Cloud services probably upended this.<p>If my server farm is idle any significant amount, I&#x27;m going to take those servers offline.  If I need capacity, I&#x27;ll spin up some cloud instances in the short term, and I&#x27;ll bring my own servers online until I&#x27;m at an appropriate idle&#x2F;busy metric.<p>I suspect that the days of 99% idle servers are long gone.  I suspect that utilization is probably above 70%.
