The need to improve the operational efficiency of terrestrial computing platforms by lowering the power usage effectiveness (PUE) figure is an important research concern. In addition, it is also important to reduce the water footprint of terrestrial computing platforms that use water for cooling and have a high water footprint. This paper proposes a network architecture that achieves the goal of reducing the PUE figure and data centre water footprint. The proposed network architecture identifies terrestrial data centres with high PUE values and replaces them with low PUE value space based data centres. This considers the case where realizing data processing via terrestrial data centres with low PUE values are infeasible. The use of terrestrial and low PUE space data centres enables the reduction of PUE (improving efficiency) the water footprint. Analysis shows that the PUE is enhanced by 30.5% on average. The water footprint is reduced by 58.1%.
