METHOD AND CLOUD MANAGEMENT NODE FOR MANAGING A DATA PROCESSING TASK

A method and a cloud management node for managing a data processing task requested from a client. An amount of energy needed for executing the data processing task is first estimated and a time period during which the data processing task should be executed is also determined. An energy cost during the determined time period is further obtained. The execution of the data processing task is then scheduled within the determined time period based on the estimated amount of needed energy and the obtained energy cost. This scheduling may thus be done so that the energy cost will be as low as possible while fulfilling the amount of needed energy and execution within the determined time period. The needed energy is finally acquired from an energy source for use when executing the data processing task.
