A company has a predictable, business-critical EC2 compute workload for the next 3 years and wants to minimize costs. Which option best meets these requirements?

Savings Plans offer significant discounts (up to 72%) compared to On-Demand pricing in exchange for a commitment to a consistent amount of compute usage (measured in $/hour) for a 1-year or 3-year term. This aligns perfectly with a predictable, business-critical workload over 3 years, providing the best cost optimization. Spot Instances are unsuitable for business-critical workloads because they can be interrupted with two minutes of notice, leading to potential service disruptions. Dedicated Hosts provide dedicated physical servers but are generally more expensive and not primarily a cost-saving mechanism for compute. On-Demand Instances offer flexibility but are the most expensive option, failing to meet the requirement for cost minimization over a long term.
