Problem
When creating a new CIS Hardened Image in AWS or switching Instance Types for an existing HI VM, the following message is displayed:
“Failed to create / modify instance type - The instance configuration for this AWS Marketplace product is not supported“
Solution
AWS frequently adds new Instance Types to their available lineup, which may include processor architecture and other hardware changes that require review and approval by the developers offering products on AWS Marketplace. These new instances are opt-in and have to be verified & marked as compatible by the vendor.
Between February 21st and May 1st 2025, CIS will not be able to implement requests for new instance types on AWS. After this window, we will modify the requested images to add the new instance types as long as that instance type family is available for that image. This pause is related to the 2025 CIS Hardened Images on Amazon Web Services (AWS) Price Change and associated maintenance operations.
A list of currently compatible Instance Types can be viewed by navigating to the CIS Hardened Image page on AWS Marketplace and selecting the “Pricing” tab. The supported EC2 Instance Types are displayed in the pricing list along with their cost.
Shown below is an example of the “CIS Amazon Linux 2 Kernel 4.14 Benchmark - Level 1“ offering.
