could also be a kubernetes/docker worker as-well so one VM may be thousands of containers. Finally they could instead just be important VM's. You could imagine a small or medium company having maybe 4 VM's each for prod, staging, testing etc... letting CDN's handle scaling (with everything else running on local dev machines) and so that 12,000 could be an entire 3,000 companies whole stacks.
