Which AWS pricing model gives the steepest discount on EC2 in exchange for the workload tolerating interruption with two minutes' notice?
AOn-Demand Instances
BReserved Instances (standard)
CSpot Instances
DDedicated Hosts
Answer & Solution
Correct answer: C. Spot Instances
Spot pricing offers up to ~90% off on-demand but reclaims capacity with 2-min notice — ideal for batch, CI/CD, EMR, stateless web tier. On-demand has no discount. Dedicated Hosts cost more. RIs trade flexibility for commitment.
