As corporate digital transformation (DX) accelerates through the expansion of cloud and AI, several easily overlooked “blind spots” are emerging. This session will explore critical challenges often sidelined in the pursuit of rapid digitalization. Key topics include the complexities of digital sovereignty and regress costs in public cloud environments, along with the dual challenge of ensuring data confidentiality while maximizing AI‑driven insights. We will also examine the financial and environmental impact of increasing power consumption in IT infrastructures. Furthermore, we will consider strategic requirements for enterprises and data center operators as digital and social infrastructures converge. This includes Japan‑specific contexts such as facility constraints for new cooling technologies, disaster resilience, and economic security. Attendees will gain essential viewpoints for building a sustainable and robust IT foundation.
