Spot Instances
Suggested answer: D

Explanation:

Spot Instances are Amazon EC2 instances that are available at a discounted price compared to On-Demand pricing. Spot Instances use spare EC2 capacity that is not being used by other customers, and the price fluctuates based on supply and demand. Customers can request Spot Instances for their applications and specify the maximum price they are willing to pay per hour. If the Spot price is lower than the customer's bid, the Spot Instance is launched and the customer pays the current Spot price. However, if the Spot price rises above the customer's bid, the Spot Instance is terminated by AWS and the customer is charged for the partial hour of usage. Therefore, Spot Instances can provide discounts of up to 90% or more, but they are not suitable for applications that require continuous or predictable availability.Spot Instances are recommended for applications that are flexible, fault-tolerant, or have low priority, such as batch processing, data analysis, or testing and development.
