A developer lab spins up EC2 instances for a few days of prototype work with no multi-year commitment and unpredictable hours. Which pricing model fits best?
Select an answer to reveal the explanation.
Short Explanation
On-Demand is the pay-as-you-go hotel room — stay a few nights for a prototype, leave when done, no annual lease. Reserved and Savings-style commitments shine when usage is steady and long; Dedicated Hosts are a license/compliance play; Spot is cheaper but can yank the rug.
Full Explanation
On-Demand Instances charge for compute capacity by the second or hour without requiring a reservation or long-term contract, which suits unpredictable short-term development. Reserved capacity commitments reduce cost for steady multi-year usage. Dedicated Hosts address physical-server and licensing needs, and Spot Instances trade price for interruptibility — wrong defaults for fragile short lab work.
