A city recreation registration API sees heavy weekday traffic but almost none on weekends, yet the same peak capacity stays running Saturday and Sunday. What scaling approach best cuts idle cost?
Select an answer to reveal the explanation.
Short Explanation
Leaving weekday rush-hour buses running empty on Sunday still burns fuel. Scale in when demand drops so you are not paying peak rates for quiet hours.
Full Explanation
Elastic scale-in reduces running capacity when metrics or schedules show sustained low demand, which is a primary cost-optimization lever for predictable quiet periods such as weekends. Keeping peak fleets online 24/7 wastes spend. Raising maxima or forcing always-on reserved hosts increases cost rather than aligning capacity with load.
