Answer: Savings Plans

Savings Plans provide significant discounts on AWS service costs in exchange for a commitment to a consistent amount of usage (measured in $/hour) for a 1- or 3-year term. **Key points about Savings Plans:** - **Discount mechanism**: You commit to a specific spending amount per hour for 1 or 3 years - **Flexibility**: Unlike Reserved Instances, Savings Plans apply to various AWS services including EC2, Fargate, Lambda, and more - **Cost savings**: Typically offer up to 72% savings compared to On-Demand pricing - **Usage commitment**: You're committing to spend a certain amount per hour, regardless of actual usage **Why other options are incorrect:** - **Amazon Detective**: A security service for analyzing security findings, not related to cost optimization - **AWS Pricing Calculator**: A tool for estimating AWS costs, but doesn't provide actual discounts - **Basic Support**: Included with AWS account, provides limited support but no cost discounts Savings Plans are AWS's flexible pricing model that helps organizations save money while maintaining flexibility in their cloud usage patterns.
