Amazon EC2 Spot Instances let you take advantage of unused EC2 capacity in the AWS cloud. Spot Instances are available at up to a 90% discount compared to On-Demand prices. You can use Spot Instances for various stateless, fault-tolerant, or flexible applications such as big data, containerized workloads, CI/CD, web servers, high-performance computing (HPC), and test & development workloads. Because Spot Instances are tightly integrated with AWS services such as Auto Scaling, EMR, ECS, CloudFormation, Data Pipeline and AWS Batch, you can choose how to launch and maintain your applications running on Spot Instances.

Selected Answer: B

The best Amazon EC2 pricing model for the given requirements of a stateless application workload with occasional downtime and parallel computations would be Spot Instances. Spot instances can be used for workloads that can tolerate interruptions since they offer the lowest cost compared to On-Demand and Reserved Instances. Spot Instances allow users to bid on unused EC2 instances, and the pricing for Spot Instances is based on supply and demand. When the bid price is higher than the current Spot price, the instance will run until the Spot price exceeds the bid price. If the bid price is lower than the current Spot price, the instance is terminated. Therefore, if the company has a stateless application workload that can sustain occasional downtime, it can use Spot Instances to perform massively parallel computations and minimize costs.
