Ant Financial’s Fifteen‑Year Technology Architecture Evolution and the Future of FinTech

On May 6, 2019, Ant Financial’s deputy CTO Hu Xi delivered a presentation titled “Ant Financial’s Fifteen‑Year Technology Architecture Evolution” at QCon, summarizing how the company has rebuilt payment and micro‑loan services using five core BASIC technologies: Blockchain, Artificial Intelligence, Security, IoT, and Cloud Computing.

Main viewpoints:

1. Continuous improvement of computing capability is the foundation for future fintech scenarios.

2. Financial transaction systems rely on distributed middleware and highly available distributed databases that guarantee zero data loss and uninterrupted service.

3. The future of financial‑grade distributed systems is cloud‑native, with middleware functions exposed via Service Mesh and security‑enhanced containers.

4. Open, pluggable computing architectures—unified storage, interchangeable engines, and intelligent SQL—will drive the next wave of Big Data and AI integration.

5. Ant Financial collaborates with UC Berkeley on the Ray engine to provide a multi‑modal, function‑programming‑friendly distributed compute platform.

6. The open‑source project SQLFlow abstracts end‑to‑end data‑to‑model workflows, making AI development as simple as writing SQL.

The talk then details three concrete pillars:

1. Financial‑grade cloud‑native architecture: High‑availability, consistent distributed databases (OceanBase), three‑site five‑center active‑active deployment, and a technical‑risk‑as‑a‑Service (TRaaS) system that detects and recovers from failures within minutes. Security containers (Kata) and Service Mesh are positioned as essential infrastructure.

2. Open intelligent computing for data intelligence: A unified storage layer, pluggable compute engines (streaming, graph, ML), and a standardized intelligent SQL gateway enable seamless OLTP/OLAP processing, reducing development cost and complexity.

3. BASIC College talent program: An internal training system focused on the five BASIC domains, inviting external experts to cultivate the next generation of fintech engineers.

Overall, Ant Financial advocates a cloud‑native, open, and secure foundation that abstracts complex financial‑grade capabilities, allowing developers to focus on business logic while the platform ensures reliability, scalability, and intelligent data processing.
