Cloud Computing in Defence
Information superiority is critical to modern combat, and in a changing digital landscape, investment in cloud technology is paramount to maintaining these defence capabilities. During warfare, military forces must gather and analyse extensive data to stay ahead of adversaries. However, warfare has evolved from traditional battles on land, sea and air to encompass various interrelated types of war, including cyberwarfare, information warfare, and space warfare. The evolution of warfare is compounded by the effects of technology, which increase the speed at which war is fought and managed. However, the success of decision-making that modern warfare requires relies on the ability of information technology systems to rapidly process large amounts of data (Defence One, n.d.). New technology is outperforming these older IT systems, and European militaries must adopt new technology, specifically Cloud computing to maintain information superiority which underpins successful warfare. Cloud will likely serve as the backbone of all future digital defence capabilities; thus, investment in this technology is fundamental to maintaining information superiority. Cloud is more than just a storage platform as it can host various computing tools that assist in information superiority through situational awareness, contributing to efficient decision-making during conflict. In 2019, the European Defence Agency financed a study about cloud computing for the defence sector (European Defence Agency, 2024). The EDA’s study, Cloud Intelligence for Decision-Making Support and Analysis (CLAUDIA), ended this January (European Defence Agency, 2024). The study was run in collaboration with GMV, a private capital technology business group (GVM, n.d.), and The Information Processing and Telecommunications Center (IP&T Center) (European Defence Agency, n.d.). This paper explores the notion of cloud computing, and using the case studies of CLAUDIA, NATO and the UK Ministry of Defence (MoD), it delves into three uses of cloud in the defence sector, including source analysis, edge computing and multi-domain operations. Finally, the analysis discusses challenges associated with cloud technology, including digital sovereignty and the need for cultural shifts within the defence sector.
