Method, management node and processing node are disclosed for continuous availability in a cloud environment. According to an embodiment, the cloud environment comprises a plurality of layers and each layer includes at least two processing nodes. Each processing node in a layer can pull job(s) from the processing nodes in the upper layer if any and prepare job(s) for the processing nodes in the under layer if any. A method implemented at a management node comprises receiving measurement reports from the plurality of layers. The measurement report of each processing node comprises information about job(s) pulled from the upper layer if any and job(s) pulled by the under layer if any. The method further comprises determining information about failure in the cloud environment based on the measurement reports.

Embodiments of the present disclosure relate to a method, a device, and a computer-readable storage medium for allocating system resources among a plurality of network slices in a communication network. In the communication network, a network device determines utility values of two network slices. A network slice corresponds to a set of network functions of a set of services served thereby. A utility value of the network slice indicates the level of demand for system resources by the set of services associated with the network slice. The network device determines a difference between the utility values of the two network slices. If the difference exceeds a threshold utility value, the network device re-allocates system resources among the plurality of network slices in the communication network. According to the embodiments, the communication network updates the system resources allocated for the plurality of network slices only when the difference between the utility values of the two network slices exceeds a certain threshold. Hence, the complexity of updating system resource allocation among the plurality of network slices may be reduced by the method according to the embodiments of the present disclosure.
