Stopping, Starting, or Restarting an Instance
You can stop, start, or restart an instance as needed to update software or resolve error conditions.
If the instance is scheduled for infrastructure maintenance, when it is restarted, it is restarted on a healthy physical host.
For steps to manage the lifecycle state of instances in an instance pool, see Stopping and Starting the Instances in an Instance Pool.
For permissions, see Required IAM Policy for Working with Instances.
