Starting today, payer accounts can access all of their linked accounts’ Reserved Instance (RI) purchase recommendations from a centralized view, making it easy to identify cost savings opportunities on a per-account basis. Previously, payer accounts were only able to access recommendations based on the aggregate usage across all of their accounts. This launch expands the RI purchase recommendation capabilities to allow payer accounts to generate and view recommendations based on the usage incurred by each account. This allows you to easily identify the cost savings opportunities for each of your accounts from a central location, eliminating the need to access recommendations separately for each of your accounts.

AWS Cost Explorer provides you with Reserved Instance (RI) purchase recommendations based on your Amazon EC2, Amazon RDS, Amazon Redshift, Amazon ElastiCache, and Amazon Elasticsearch usage. To generate these recommendations, AWS Cost Explorer analyzes your usage to automatically identify the usage that can be covered with RIs and generates RI purchase recommendations to optimally cover your on-demand usage at a discounted RI rate—including automatically identifying instance family usage that can be most efficiently covered with Size-Flexible RIs. From there, you can refine your recommendations by adjusting the RI parameters (e.g., return only recommendations for partial upfront convertible RIs with a one-year term) and the historical time period of usage over which your recommendations are calculated (e.g., the last 60 days).

To access your purchase recommendations, go to AWS Cost Explorer. To learn more about RI cost management, please visit the Reserved Instance Reporting webpage or refer to the Getting Reserved Instance Recommendations user guide.
