How Alibaba Built Its Scalable Business Middle Platform: Architecture & Lessons

01 Alibaba IT Architecture Overview

Alibaba's IT stack is presented from the bottom up, starting with the infrastructure service layer (data‑center hardware), followed by the middle‑platform technical support platform that includes distributed service frameworks, databases, messaging, storage, transactions, and real‑time monitoring.

The business middle platform abstracts core capabilities such as transaction, payment, marketing, settlement, user, and account services, while the front‑end applications (e.g., new retail, finance, logistics, tourism) consume these capabilities.
