After purchasing Savings Plans, the company wants email alerts when daily Savings Plans utilization falls below 90%. Which of the following will achieve this?

AWS Budgets is the most appropriate service for monitoring Savings Plans utilization and sending alerts. It allows you to create custom budgets based on cost or usage, including specific Savings Plans metrics. You can configure a budget to monitor daily Savings Plans utilization and set a threshold (e.g., 90%). When the actual utilization falls below this threshold, AWS Budgets can publish a notification to an Amazon SNS topic, which can then send email alerts. Incorrect options: CloudWatch alarms can monitor metrics, but the Savings Plan check in AWS Trusted Advisor is a recommendation, not a real-time metric suitable for continuous alarming on utilization. Using an SQS queue directly for email alerts is also not the standard or most efficient method; SNS is designed for fan-out messaging, including email. While CloudWatch alarms can monitor the SavingsPlansUtilization metric, AWS Budgets offers a more direct and integrated solution for financial and usage alerting, specifically designed for cost management and optimization. "Savings Plans alert" is not a native AWS service or feature. While you can create alerts about Savings Plans, there isn't a dedicated "Savings Plans alert" service.
