Do they specify the VMs tested? AWS has a lot of different versions of things in play and most of the people I know fall into two camps: fairly generic VMs running compute jobs, which probably would compress well, and VMs running huge databases &#x2F; image farms &#x2F; etc. which do not. By VM count I&#x27;m sure the former dominate but by total storage consumption I think the latter wins – I would, of course, love to see if anyone has hard data.
