AWS Cost Explorer allows you to visualize and monitor your reservations both at a high level (e.g., cost savings associated with all Amazon EC2 reservations) or for highly-specific requests (e.g., reservation utilization associated with all regional Amazon EC2 reservations owned by a particular linked account). Starting today, you can access information about the normalized units associated with your reservations in AWS Cost Explorer, making it easier to understand how your reservations (including Size Flexible RIs ) are applied to your instance usage.
