A public-safety CAD reporting fleet runs 24/7 on the same instance family for the next one to three years with predictable utilization. Which approach typically lowers cost versus pure On-Demand?
Select an answer to reveal the explanation.
Short Explanation
When the lights never turn off on those CAD boxes, AWS will cut the bill if you commit — Reserved Instances or Savings Plans are the multi-year discount handshake. Spot can vanish mid-shift, pure On-Demand leaves money on the table, and a Capacity Reservation alone is about holding space, not the same as the commitment discount story.
Full Explanation
Reserved Instances and Savings Plans reduce compute cost when you commit to a consistent usage or spend pattern over one or three years. Steady 24/7 municipal reporting workloads are classic commitment candidates. Spot pricing assumes interruption tolerance, remaining On-Demand forever forgoes the discount, and Capacity Reservations primarily guarantee capacity availability rather than replacing commitment discount semantics.
