Deregistering managed nodes in a hybrid and multicloud environment

If you no longer want to manage an on-premises server, edge device, or virtual machine (VM) by using Amazon Systems Manager, then you can deregister it. Deregistering a hybrid-activated node removes it from the list of managed nodes in Systems Manager. Amazon Systems Manager Agent (SSM Agent) running on the hybrid-activated node won't be able to refresh its authorization token because it's no longer registered. SSM Agent hibernates and reduce its ping frequency to Systems Manager in the cloud to once per hour.

You can reregister an on-premises server, edge device, or VM again at any time. Systems Manager stores the command history for a deregistered managed node for 30 days.

The following procedure describes how to deregister a hybrid-activated node by using the Systems Manager console. For information about how to do this by using the Amazon Command Line Interface , see deregister-managed-instance.
