If data provenance is the legal perimeter of the training set, the cloud is the physical substrate that dictates its performance ceiling. We are moving past the era of digital sovereigntyโwhere we primarily cared where data satโinto an era of Architectural Capture, where the primary differentiator is who owns the silicon and the interconnects.
When I previously analyzed Europeโs struggle for digital sovereignty, the focus was on residency and jurisdiction. Today, the industry is pivoting toward Vertical Integration. The “General Purpose AI Cloud” is a dying breed. Googleโs strategic decision to prioritize internal TPU (Tensor Processing Unit) allocation over external sales, and Appleโs retreat into “Private Cloud Compute,” signify a retreat from horizontal scaling toward a Closed-Loop Stack.
