Buy Reserved Instances

To purchase a Reserved Instance, search for Reserved Instance offerings from Amazon and third-party sellers, adjusting your search parameters until you find the exact match that you're looking for.

When you search for Reserved Instances to buy, you receive a quote on the cost of the returned offerings. When you proceed with the purchase, Amazon automatically places a limit price on the purchase price. The total cost of your Reserved Instances won't exceed the amount that you were quoted.

If the price rises or changes for any reason, the purchase is not completed. If, at the time of purchase, there are offerings similar to your choice but at a lower price, Amazon sells you the offerings at the lower price.

Before you confirm your purchase, review the details of the Reserved Instance that you plan to buy, and make sure that all the parameters are accurate. After you purchase a Reserved Instance (either from a third-party seller in the Reserved Instance Marketplace or from Amazon), you cannot cancel your purchase.

Note

To purchase and modify Reserved Instances, ensure that your user has the appropriate permissions, such as the ability to describe Availability Zones. For information, see Example Policies for Working With the Amazon CLI or an Amazon SDK and Example Policies for Working in the Amazon EC2 Console.

Choosing a platform

Amazon EC2 supports the following Linux platforms for Reserved Instances:

  • Linux/UNIX

  • Linux with SQL Server Standard

  • Linux with SQL Server Web

  • Linux with SQL Server Enterprise

  • SUSE Linux

  • Red Hat Enterprise Linux

  • Red Hat Enterprise Linux with HA

When you purchase a Reserved Instance, you must choose an offering for a platform that represents the operating system for your instance.

  • For SUSE Linux and RHEL distributions, you must choose offerings for those specific platforms, i.e., for the SUSE Linux or Red Hat Enterprise Linux platforms.

  • For all other Linux distributions (including Ubuntu), choose an offering for the Linux/UNIX platform.

  • If you bring your existing RHEL subscription, you must choose an offering for the Linux/UNIX platform, not an offering for the Red Hat Enterprise Linux platform.

Important

If you plan to purchase a Reserved Instance to apply to an On-Demand Instance that was launched from an Amazon Web Services Marketplace AMI, first check the PlatformDetails field of the AMI. The PlatformDetails field indicates which Reserved Instance to purchase. The platform details of the AMI must match the platform of the Reserved Instance, otherwise the Reserved Instance will not be applied to the On-Demand Instance. For information about how to view the platform details of the AMI, see Understand AMI billing information.

For information about the supported platforms for Windows, see Choosing a platform in the Amazon EC2 User Guide for Windows Instances.

Queue your purchase

By default, when you purchase a Reserved Instance, the purchase is made immediately. Alternatively, you can queue your purchases for a future date and time. For example, you can queue a purchase for around the time that an existing Reserved Instance expires. This can help you ensure that you have uninterrupted coverage.

You can queue purchases for regional Reserved Instances, but not zonal Reserved Instances or Reserved Instances from other sellers. You can queue a purchase up to three years in advance. On the scheduled date and time, the purchase is made using the default payment method. After the payment is successful, the billing benefit is applied.

You can view your queued purchases in the Amazon EC2 console. The status of a queued purchase is queued. You can cancel a queued purchase any time before its scheduled time. For details, see Cancel a queued purchase.

Buy Standard Reserved Instances

You can buy Standard Reserved Instances in a specific Availability Zone and get a capacity reservation. Alternatively, you can forego the capacity reservation and purchase a regional Standard Reserved Instance.

To buy a Standard Reserved Instance using the Amazon CLI

  1. Find available Reserved Instances using the describe-reserved-instances-offerings command. Specify standard for the --offering-class parameter to return only Standard Reserved Instances. You can apply additional parameters to narrow your results. For example, if you want to purchase a regional t2.large Reserved Instance with a default tenancy for Linux/UNIX for a 1-year term only:

    aws ec2 describe-reserved-instances-offerings \
    --instance-type t2.large \
    --offering-class standard \
    --product-description "Linux/UNIX" \
    --instance-tenancy default \
    --filters Name=duration,Values=31536000 Name=scope,Values=Region

    To find Reserved Instances on the Reserved Instance Marketplace only, use the marketplace filter and do not specify a duration in the request, as the term might be shorter than a 1– or 3-year term.

    aws ec2 describe-reserved-instances-offerings \
    --instance-type t2.large \
    --offering-class standard \
    --product-description "Linux/UNIX" \
    --instance-tenancy default \
    --filters Name=marketplace,Values=true

    When you find a Reserved Instance that meets your needs, take note of the offering ID. For example:

    "ReservedInstancesOfferingId": "bec624df-a8cc-4aad-a72f-4f8abc34caf2"

  2. Use the purchase-reserved-instances-offering command to buy your Reserved Instance. You must specify the Reserved Instance offering ID you obtained the previous step and you must specify the number of instances for the reservation.

    aws ec2 purchase-reserved-instances-offering \
    --reserved-instances-offering-id bec624df-a8cc-4aad-a72f-4f8abc34caf2 \
    --instance-count 1

    By default, the purchase is completed immediately. Alternatively, to queue the purchase, add the following parameter to the previous call.

    --purchase-time "2020-12-01T00:00:00Z"

  3. Use the describe-reserved-instances command to get the status of your Reserved Instance.

    aws ec2 describe-reserved-instances

Alternatively, use the following Amazon Tools for Windows PowerShell commands:

After the purchase is complete, if you already have a running instance that matches the specifications of the Reserved Instance, the billing benefit is immediately applied. You do not have to restart your instances. If you do not have a suitable running instance, launch an instance and ensure that you match the same criteria that you specified for your Reserved Instance. For more information, see Use your Reserved Instances.

For examples of how Reserved Instances are applied to your running instances, see How Reserved Instances are applied.

Buy from the Reserved Instance Marketplace

You can purchase Reserved Instances from third-party sellers who own Reserved Instances that they no longer need from the Reserved Instance Marketplace. You can do this using the Amazon EC2 console or a command line tool. The process is similar to purchasing Reserved Instances from Amazon. For more information, see Buy Standard Reserved Instances.

There are a few differences between Reserved Instances purchased in the Reserved Instance Marketplace and Reserved Instances purchased directly from Amazon:

  • Term – Reserved Instances that you purchase from third-party sellers have less than a full standard term remaining. Full standard terms from Amazon run for one year or three years.

  • Upfront price – Third-party Reserved Instances can be sold at different upfront prices. The usage or recurring fees remain the same as the fees set when the Reserved Instances were originally purchased from Amazon.

  • Types of Reserved Instances – Only Amazon EC2 Standard Reserved Instances can be purchased from the Reserved Instance Marketplace. Convertible Reserved Instances, Amazon RDS, and Amazon ElastiCache Reserved Instances are not available for purchase on the Reserved Instance Marketplace.

Basic information about you is shared with the seller, for example, your ZIP code and country information.

This information enables sellers to calculate any necessary transaction taxes that they have to remit to the government (such as sales tax or value-added tax) and is provided as a disbursement report. In rare circumstances, Amazon might have to provide the seller with your email address, so that they can contact you regarding questions related to the sale (for example, tax questions).

For similar reasons, Amazon shares the legal entity name of the seller on the buyer's purchase invoice. If you need additional information about the seller for tax or related reasons, contact Amazon Web Services Support.
