Measures, including methods, apparatuses and non-transitory computer-readable storage media, associated with network orchestration. A model of a physical resources part of a network and a model of a virtualised resources part of the network are obtained. The physical/virtualised resources part of the network includes a plurality of physical resources/at least one virtualised network function and represents dependencies between different physical/virtualised resources in the physical/virtualised resources part of the network. At least one optimisation operation is performed using the models of the physical and virtualised resources parts of the network to identify an optimised mapping of the at least one virtualised network function onto at least one of the plurality of physical resources. The at least one virtualised network function is instantiated on the at least one of the plurality of physical resources based on the identified optimised mapping.

Network orchestration

Measures, including methods, systems and computer-readable storage mediums, for use in configuring virtual machines on a host device including a plurality of processing cores. A first virtual machine is configured to run on a subset of cores of the plurality. The first virtual machine is of a first type. A second virtual machine is configured to run on any of the cores in the plurality. The second virtual machine is of a second, different type. The first virtual machine is configured to have a first priority which is higher than a second priority of the second virtual machine such that processing resources are available to the first virtual machine when required by the first virtual machine instead of being available to the second virtual machine.
