How to know the version of the AMI used by a subscriber?

To address your questions about tracking AMI versions and subscriber information in AWS Marketplace:

1. When you add a new version to your existing product in AWS Marketplace, a new Product ID is not generated. The Product ID remains the same for all versions of a product. Each product is assigned a unique product code when it's created, which is used for usage tracking and permissions across all versions.

2. To track subscribers and AMI version information using Data Feeds, you should focus on the following tables:

   • The Customer Subscriber table: This table provides information about subscribers to your product, including their AWS account ID and the product code they've subscribed to.

   • The Product Usage table: This table contains detailed usage information, including the AMI ID used by subscribers. It will show you which version of your product (identified by the AMI ID) each customer is using.

These tables in the Data Feed service will give you the necessary information to track which subscribers are using which versions of your AMI-based product. The AMI ID in the Product Usage table corresponds to the specific version of your product, allowing you to identify which version each subscriber is using.

It's important to note that when you add new versions to your product, you should keep track of which AMI ID corresponds to which version number. This will help you interpret the data from the Product Usage table more effectively.

Remember that while you can add new versions and update version information, you cannot update the AMI for an existing version. If you need to update the AMI itself, you must create a new version.
