Abstract: The present invention discloses a method and a device for handling an exception event in a telecommunication cloud to shorten the notification path and increase the reliability. The method of the present invention includes: detecting a resource state; transmitting a detected resource state exception event to the application layer agent process via a failure notification channel between an infrastructure as a service (IaaS) agent process and an application layer agent process as pre-established inside a host machine Host, and/or transmitting a detected resource state exception event to the application layer management process via a failure notification channel between the IaaS agent process and an application layer management process as pre-established inside the host machine Host. By means of the present invention, the notification path is shortened and the reliability is increased.
