A cold start costs more than people think.
Spinning up a fresh instance isn't instant. There's a gap between requesting compute and it actually being ready to run your workload, and during that gap, nothing happens.

The advertised price per hour rarely accounts for the minutes spent waiting for the hour actually to start.
