You may designate database instances as Reserved Instances by calling the Purchasing API or selecting the Reserved Instance option in the AWS console.
You purchase a Reserved Instance for each database instance you plan to use. You will be billed for each hour of the term regardless of whether any usage has occurred. You commit to the entire duration of the Reserved Instance term and pay a discounted hourly rate as shown in the following table.Īlthough these rates apply to Aurora Standard, when using Reserved Instances with Aurora I/O-Optimized, Aurora automatically accounts for the price difference between these options for your usage. To fully utilize the benefits of your RI discounts with Aurora I/O-Optimized, you can purchase 30% additional RIs similar to your current RIs. See pricing example for more information. Your Reserved Instances discounted rate is automatically applied to usage of any size in the same instance family (such as T3 and R5) across Aurora Standard and Aurora I/O-Optimized configurations. Reserved Instances provide flexibility across instance sizes and cluster configuration options. 1-year Reserved Instances provide discounts up to 45% and 3-year Reserved Instances provide discounts of up to 66% over On-Demand Instances.
