This article provides links to AWS documentation to help you learn and understand the benefits of investments in AWS Reserved Instances (RIs) and/or Savings Plans (SP).
Reserved Instances provide you with significant savings on your Amazon EC2 costs compared to On-Demand Instance pricing. Reserved Instances are not physical instances, but rather a billing discount applied to the use of On-Demand Instances in your account. These On-Demand Instances must match certain attributes, such as instance type and Region, to benefit from the billing discount.
Savings Plans also offer significant savings on your Amazon EC2 costs compared to On-Demand Instance pricing. With Savings Plans, you make a commitment to a consistent usage amount, measured in USD per hour. This provides you with the flexibility to use the instance configurations that best meet your needs and continue to save money, instead of making a commitment to a specific instance configuration. For more information, see the AWS Savings Plans User Guide.
The pricing benefits of Reserved Instances are shared when the purchasing account is billed under a consolidated billing payer account. The instance usage across all member accounts is aggregated in the payer account every month; the normal Reserved Instance logic is applied to calculate the bill.

FYI... RI's on Closed AWS Accounts: If you close your AWS account, the On-Demand billing for your resources stops. However, if you have any Reserved Instances in your account, you will continue to receive a bill for RI's until the term expires. (1 or 3 year terms)
Important: After you purchase a Reserved Instance, you cannot cancel your purchase. However, you might be able to modify, exchange, or sell your Reserved Instance if your needs change.
