Please note that Reserved Instance prices don't cover storage or I/O costs. Multi-AZ deployments have separate reservation options. Single-AZ DB Reserved Instances can be applied to a database instance in a single Availability Zone. Amazon RDS provides three RI payment options - No Upfront, Partial Upfront, All Upfront - that enable you to balance the amount you pay upfront with your effective hourly price. Amazon RDS Reserved Instances give you the option to reserve a DB instance for a one or three year term and in turn receive a significant discount compared to the On-Demand Instance pricing for the DB instance.
