Interview with Nanjing Bank on DevOps Assessment

Background : On December 26, 2022, the China Academy of Information and Communications Technology (CAICT) announced the latest batch of DevOps and AIOps standard evaluation results. Nanjing Bank’s digital credit card project was evaluated against the DevOps Capability Maturity Model and achieved Continuous Delivery Level 3 , indicating a leading domestic capability.

Interviewee : Yu Jie, Deputy General Manager of the Information Technology Department at Nanjing Bank.

Company and Project Overview

Founded in 1996, Nanjing Bank is a listed commercial bank focused on digital transformation. The digital credit card project follows a “cloud‑based, online, intelligent” strategy, delivering a fully online credit‑card experience via mini‑programs and public accounts, creating a closed loop of acquisition‑activation‑benefits‑repurchase.

Motivation for Joining the DevOps Assessment

The bank adopted the DevOps Level 3 standard to respond quickly to business changes, improve delivery efficiency, and validate the effectiveness of its agile transformation.

Benefits and Impact

Following the DevOps standard, the project evolved from basic automated build, deployment, and release to a pipeline that includes unit testing, code scanning, automated testing, and strict quality gates, resulting in significantly higher delivery efficiency and faster innovation.

The initiative also enhanced team capabilities, creating a pool of DevOps talent.

Key Metrics

The bank benchmarked against 49 DevOps capability items, identified gaps, and achieved notable improvements in continuous‑delivery capability.

Technical Architecture

The front‑end relies on WeChat mini‑programs and public‑account ecosystems. The back‑end is built on the “XinYun+” cloud platform using the SOFA distributed service architecture, providing unified middleware management, high availability, and scalability for complex internet‑scale transactions.

Challenges Faced

Integration of heterogeneous tools and platforms required substantial effort to build a unified DevOps toolchain. Additionally, team members balanced regular development tasks with the tight schedule of the DevOps pilot.

Future Plans

The bank intends to codify DevOps practices into its software process management system and propagate the successful model to other projects, further elevating overall engineering capability.

Industry‑Wide DevOps Adoption

Statistics (as of December 26, 2022) show the number of assessments completed by major state‑owned, joint‑stock, and city‑commercial banks, illustrating growing adoption of DevOps standards across the financial sector.

DevOps Capability Maturity Model

The DevOps Capability Maturity Model was jointly developed by CAICT, the Cloud Computing Open Source Industry Alliance, the Efficient Operations Community, and leading internet companies. It is the most comprehensive and authoritative DevOps standard in China, recognized by the Ministry of Industry and Information Technology and adopted by many enterprises.

The model covers process management (agile development, continuous delivery, technical operations), application design, security and risk management, system and tool integration, business value management, collaborative development, and continuous testing.
