Answer: Reserved instances
When you have instances that will be used continuously and throughout the year, the best option is to buy reserved instances. By buying reserved instances, you are actually allocated an instance for the entire year or the duration you specify with a reduced cost. **Key Points:** - **Reserved Instances** provide significant cost savings (up to 75% compared to On-Demand pricing) for consistent, long-term workloads - **On-Demand Instances** are pay-as-you-go with no long-term commitment, suitable for unpredictable workloads - **Spot Instances** offer the lowest prices but can be interrupted with short notice, suitable for fault-tolerant workloads - **Regular instances** is not a standard AWS pricing term For more on Reserved Instances, please visit: https://aws.amazon.com/ec2/pricing/reserved-instances/
