A city 911 voice path must stay up without interruption during an outage drill. Why is Amazon EC2 Spot the wrong purchase option for that path?
Select an answer to reveal the explanation.
Short Explanation
Picture a 911 line that cannot drop mid-call. Spot is interruptible spare capacity AWS can reclaim. Keep must-not-stop paths on On-Demand, Reserved, or Savings Plans instead.
Full Explanation
Spot Instances offer steep discounts on unused EC2 capacity but can be interrupted when AWS needs the capacity back. Non-interruptible civic workloads such as emergency voice paths should use On-Demand, Reserved Instances, Savings Plans, or other committed options. Spot is appropriate for flexible batch or stateless work, not for always-on critical paths. Cost myths and on-premises-only claims are incorrect.
