The billing of the instance continues after the instance is stopped, and resources are retained for the instance. StopCharging: The instance is stopped in economical mode. The billing of some resources of the instance stops after the instance is stopped. When the instance is stopped, its resources such as vCPUs, memory, and public IP address are released. The instance may be unable to start again if some required resources are out of stock in the current region. Not-applicable: The instance does not support economical mode.	KeepCharging
