Abstract: A method and device manager for controlling program components in a network device, wherein the network device is used for handling data traffic in a communication network. First, the device manager identifies, out of a set of predefined policies, a policy comprising rules which determine how the network device should operate when handling data traffic. Then, program components required to fulfil the identified policy are identified and existing program components present in the network device are determined. The device manager further pushes any of the required program components being absent in said existing program components, to the network device. Thereby, any network device(s) can be configured and/or upgraded automatically according to appropriate predefined policies, requiring a minimum of manual work. The predefined policies can also easily be modified or extended to deploy new and/or upgraded functions.

Abstract: A method and control node for managing cloud resources in a communications network for a client being served by a primary data center holding service data associated with a cloud service being executed for the client in the primary data center. A first backup data center having free processing and storage resources for the cloud service, is selected based on usage of links between a source node associated with the client and the first backup data center. The service data is then saved in the first backup data center, thereby enabling the cloud service to be recovered in the first backup data center. If the usage of links in potential communication paths between the source node and the first backup data center exceeds a link usage threshold, the saved service data may be transferred from the first backup data center to a second backup data center.
