EUCSUS05-BP01 Optimize machine image creation, copying, and sharing to each environment (like development, testing, and production) 

Using automation with machine images facilitates scalability and elasticity, minimizing over-provisioning and associated energy consumption. Centralized management and compliance reporting further support sustainability initiatives. Overall, automation pipelines contribute to lower environmental impact and improved resource optimization.

Level of risk exposed if this best practice is not established: Low

Implementation guidance

Use a dedicated and separate account to create your Amazon AppStream images to manage your changes and your image history. Push the image (copy or share) with other development or production AWS accounts. For more detail, see UpdateImagePermissions and UpdateWorkspaceImagePermission.
