@Generated(value="jsii-pacmak/1.120.0 (build 192dc88)", date="2025-12-05T22:26:34.760Z") @Stability(Stable) public class CfnHost extends CfnResource implements IInspectable, IHostRef, ITaggableV2
Allocates a fully dedicated physical server for launching EC2 instances.

Because the host is fully dedicated for your use, it can help you address compliance requirements and reduce costs by allowing you to use your existing server-bound software licenses. For more information, see Dedicated Hosts in the Amazon EC2 User Guide .

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.ec2.*;
 CfnHost cfnHost = CfnHost.Builder.create(this, "MyCfnHost")
