Reserved Instance (RI) Purchase Recommendations for your Amazon Redshift, Amazon ElastiCache, and Amazon Elasticsearch Reservations using AWS Cost Explorer
Starting today, you can access custom Reserved Instance (RI) purchase recommendations for your Amazon Redshift, Amazon ElastiCache, and Amazon Elasticsearch reservations via AWS Cost Explorer, in addition to viewing RI purchase recommendations for your Amazon EC2 and Amazon RDS reservations.
To generate these recommendations, Cost Explorer first analyzes your usage to automatically identify all of your on-demand usage that can be covered with RIs for each of the above-mentioned services. From there, Cost Explorer generates RI purchase recommendations to optimally cover your On-Demand usage at a discounted RI rate. To ensure that the recommendations align with your organization’s needs, you can adjust the RI parameters (e.g., return only recommendations for RIs with a one-year term and a partial upfront payment option) and the historical time period of usage on which your recommendations ought to be calculated (e.g., last 60 days). Once you have identified the optimal mix of RIs to address your business needs, you can proceed directly to the individual AWS service console via the links in AWS Cost Explorer.
Please note that you can also programmatically retrieve your recommendations via the AWS Cost Explorer API.
