#1 is the reason why the math works out in favor of 3 year reservations. I took this into account already: $price = $reservationCost+$hourlyRate*24*365*$numberOfYears Where reservation cost, hourly rate, and number of years are pulled off the chart for 1 or 3 year reservations for whatever instance size you're interested in. #2 is sort of what we're solving for... how much of a yearly price reduction would be necessary to make 3 consecutive 1-year reservations cheaper than a single 3-year reservation (or how much of a 3-year reservation you could effectively abandon and still come out ahead). By my math above, I came up with the magic number being about 40% discount per year making 3x 1-year reservations cheaper than a single 3-year reservation. $765 + $765*x + $765*x^2 = $1515 x = 0.60923 #3 I've yet to use the marketplace, but yes even after discounts happen down the road, your leftover reservation time is certainly worth something, pushing the balance even further in support of 3 year reservations.
