After reading this about Azure we now come onto AWS! Microsoft License Mobility – Amazon Web Services (AWS)
Microsoft license terms do not permit you to bring your own license (BYOL) based on your selection. Costs for Windows Server will be calculated as AWS License included running on shared tenancy. The on-premises Windows Server license purchased on or after October 1, 2019 can’t be utilized in AWS. Learn more
Amazon EC2 instances created from AWS AMIs can only leverage the AWS Default License Included purchasing option. However, instances that have been created from AMIs based on your own install media can leverage either the License Included or BYOL purchasing options. As a result, you may want to consider using imported AMIs for instances that are not currently leveraging BYOL, but may be candidates for BYOL in the future.
