Which EC2 instance type will meet these requirements?

Explanations:

Spot Instances are a cost-effective choice for running applications that can tolerate interruptions. They allow users to bid on spare EC2 capacity, offering significant savings compared to On-Demand pricing, making them ideal for short-term use.

On-Demand Instances provide flexibility to launch instances as needed without upfront commitment, but they are more expensive than Spot Instances, making them less cost-effective for short, interruptible workloads.

Reserved Instances require a long-term commitment (1 or 3 years) and provide a discount compared to On-Demand pricing, but they are not suitable for short-term use or workloads that can be interrupted, as they involve upfront costs and commitments.

Dedicated Instances run on hardware that is dedicated to a single customer, which may incur higher costs and are not necessary for applications that can be interrupted. They do not offer cost savings for short-term workloads compared to Spot Instances.
