How can AWS customers track and avoid over-spending on underutilized reserved instances?
- Customers can add all AWS accounts to an AWS Organization, enable Consolidated Billing, and turn off Reserved Instance sharing.
- Customers can use Amazon Neptune to track and analyze their usage patterns, detect underutilized reserved instances, and then sell them on the Amazon EC2 Reserved Instance Marketplace.
- Customers can use the AWS Budgets service to track the reserved instances usage and set up alert notifications when their utilization drops below the threshold that they define.
- Customers can use Amazon CloudTrail to automatically check for unused reservations and get recommendations to reduce their bill.
