Answer: Compute Savings Plans

## Explanation **Compute Savings Plans** is the correct answer because: - **Savings Plans** are AWS pricing models that offer significant discounts (up to 72%) in exchange for a commitment to a consistent amount of usage (measured in $/hour) for a 1- or 3-year term - **Compute Savings Plans** specifically apply to EC2 instance usage, regardless of instance family, size, AZ, region, OS, or tenancy - This provides flexibility while still offering substantial cost savings compared to On-Demand pricing **Why the other options are incorrect:** - **Auto Scaling group**: This is an EC2 feature for automatically scaling capacity up or down based on demand, but it doesn't provide cost savings through commitments - **On-Demand Instance**: This is the standard pay-as-you-go pricing with no commitments and no discounts - **EC2 instance store**: This refers to temporary block-level storage physically attached to the host computer, not a cost-saving mechanism Savings Plans are AWS's recommended way to save on compute costs when you can commit to consistent usage patterns.
