Abstract: There is provided a method of training a model for use with a software installation process. A software installation process is run a plurality of times (102). Each time the software installation process is run, one parameter in a set of parameters with which the software installation process is rum is changed to generate a respective software installation process output (104). Each software installation process output is used with its respective set of parameters to train a model (106). The model is trained to identify one or more parameters that are a cause of a failed software installation process based on the output of the failed software installation process.

Abstract: A method and a cloud management node for enabling usage of a virtual machine in a distributed cloud of resources for processing and storing of data. When receiving a VM image from a client with a set of files of an operating system for running the virtual machine, the cloud management node distributes the VM image to a plurality of local data centers forming the distributed cloud. In return, the cloud management node receives local identifications of the VM image from the local data centers, and creates a mapping between the received local identifications and a global identification of the VM image. The global identification is then returned to the client, thereby enabling the client to change the VM image in the local data centers by referring to the global identification in communication with the cloud management node.

Abstract: Methods and nodes (200, 202) in a data distribution network, for distributing content to multiple consuming nodes (C1, C2, C3, . . . ). A first node (200) detects (2:2) multiple data flows (2:1b) of a first content from the first node to a second node (202) in the distribution network, when the first node operates as delivering node of the first content for the consuming nodes. The first node then instructs (2:4) the second node to operate as delivering node of the first content for the consuming nodes and redirects (2:5) the consuming nodes to use the second node as delivering node of the first content. The first node further reduces (2:6) the multiple data flows to a common data flow of the first content to the second node. Thereby, efficiency can be improved in the data distribution network by reducing the number of data flows between the first and second nodes.
