A controller is provided for a Cloud based service handling multiple types of traffic in a telecommunications network, the controller comprising: a first stage configured to automatically model use of Cloud resources allocated to the service for specific workloads of each of a plurality of traffic types, so as provide a variety of models for each traffic type; a second stage configured to automatically reduce the number of and generalise the models so as to provide generalised models for each traffic type applicable to other workloads than the specific loadings; a third stage configured to automatically evaluate accuracy of the generalised models for various combinations of given workloads, in each combination each of the given workloads being of a corresponding traffic type, and to select one of the generalised models dependent upon evaluated accuracy; and a fourth stage configured to control operation of the Cloud resources according to the selected model.

A configuration method, equipment, system and computer readable medium for determining a new configuration of calculation resources associated to a function and to at least one future time slot, the calculation resources being defined as different calculation capacities allocated to the function during a time slot and included within at least one computer, the configuration method comprising a first step of determining an old demand, a second step of determining a plurality of conditional probabilities associated to the old demand and to a plurality of new demands, a third step of determining a plurality of reconfiguration costs associated to a plurality available configurations, a step of selecting the new configuration as being the available configuration associated to the minimal reconfiguration cost.

A method, in a virtualized system, for balancing a load across multiple virtual machines instantiated over physical hardware of the system, including vertically scaling the capacity of respective ones of the VMs up to a physical capacity limit, L, from an initially allocated physical capacity, L, by providing access to additional resources of the physical hardware in response to an increased load causing the or each VM to reach or exceed a threshold capacity L, and horizontally scaling the capacity of the system by supplementing the multiple VMs with an additional VM instantiated using a hypervisor of the system when a predefined proportion, U, of the VMs have a capacity L.
