- Alex Rough argued in 2025 that data infrastructure is increasingly central to military power, and the author extends that framing by introducing 'digital strategic depth' as a concept distinct from traditional geographic resilience or cybersecurity.
- Ukraine stored critical warfighting applications and data on cloud infrastructure located outside the country, using platforms like DELTA — its battlespace management system — to fuse tens of terabytes of daily data from drones, satellites, and shared intelligence.
- Iran's strikes on data centers in Bahrain and the United Arab Emirates exposed a structural weakness: redundancy models only accounted for losing a single availability zone, while attackers took multiple zones offline simultaneously.
- Microsoft's defense and national security policy lead for Asia authored the piece, disclosing a direct commercial interest in hyperscale cloud adoption and framing the argument as architectural philosophy rather than a product pitch.
- The three pillars of digital strategic depth are dispersion (deliberate distribution across geographies and jurisdictions), elasticity (the ability to shift workloads and regenerate compute in response to attack), and optionality (independence from vendor lock-in and regulatory single points of failure).
- The U.S. Air Force was already collecting approximately six petabytes of data per day over a decade ago — equivalent to nearly a century of high-definition video — illustrating how military power has become fundamentally data-driven.
Why it matters: The piece directly challenges the policy default among allied governments toward data localization as a sovereignty measure, arguing that concentrating infrastructure in single jurisdictions creates the very vulnerabilities localization is meant to prevent. Procurement and cloud-acquisition strategies across NATO and Indo-Pacific partners now face a concrete trade-off: fortress-style sovereignty reduces survivability rather than enhancing it, per documented attacks on data centers in Bahrain and the UAE.
