Which solution will meet this requirement?
Create an Amazon CloudWatch alarm to monitor the Savings Plan check in AWS Trusted Advisor. Configure an Amazon Simple Queue Service (Amazon SQS) queue for email notification when the utilization drops below 90% for a given day.
Create an Amazon CloudWatch alarm to monitor the SavingsPlansUtilization metric under the AWS/SavingsPlans namespace in CloudWatch. Configure an Amazon Simple Queue Service (Amazon SQS) queue for email notification when the utilization drops below 90% for a given day.
Create a Savings Plans alert to monitor the daily utilization of the Savings Plans. Configure an Amazon Simple Notification Service (Amazon SNS) topic for email notification when the utilization drops below 90% for a given day.
Use AWS Budgets to create a Savings Plans budget to track the daily utilization of the Savings Plans. Configure an Amazon Simple Notification Service (Amazon SNS) topic for email notification when the utilization drops below 90% for a given day.
Explanations:
CloudWatch alarms do not monitor Savings Plan utilization via AWS Trusted Advisor. Trusted Advisor does not track Savings Plans in a way that would trigger alarms.
Although CloudWatch can monitor Savings Plans utilization, an SQS queue is not the best option for email notifications. SNS is the recommended service for this.
Savings Plans alerts are not directly available for setting up custom notifications. CloudWatch or AWS Budgets are the correct services to monitor utilization.
AWS Budgets can track daily utilization of Savings Plans and provide email notifications via SNS, making this the most suitable solution.
