How JD.com’s Middle Platform Accelerates 618 Promo Preparation

After years of intensive 618 and 11.11 promotion cycles, JD.com’s R&D system has established a mature preparation workflow that now starts one to two months before a major sale, replacing the previous six‑month cadence.

The company’s middle‑platform strategy, announced by JD Retail’s Vice President Li Kefeng, standardizes a decade‑long accumulation of know‑how into reusable, component‑based, and platform‑oriented services that empower front‑end teams.

Data Platform : JD Retail’s data middle platform reorganizes internal data, builds a unified big‑data ingestion‑storage‑computation layer, and merges dozens of data marts into a single service. Data governance techniques such as tiered processing and cleaning improve storage and compute efficiency by over 20%.

Standardized data definitions and user‑profile tags provide a shared data service that fuels search, recommendation, advertising, and smart marketing, enabling precise user operations, target reach, conversion, and full‑link analysis for merchants.

Technology Platform : The technical middle platform, derived from JD’s B2C self‑operated experience, supports tens of thousands of marketing tactics and serves as a high‑concurrency, high‑reliability transaction backbone for e‑commerce.

JD has built a “nine‑channel” universal transaction platform covering product, order, inventory, data, membership, marketing, payment, stored‑value assets, and services, enabling seamless online‑offline, physical‑virtual, and B2B2C2M scenarios. For example, the JD Home “Tianji” project breaks inventory boundaries, allowing offline stores to fulfill online orders within an hour.

The platform’s core philosophy—"co‑build, share, standardize"—is reinforced by the recently launched ShenDeng Open Platform, which opens more than 200 products, services, and systems for internal reuse, encouraging rating, feedback, and rapid iteration.

Component‑based, "building‑block" development replaces siloed, custom‑built systems, reducing duplication and cutting development costs. Hundreds of decoupled components (e.g., product, inventory, transaction, order) can be assembled like LEGO bricks, supporting agile development across multiple fronts.

International expansion to Indonesia, Thailand, and other markets leverages the same component platform, requiring only minor localization, which saved roughly 50% of development effort and provided robust performance beyond local demand.

Li Kefeng likens the evolution to "changing a tire while driving at high speed," highlighting how the middle platform simultaneously supports rapid front‑end growth and drives continuous innovation in areas such as AR/VR and store technology.

Overall, JD.com’s middle‑platform and componentization strategy has turned large‑scale promotional events into a repeatable, efficient process, shortening preparation from months to under a month while fostering a virtuous cycle of technology‑driven business growth.
