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

These recommendation analyze all incurred usage eligible to be covered by an RI (e.g. On-Demand usage) and using 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 instance type.

For example, if a resource (such as a cluster) consists of multiple instances with partial coverage, the system may produce more than one recommendation, each reflecting different commitment options (e.g., various term lengths and upfront payment models).

• Num Of Days, default 21 days.
• Preferred Plan, default standard 1 year no upfront.
