The next phase of the digital economy will not be defined by innovation. It will be defined by control.Artificial intelligence, cloud, connectivity, and data infrastructures have converged into a single system — the Digital Backbone — that now underpins how organisations operate, compete, and exercise power.What was once considered technology infrastructure has become a strategic governance issue.As enterprises accelerate the adoption of AI and platform-driven operating models, dependencies on hyperscalers, data ecosystems, and digital supply chains are reshaping corporate strategy, operational resilience, and risk exposure.This book examines how the Digital Backbone is redefining governance at board and executive level across strategic, operational, and risk dimensions.Because in the digital economy, infrastructure is no longer just an operational foundation. Infrastructure defines control, resilience, and power.
