Answer: Spot Instances
Spot Instances are the most cost-effective option for delay-tolerant and interruptible workloads. Since the batch processing job runs for a few hours every week and can tolerate delays, Spot Instances would be the most cost-effective choice. On-Demand Instances and Reserved Instances are more suitable for long-running or stable workloads, while Dedicated Hosts are designed for strict compliance requirements.
