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.
