The invention discloses a task pushing method and system based on a cloud, and relates to the technical field of communication. The method comprises the steps of pushing a task request to a target terminal according to a pre-configured task pushing list; receiving a performance result fed back by the target terminal after the corresponding task is performed according to the task request; updating the task pushing list according to the performance result fed back by the target terminal; and iteratively performing the task pushing process according to the updated task pushing list until all pushing tasks in the task pushing list are performed completely. According to the method and the system, the performance success rate of the terminal tasks can be improved in a cloud-to-terminal task pushing service mode.
