$6m across 2.5 years is like $15.5m, how many engineers man-months to breakeven, I'm pretty sure it was worth the work.

  $6m in perpetuity is like infinite and engineers can be fired.

    It really isn't. The first years dominate the value and later years are worth nothing due to inflation. Google a calculator and use a reasonable discount rate and I suspect you will find that todays value for an infinite perpetuity is a lot less than your intuition might guess. It always surprises me.

      But they will save more than $6M the second year because AWS will up their prices.

      What? It costs me $10M to run something every year, it now costs me $4M to run something every year. I have $6M in my pocket every year now in perpetuity. Compound that annually with the assumption that I maintain or increase top line revenues and thats pure extra profit. Note - I admit, all of this ignores two key things (a) we dont know the engineers salaries who built this and (b) we dont know the ongoing maintenance costs.
