• I think C should be the right answer - On-Demand Instances provide capacity on a pay-as-you-go basis with no upfront commitment. They are suitable for short-term, variable workloads, offering flexibility without the need for long-term commitments. In this scenario, On-Demand Instances would be a cost-effective option for the 2-month duration while avoiding downtime.

• 正解だと思う選択肢: B

  A. Reserved Instances: Involve a commitment to a specific instance type in a particular region for a term of 1 or 3 years. They offer cost savings compared to On-Demand pricing, but may not be suitable for stateless and fault-tolerant workloads with short durations.

  B. Spot Instances: Allow users to bid for unused EC2 capacity, potentially providing cost savings. They are suitable for workloads that are fault-tolerant and can handle interruptions. Spot Instances are a good fit for the described scenario of thousands of simultaneous simulations.

  C. On-Demand Instances: Are charged at the regular, non-reserved pricing. They provide flexibility without any upfront commitments, but may not be the most cost-effective option.

  D. Dedicated Instances: Run on hardware dedicated to a single customer but do not provide significant cost optimization. They are more suitable for scenarios where regulatory or compliance requirements necessitate dedicated hardware.
