- jameshart 3y agoFlux is a quantity of ‘something’ per unit time per unit ‘area’. The value of flux measurements is to be comparable across different scales. When looking at scaling software systems the equivalent is looking at ‘requests per second per process’, which is sort of a flux metric. One way to think of auto scaling is as a process that adjusts the number of processes to keep constant request flux as the overall request volume changes.

"By the end of that summer of 1983, Richard had completed his analysis of the behavior of the router, and much to our surprise and amusement, he presented his answer in the form of a set of partial differential equations."
