Amazon EC2 offers Dedicated Hosts, which allow you to access hardware that's fully dedicated for your use. You can use your own licensed software on dedicated infrastructure, even without Software Assurance. For more information on bringing licenses without Software Assurance or License Mobility benefits, please visit this section of the FAQ.
Amazon EC2 Dedicated Host is also integrated with AWS License Manager, a service which helps you manage your software licenses, including Windows Server and SQL Server licenses. In License Manager, you can specify your licensing terms for governing license usage, and easily track licenses for compliance and auditing. You can also specify Dedicated Host management preferences for host allocation and host capacity utilization. Once setup, AWS takes care of these administrative tasks on your behalf, so that you can seamlessly launch virtual machines (instances) on Dedicated Hosts just like you would launch an EC2 instance with AWS-provided licenses.
Use AWS License Manager to start managing your licenses.
