Why Alibaba Cloud Calls Its ‘Thick Middle Platform’ a New Operating System

01

In his recent talk, Zhang Jianfeng emphasized the need to build deep foundations, a thick middle platform, a strong ecosystem, and excellent services . He argued that traditional information systems, which only handled simple business flows, must now address data flows, mobility, and AI‑driven big‑data analytics.

He described this evolution as requiring a new type of operating system —beyond the classic Windows‑style processing system—capable of supporting big data, intelligence, IoT, and mobile development, making application creation easier.

The middle platform, according to Zhang, is essentially a cloud‑era, big‑data‑era, intelligent‑era, mobile‑era new operating system .

Alibaba’s middle platform differs from the earlier “big middle platform, small front‑end” concept; it has been upgraded to a new operating system rather than a mere organizational unit.

Rather than a single centralized middle‑platform department, each business unit (e.g., Alipay, Taobao/Tmall, Cainiao) now maintains its own middle platform, providing services to related business lines. This reflects the shift to “mutual middle platforms”.

Consequently, Alibaba has effectively “disassembled” the traditional middle platform—each unit functions as a middle platform, continuously sinking capabilities and delivering them outward.

The driving force behind these changes is Alibaba’s KPI‑oriented culture, where performance metrics heavily influence promotions and bonuses. While the original middle‑platform strategy has fulfilled its historical mission, its construction remains a long‑term effort, especially for Alibaba Cloud, which must still meet its KPIs.

Under the “mutual middle platform” model, Alibaba Cloud’s technical, business, and data middle platforms are tightly integrated, forming a comprehensive commercial operating system ready for external delivery.

In summary, the key points are:

Alibaba redefines the middle platform as a new operating system suited for cloud, big data, AI, and mobile eras.

This operating‑system model better manages complex commercial ecosystems and enables new business forms.

Alibaba has already “disassembled” the traditional middle platform; every business unit now acts as a middle platform.

The middle‑platform strategy, though completed historically, continues as a long‑term construction effort.

These insights illustrate how Alibaba Cloud is positioning its middle platform as a foundational operating system for the digital age.
