A company needs to purchase Amazon EC2 instances to support an application that will run continuously for more than 1 year. Which EC2 instance purchasing option meets these requirements MOST…

Dedicated Instances run on hardware dedicated to a single customer for compliance reasons and do not inherently offer the highest cost savings for continuous workloads compared to RIs.

Spot Instances offer significant discounts but are suitable for fault-tolerant workloads that can tolerate interruptions, making them unsuitable for continuous, uninterruptible applications.

Reserved Instances (RIs) offer a significant discount compared to On-Demand prices for EC2 instances when you commit to a consistent amount of compute usage for a 1-year or 3-year term, making them ideal for predictable, long-running workloads.

On-Demand Instances allow users to pay for compute capacity by the hour or second with no long-term commitments, which is the most expensive option for continuously running workloads.
