The new ColdFusion 11 AMIs for Windows and Linux are now available on AWS Marketplace for purchase.
We now have support for not only the existing instances supported for ColdFusion 10 AMI (m1.large and m1.xlarge), but also all the Amazon EC2 insances for M3, C3 and R3. There is also 31 day trial for both the AMIs. You may also chose to pay a discounted annual price for the AMI.
Here is the link on adobe.com for the new ColdFusion 11 Amazon offering.
