AWS AMI deprecation (API: ec2:RunInstances Not authorized for images)

You are correct indeed. Windows AMI are deprecated when a new version is released (see http://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/Basics_WinAMI.html)

There is no "point and click" solution as of today, documentation says : "AWS updates the AWS Windows AMIs several times a year. Updating involves deprecating the previous AMI and replacing it with a new AMI and AMI ID. To find an AMI after it's been updated, use the name instead of the ID. The basic structure of the AMI name is usually the same, with a new date added to the end. You can use a query or script to search for an AMI by name, confirm that you've found the correct AMI, and then launch your instance."

One possible solution might be to develop a CloudFormation Custom Resource that would check for AMI availability before launching an EC2 instance.

See this documentation about CFN Custom Resources : http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/crpg-walkthrough.html

And this talk from re:Invent : https://www.youtube.com/watch?v=ZhGMaw67Yu0#t=945 (and this sample code for AMI lookup)

You also have the option to create your own custom AMI based on an Amazon provided one.Even if you do not modify anything. Your custom AMI will be an exact copy of the one provided by Amazon but will stay available after Amazon AMI's deprecation.

Netflix has open sourced tools to help to manage AMIs, have a look at Aminator

Linux AMI are deprecated years after release (2003.11 is still available today !) but Windows AMI are deprecated as soon as a patched version is available. This is for security reason.

This ps script works for my purposes, we use windows 2012 base image:

$imageId = "xxxxxxx"

if ( (Get-EC2Image -ImageIds $imageId) -eq $null ) {

    $f1 = New-Object  Amazon.EC2.Model.Filter ; $f1.Name="owner-alias";$f1.Value="amazon"
    $f2 = New-Object  Amazon.EC2.Model.Filter ; $f2.Name="platform";$f2.Value="windows"

    $img = Get-EC2Image -Filters $f1,$f2 | ? {$_.Name.StartsWith("Windows_Server-2012-RTM-English-64Bit-Base")} | Select-Object -First 1

    $imageId =$img.ImageId

}
