Alibaba Cloud wants to measure it in weeks. The Chinese cloud giant has unveiled CUBE 5.0, a modular data-center architecture that it says can deliver fully operational AI data centers in just 100 days. Alibaba Cloud is claiming it can compress that entire process into roughly three months, while cutting overall construction costs by more than 10%. Alibaba Cloud is also planning to more than double its global modular data-center production capacity in 2026 to keep pace with demand. The system has also received certifications in Europe and Southeast Asia, signaling that the company is positioning CUBE 5.0 for international deployments rather than treating it as a domestic-only solution.
