Tags enable you to categorize a resource in different ways, such as by purpose, owner, or environment. For example, you might want to tag an activation to identify which servers or virtual machines (VMs) in your on-premises environment you intend to activate. In this case, you could specify the following key-value pairs:</p>  <ul>   <li> <p> <code>Key=OS,Value=Windows</code> </p> </li>   <li> <p> <code>Key=Environment,Value=Production</code> </p> </li>  </ul> <important>   <p>When you install SSM Agent on your on-premises servers and VMs, you specify an activation ID and code. When you specify the activation ID and code, tags assigned to the activation are automatically applied to the on-premises servers or VMs.</p>  </important>  <p>You can't add tags to or delete tags from an existing activation. You can tag your on-premises servers, edge devices, and VMs after they connect to Systems Manager for the first time and are assigned a managed node ID. This means they are listed in the Amazon Web Services Systems Manager console with an ID that is prefixed with "mi-". For information about how to add tags to your managed nodes, see <code>AddTagsToResource</code>. For information about how to remove tags from your managed nodes, see <code>RemoveTagsFromResource</code>.</p><br>
