Explanation

For a short-term, uninterrupted workload like running tests for 1 month, On-Demand Instances are the most cost-effective option. They provide flexibility without requiring long-term commitments or upfront payments. Other options like Spot Instances may be cheaper but are unsuitable for uninterrupted workloads because they can be terminated by AWS if the capacity is required elsewhere. Reserved Instances and Compute Savings Plans require longer commitments and are not ideal for a single-month use case.
