Abstract
Data centres play an important role in developing machine learning algorithms and in wireless networks. The large scale use of data centres increases the operational costs for cloud computing service providers. The operational costs can be reduced by siting data centres in locations such as the stratosphere. The siting of data centres in stratosphere reduces cooling costs and enhances the power usage effectiveness (PUE). This paper examines the PUE improvement obtainable with data centres located in the stratosphere. Performance evaluation shows that the stratosphere’s cooling capacity increases with the proportion of green house gases. The PUE is enhanced by at least 27% on average when 33.3% of data centres in a cloud platform are located in the stratosphere. The PUE is enhanced by up to 40.1% on average when 50% of data centres in a cloud platform are located in the stratosphere.
