A company uses Amazon EC2, AWS Fargate, and AWS Lambda to run workloads in its AWS account. The company wants to fully utilize its Compute Savings Plans and receive notifications when Compute Savings Plans coverage drops. Which solution meets these requirements with the MOST operational efficiency?

The correct answer is to create a daily budget for Savings Plans using AWS Budgets and configure it with a coverage threshold to send notifications. AWS Budgets is specifically designed to track and alert on cost and usage, including Savings Plans coverage. Setting a coverage threshold directly addresses the requirement to be notified when coverage drops, ensuring full utilization with minimal operational overhead. Incorrect options: Creating a Lambda function to run a coverage report is less operationally efficient. It requires developing and maintaining custom code, which is more complex than using AWS Budgets' built-in functionality. Creating an AWS Budgets report for the Savings Plans budget, without configuring a coverage threshold, will provide a report but won't automatically send notifications when coverage drops below a desired level. "Savings Plans alert subscription" is not a standard AWS service or feature for monitoring coverage thresholds. While Savings Plans have some notification capabilities, AWS Budgets provides the granular control and alerting needed for coverage.
