I wonder if there's a good way to distinguish different B2B businesses that are more or less effected. For instance, my dad used to be a mechanical engineer designing large construction equipment. Maybe 10% of equipment was replaced a year, so if there was a demand for 10% more equipment one year then they'd have 2x sales. But if there was a 10% decline in demand, then they'd have 0 sales, the broken equipment was acceptable attrition. So... that industry really sucked. But if the businesses have to pay for your services just to keep running, then it won't be too bad. So server sales might go up and down a lot, but AWS demand will be much smoother.
