South Korea explores distributed cloud strategies amid rising geopolitical risks

In response to recent outages and wartime threats, South Korea is considering innovative data storage solutions, including cross-border backups and modular centres, to enhance resilience and protect critical public information.

The recent spate of cloud outages and wartime disruptions has sharpened debate in South Korea over where critical public data should live, and how it can be kept safe when physical infrastructure is under threat. After drone strikes damaged AWS facilities in the Middle East in March and a separate overheating fault caused a major AWS outage in North Virginia on 8 May, policymakers and industry figures have begun arguing that resilience, not simple domestic storage, should guide national data strategy.

The argument runs counter to a strict interpretation of data sovereignty. Gartner warned recently that keeping sensitive data inside national borders at all costs can make it harder to preserve in a war or other emergency, because concentration creates a single, highly vulnerable target. In South Korea, where the threat from North Korea is longstanding and locations of major digital infrastructure are often widely known, IT executives say the question is no longer merely where data sits, but whether it can survive a strike, blackout or sabotage attempt.

Supporters of a more distributed model point to Ukraine’s response after Russia’s 2022 invasion. According to the report cited in the Korean piece, the Ukrainian government changed rules that had required key state data to remain on domestic servers, then worked with AWS to move more than 10 petabytes of records, including material from more than 50 agencies, to overseas cloud systems. The purpose was not convenience but continuity: keeping core public records and financial services accessible even as the war intensified.

Japan has offered another precedent. After the 2011 earthquake and tsunami, some companies established backup data centres in Busan and elsewhere as a hedge against future disasters, while SoftBank and KT cooperated on a facility in Gimhae before SoftBank later withdrew from the arrangement. Former Estonian chief information officer Arvo Ott has also argued that key state functions are now deeply dependent on digital systems, making off-site protection a strategic necessity rather than a technical luxury.

Against that backdrop, some experts are urging a formal dual-backup arrangement between allies. One proposal would see countries place redundant facilities on each other’s soil, or even on embassy grounds, so that one side’s disruption would not cripple both. Others are pushing modular data centres, which can be built in roughly three months and moved or rebuilt far faster than conventional facilities, as a more flexible way to spread risk. Elice Group chief executive Kim Jae-won said overseas build-outs could preserve a backup system even if domestic war or disaster struck, while Korea University professor emeritus Lim Jong-in suggested a South Korea-Japan arrangement backed by the United States could merit consideration.
