||Amazon EC2 now integrates with DevPay, allowing developers to charge users a fee for the use of their AMIs or to provide support for instances.
For more information, refer to the Amazon EC2 Developer Guide.
|Instance type metadata not available in older AMIs.||
The instance-type is only available as part of the instance metadata on instances that expose version 2007-09-28 of the instance metadata. Large and extra large instance types support this version. Small instances types (the original instance type) may not support this version yet, in which case the instance type of m1.small can be assumed. You can query supported versions using the following URL: http://169.254.169.254/.
|Instance limit||New users are limited to a maximum of 20 concurrent instances. If you need a higher limit, contact firstname.lastname@example.org.|
|Creation of Paid AMIs is limited||We are currently accepting only a limited number of partners who will be able to create Paid AMIs. Users interested in selling their Amazon EC2 AMIs through this program should send an e-mail to email@example.com. Please include your name, AWS account ID, company name, and a detailed description of your AMI.|
|Access to public NAT addresses from within EC2||EC2 instances cannot access instances in the new NAT environment through their public IP addresses; they must access the instances through their private IP addresses. The EC2 DNS servers will return the internal IP address when asked about an instance's public DNS name. In this way, DNS lookups that would resolve to a public EC2 IP address will be translated to the correct internal IP address. This only works when using the EC2 DNS servers from an EC2 instance.|
|Console output||Some instances in the direct-addressing environment report a soft lockup error in the console output during boot. This is a false error that does not impact the successful booting of an instance.|
|Console output availability||There were some reports of full console output not being available. Full console output is only guaranteed for instances that were rebooted after this feature was released.|
|AMIs may launch if its Amazon S3 bundle was deleted.||You may be able to launch an AMI after its bundle was altered or deleted from Amazon S3. We discourage deleting an AMI from Amazon S3 without also deregistering the AMI.|
|ec2-delete-bundle Misleading Error Message||The ec2-delete-bundle operation currently returns an error when it attempts to delete an Amazon S3 bucket that is not empty. Despite this error, the files within this bundle are successfully deleted.|
