Deepening Cloud‑Native Innovation to Reshape Digital Productivity in 2024 Commercial Banks

Overview

Under the national "Xinchuang" (innovation and independent controllability) strategy and accelerating digital transformation, commercial banks are increasingly demanding agile, cost‑effective, and secure software development. The BanTech think‑tank seminar on 15 November 2024 gathered experts from major banks to discuss cloud‑native adoption as a key lever for faster application delivery, resource efficiency, and the "second development curve" of digital productivity.

Agricultural Bank of China – Cloud‑Native Practice

The bank advances cloud‑native across four layers: foundational services, architecture, development, and operations. Its practice focuses on three pillars:

Foundation: Building an integrated cloud platform with four "clouds" to support group‑wide scenarios, enhancing distributed database capabilities, and establishing a cloud‑native data lake based on a "one data + multiple engines" model.

Platform Capability: Creating a lightweight Serverless platform for end‑to‑end rapid delivery and a unified branch‑service cloud platform to reduce branch‑level development and operation costs.

Support Platform: Developing an in‑house chaos engineering platform for systematic fault‑scenario testing and an integrated production‑operations platform to improve monitoring and incident analysis.

Construction Bank – Cloud‑Native Evolution

Director Sun Daiyong highlighted two primary goals: agile business delivery and solving distributed‑architecture challenges via cloud‑native. Since 2016 the bank has built DevOps, container, and micro‑service capabilities, released a "Jianhang Cloud" suite with cloud‑native databases and middleware, and created pilot‑case‑driven cloud‑native sample rooms to drive full‑scale application containerization.

The bank also emphasizes security integration across the development‑operation lifecycle, moving from perimeter protection to an intrinsic, end‑to‑end protection model.

Everbright Bank – Integrated Cloud‑Native Ecosystem

Director Chen Guanghua described a holistic approach that combines cloud‑native technology with existing systems, adopts an open stance toward new models, and invests in core technology R&D. The bank’s strategy centers on a service‑mesh backbone, a full‑stack cloud platform, and low‑code intelligent development to deliver financial services, with plans to expand full‑stack cloud coverage and intelligent governance.

CITIC Bank – Cloud‑Native Practice

CTO Ma Rong outlined the bank’s three‑phase cloud‑native rollout: early foundation building (2016‑2020), progressive cloud service capability enhancement (publishing "Jianhang Cloud" products), and comprehensive cloud‑native transformation using pilot applications as templates.

Huaxia Bank – Lake‑Warehouse Big Data Platform

Data‑application expert Li Shiguang presented a cloud‑native lake‑warehouse platform that integrates data acquisition, processing, open services, and governance. The three‑system architecture includes:

Data Processing: Enhancing storage, compute, and AI capabilities across five functions.

Data Open: Multi‑modal access, accelerated queries, and API‑driven data services.

R&D Governance: Automated low‑code development, metadata management, and lifecycle governance.

Key innovations: a fully autonomous stack, consolidation of emerging big‑data technologies, unified data flow acceleration, and cross‑domain public data asset accumulation.

Beijing Bank – Container Cloud Platform

Expert Luo Shuihua described a next‑generation container cloud platform that provides multi‑tenant isolation, standardized application packaging, and a unique "single‑cluster Xinchuang hybrid scheduling" technology. Notable metrics include over 130 physical Xinchuang nodes in production, more than 150 business systems migrated to the cloud, and hybrid scheduling used by over 60 % of workloads.

Platform value is expressed in four dimensions:

Fine‑grained resource accounting for cost‑effective, low‑carbon operation.

Self‑service middleware PaaS covering multi‑version, multi‑mode lifecycle management.

Agile delivery via rapid application management, intelligent scheduling, and visual monitoring.

Regional management enabling "one cloud, multiple cores" to leverage heterogeneous compute power for Xinchuang infrastructure upgrades.

Yunyuan Data – KubeBlocks Enterprise for Xinchuang Database Cloud Services

CEO Cao Wei introduced the company’s mission to deliver cloud‑neutral, engine‑agnostic, and self‑controllable data infrastructure supporting both public and hybrid clouds. Architect Wang Hao detailed the KubeBlocks Enterprise platform, which offers:

OpenAPI‑based operational APIs for flexible, compliant database management.

Separation of volatile and stable workloads to improve resource utilization and avoid interference.

Resource pooling and cost‑optimal scheduling via mixed‑node technology.

CI/CD integration for mature Database DevOps pipelines.

Consistent management logic through a standard Operator API applicable to multiple database types.

End‑to‑end data encryption covering transport, storage, and audit.

High‑availability cluster designs for continuous operation.

Flexible backup and recovery mechanisms supporting hot‑backup, incremental snapshots, and customizable retention.

Comprehensive monitoring and alerting built on OpenTelemetry, with multi‑channel notifications.

Front‑back separation enabling tenant‑level isolation and centralized administration.

The platform targets the strategic importance of Xinchuang databases in the domestic ecosystem, addressing challenges of integration complexity, uneven vendor maturity, and the need for enterprise‑grade cloud‑native database services.

Industry Insight

Through thematic sharing and deep discussions, participants examined current cloud‑native deployment strategies, the role of cloud‑native in "dual‑mode IT" integration, and common challenges such as resource scheduling, security integration, and standardization. The collective insights point to a future where cloud‑native foundations become the backbone of banking digital transformation.
