|Spot Instances||On December 14, 2009, Amazon EC2 announced the release of Spot Instances. For more information, go to the Amazon EC2 product page.
How does this affect your paid AMIs?
Your existing paid AMIs will continue to work with On-Demand Instances. However, Spot Instances cannot be launched with a paid AMI. If you or your customers make a Spot Instance request for a paid AMI, Amazon EC2 returns an error.
|Failure of Sign-Up Payment||If your product has a sign-up/monthly fee, and the customer's sign-up payment fails because the payment method isn't valid, the customer is not officially subscribed to your product. This can be verified with VerifyProductSubscriptionByTokens (for desktop products) or VerifyProductSubscriptionByPid (for hosted products), which returns a value of "false". The customer can't use the product, even if you've activated the customer. We recommend your product poll the customer's subscription status after activating the customer. If the status is still "false" 15 minutes after activation, then the product should display a special message when the customer tries to use the product the first time. The message should tell the customer to:

|Limitation on AWS services used||You can build an application that monetizes Amazon EC2 or Amazon Simple Storage Service, but not both.|
|Throttling of License Service requests per developer||Requests to the License Service are throttled as necessary. They are throttled per developer instead of per DevPay product. Therefore, if you have multiple DevPay products, the sum of the requests from all your DevPay products is used to determine whether your requests need to be throttled.|
|Information not available on the first of the month||If you visit your DevPay Activity page on the first of the month, your revenue statement for the previous month might not yet be available. We instead recommend that you view the page after you've received the e-mail from AWS that indicates the revenue statement is available. |
Also, the page might display zeros for all the values because the page has not yet been updated with the information for the first day of the month. If this happens, we recommend that you return to the page on the second day of the month.
|Withdrawal limit||When you withdraw money from your Amazon Payments account, the withdrawal amount must be at least $10.00.|
