A batch rendering job can be interrupted and restarted anytime — it's not time-sensitive. Which EC2 purchase option minimizes cost?
A.On-Demand Instances
On-Demand costs the most — no interruption tolerance needed.
B.Spot Instances
Correct. Interruptible + cheapest = Spot.
C.Reserved Instances
Reserved needs 1-3yr commitment for steady-state — wrong fit.
D.Dedicated Hosts
Dedicated Hosts are for per-socket/core licensing, not cheap batch.
Why this answer
Spot Instances use spare capacity at up to ~90% off On-Demand — ideal for fault-tolerant, interruptible workloads. Reserved/On-Demand suit steady or critical loads; Dedicated Hosts are for licensing/compliance.
