AWS Directory Service provides you with an easy way to seamlessly join your Amazon EC2 for Windows instances to a domain. You can join an instance to an existing, on-premises Active Directory, using AD Connector, or a stand-alone, Simple AD directory running in the AWS Cloud. Using the AWS Management Console or the EC2 API, you can choose which domain a new instance will join when it launches. For existing instances, you can use the EC2 API to seamlessly join them to a domain. To learn more, please see our documentation.

On-Demand Instances let you pay for compute capacity by the hour with no long-term commitments or upfront payments. You can increase or decrease your compute capacity depending on the demands of your application and only pay the specified hourly rate for the instances you use. Amazon EC2 always strives to have enough On-Demand capacity available to meet your needs, but during periods of very high demand, it is possible that you might not be able to launch specific On-Demand instance types in specific Availability Zones for short periods of time.

SQL Server Express Edition, Microsoft IIS and ASP.NET can be used on any Amazon EC2 instance running Windows Server for no additional cost.

Reserved Instances provide you with a capacity reservation, so you can have confidence that you will be able to launch the instances you have reserved when you need them. There are 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.

Reserved Instances can be purchased for 1 or 3 year terms, and the one-time fee per instance is non-refundable. Reserved Instances are billed for every hour during the entire Reserved Instance term (which means you’re charged the hourly fee regardless of whether any usage has occurred during an hour). Reserved Instances are currently available for Amazon EC2 running Linux/UNIX, SUSE Linux, Microsoft Windows Server, and Microsoft SQL Server. Click here to learn more about Reserved Instances.

If Microsoft chooses to increase the license fees that it charges for Windows or SQL Server, we may correspondingly increase the per-hour usage rate for previously purchased Reserved Instances with Windows or Windows and SQL Server. The initial one-time payment for a Reserved Instance will be unaffected in this situation. Any such changes would be made between Dec 1 – Jan 31, with at least 30 days’ notice. If the per-hour usage price does increase, you may continue to use your Reserved Instance with Windows or Windows and SQL Server with the new per-hour usage price, convert your Reserved Instance to a Reserved Instance with Linux, or request a pro rata refund of the upfront fee you paid for the Reserved Instance with Windows.

For more information, visit the EC2 pricing page

As of December 2nd, 2014, your volume discount is calculated based on the total list value of a Reserved Instance, which includes both the upfront and recurring hourly payments of your Reserved Instances. Customers’ existing volume discount position relative to the tiers will not be affected by this adjustment.

If you purchase a large amount of Reserved Instances in an AWS region, you will automatically receive discounts on your upfront fees and hourly fees for future purchases of Reserved Instances in that AWS region. Reserved Instance Marketplace purchases do not qualify for the volume discount but the prorated remaining list value for these purchases will count towards your volume discount status. Reserved Instance Tiers are determined based on the List Value (non-discounted total price) for the active Reserved Instances you have per AWS region.
