The spot share
Spot is 63.6% cheaper than on-demand, and it can be taken back. How much of the fleet should run on it?
Ten servers run all month. Some sit in the harbour's empty berths on spot, cheap until a paying ship arrives and a whole row is cleared at once. On-demand spares cover one reclaim. The panels show the bill before spares, the servers one reclaim takes, and the total.
Board: EC2 & Security Groups →The three panels stack on a narrow screen; the dials stay above them, and the swept table scrolls sideways.
