Alibaba Cloud’s New Thick Mid‑Platform: From Mid‑Platform to a New Operating System

Readers asked why Alibaba claimed to have dismantled its mid‑platform only to say it is building a thicker one; the author reviews Alibaba Cloud President Zhang Jianfeng’s recent talk and offers personal insights.

In the talk, Zhang emphasized four goals: deep foundations, a thick mid‑platform, a strong ecosystem, and excellent services.

He argued that modern information systems now involve not only business processes but also data flows, mobility, and AI‑driven big‑data analytics, requiring a new type of operating system that supersedes the traditional Windows‑style processing system.

“The mid‑platform is actually a new operating system for the cloud, big‑data, intelligent, and mobile eras.”

The author distinguishes Alibaba Cloud’s mid‑platform from Alibaba’s earlier “big mid‑platform, small front‑stage” model, stating that the former has evolved into a comprehensive operating system that manages resources across hardware, software, and data.

He explains the difference between a platform (rules, standards, role‑based permissions) and an operating system (resource management, program control, user interface support), noting that the latter’s scope exceeds that of a platform.

Regarding the question of whether Alibaba has truly dismantled the mid‑platform, the author cites a conversation with an Alibaba P9 architect who confirms that each business unit now hosts its own “mid‑platform” (e.g., payment, retail, logistics), effectively meaning the central mid‑platform no longer exists.

This decentralization enables Alibaba Cloud to further embed mid‑platform capabilities into its commercial operating system and support external output.

The article also attributes the continued focus on mid‑platform initiatives to Alibaba’s KPI‑driven culture, where performance metrics drive the sustained development and promotion of the platform strategy.

In conclusion, the author summarizes five key points: (1) Alibaba’s new definition of the mid‑platform as a cloud‑era, big‑data, intelligent, mobile operating system; (2) the operating‑system model better manages complex commercial ecosystems; (3) the original mid‑platform has been dismantled, with each unit acting as its own platform; (4) the mid‑platform has evolved into an “inter‑mutual” stage; and (5) while the mid‑platform strategy has fulfilled its historical mission, its construction remains a long‑term effort.
