To manage DB instances billed at the Reserved Instance rate, you can purchase and apply Reserved Instances (RIs) for your specific database engine, instance family, region, and tenancy. RIs offer a significant discount compared to On-Demand instances. You can then associate the purchased RIs with eligible DB instances to start benefiting from the cost savings. AWS provides tools such as the RI Purchase Recommender to help you optimize your RI usage.
