Understanding Alibaba Cloud’s Infrastructure Network: History, Challenges, and Operational Practices

From the first Chinese email sent in 1987 to the rapid expansion of internet access in the 1990s, the piece outlines how the network has become a fundamental layer of China’s digital economy, especially after the 2020 pandemic accelerated the adoption of 5G, cloud computing, big data, AI, and blockchain.

The 2021 Key Information Infrastructure Security Protection Regulation highlights the nation’s heightened focus on the security of critical network infrastructure, defining the responsibilities of “operators” who must protect these assets.

Alibaba Cloud’s Infrastructure Network Operations team, responsible for planning, building, and maintaining a global network serving millions of servers, follows a strict “no same‑flight” rule to mitigate the risk of simultaneous team loss, emphasizing 24/7 emergency response and high‑availability services.

Operating at massive scale introduces several challenges: the “scale effect” amplifies minor issues; complex hardware‑software environments create integration and management difficulties; and global variations in regulations and infrastructure add further complexity.

To address these, the team adopts a four‑pillar safety production methodology—prevention, drills, defense, and emergency response—anchored by top‑down design, a strong safety culture, rigorous quality and risk‑control processes, regular fault‑simulation drills, and a dedicated 7×24 rapid‑response team.

Looking ahead, Alibaba Cloud aims to continue advancing cloud‑based network infrastructure, leveraging emerging technologies to strengthen security, improve operational efficiency, and support the ongoing growth of the digital economy.
