Dedicated Hosts can help you address compliance requirements and reduce costs by allowing you to use your existing server-bound software licenses. When you launch instances on a Dedicated Host, the instances run on a physical server that is dedicated for your use. While Dedicated instances also run on dedicated hardware, Dedicated Hosts provide further visibility and control by allowing you to place your instances on a specific, physical server. This enables you to deploy instances using configurations that help address corporate compliance and regulatory requirements. You have the option to launch instances onto a specific Dedicated Host, or you can let Amazon EC2 place the instances automatically. Controlling instance placement allows you to deploy applications to address licensing, corporate compliance, and regulatory requirements. Affinity allows you to specify which Dedicated Host an instance will run on after it has been stopped and restarted.
