A company has a temporary, variable workload running on EC2 that must complete short bursts of work without being interrupted. Which EC2 purchase option meets this requirement?

On-Demand Instances are the correct choice because they provide compute capacity without any long-term commitment, and you pay only for the compute time you use. This flexibility is ideal for temporary, variable workloads that need to complete short bursts of work without interruption. Spot Instances are incorrect because, while cost-effective, they can be interrupted by AWS with only a two-minute warning when capacity is needed elsewhere. This makes them unsuitable for workloads that must complete without interruption. Savings Plans and Reserved Instances are incorrect because they are designed for steady-state, predictable workloads and require a commitment (1 or 3 years) for a discounted rate, which doesn't align with the "temporary, variable" nature of the described workload.
