This recommendation recommend on RI purchase and is based on customer's historical usage.

These recommendations analyze all incurred usage eligible to be covered by an RI (e.g., On-Demand usage) and use our unique algorithms to simulate possible combinations of RI’s that would cover that usage.

Recommendations are generated at the resource level, rather than by node instance type.

For example, if an OpenSearch domain includes multiple nodes with partial RI coverage, multiple recommendations may be created, each reflecting different commitment terms and upfront payment options.
