How China’s Leading Banks Achieve DevOps Maturity: Real‑World Case Studies

Overview of the DevOps Capability Maturity Model

Amid digital transformation, enterprises adopt DevOps to boost efficiency. The "R&D‑Operations Integrated (DevOps) Capability Maturity Model" led by the China Academy of Information and Communications Technology (CAICT) provides high‑value guidance, helping leading firms improve IT capabilities, integrate teams, and better support business systems.

Participating State‑Owned Banks and Assessment Count

Four major state‑owned commercial banks—Industrial and Commercial Bank of China (ICBC), Agricultural Bank of China (ABC), Bank of China, and China Construction Bank Financial Technology (CCB‑FinTech) – together with the Credit Card Center of Bank of Communications – have taken part in the DevOps maturity assessments, totaling 14 projects.

ICBC – eLife & Intelligent Advisory System

The "eLife" platform integrates lifestyle, consumption, and finance for ICBC’s credit‑card customers, serving tens of millions of users with daily active users around 500,000. Large‑scale DevOps rollout involved strong executive support, a dedicated continuous‑delivery team, tool‑chain service‑packaging, and cultural promotion to ensure adoption.

The Intelligent Advisory system leverages big data and AI to provide automated investment services, built on a fully cloud‑native architecture using ICBC’s private IaaS and PaaS clouds. It achieves high availability, elastic scaling, fine‑grained logging, automated cloud operations, and end‑to‑end DevOps, delivering sub‑0.2‑second response times.

ABC – Five Projects in One Evaluation

ABC evaluated five projects in a single assessment: a credit‑mid‑platform, personal online banking, distributed application interconnect platform (AIR), VAT input‑tax management, and a financial mini‑store. These span Java and C# stacks, cloud‑on‑cloud, middle‑office front‑end, service‑oriented and micro‑service architectures, covering diverse business domains.

The initiative tackled cross‑department coordination, tool‑chain localization, metric‑system construction, institutional breakthroughs, standards comprehension, and pandemic‑induced remote‑work challenges.

The mobile banking deposit‑loan module, serving over a hundred million users with daily transaction volume exceeding 40 million, employs Vue for the front‑end and ABC’s proprietary Taihang framework for the back‑end, featuring offline‑package mechanisms, hot‑fixes, and automated deployment.

Bank of Communications – New Generation Internet Platform

The Credit Card Center’s new internet platform, built on the self‑developed micro‑service framework "Touda," offers high availability, high concurrency, low latency, and strong scalability. Integrated with a full‑process DevOps toolchain, it improves development efficiency and shortens delivery cycles.

Security and Risk Management (Standard 6)

ICBC’s mobile banking project adopted CAICT’s DevSecOps standard, establishing a systematic security development framework covering organization responsibilities, tool maintenance, third‑party software, data management, and infrastructure. It embeds lightweight threat modeling, open‑source component analysis, and security requirements into the tool platform and daily inspections.

The project faces challenges such as complex customer environments, numerous business scenarios, massive user base (>4 billion), rapid iteration cycles, and the need for coordinated security awareness across many participants.

System and Tools (Standard 8)

Bank of China’s DevOps Cloud Platform provides enterprise‑level CI/CD, testing, deployment, quality management, security control, and artifact management across diverse product lines. Recent improvements raised build success rates by 11 % and deployment success rates by 22 %, halving average build time and cutting pipeline execution time by 40 %.

CCB‑FinTech’s "Yaoguang" agile R&D platform supports end‑to‑end development, DevOps toolchains, low‑code development, and metric collection for all 38 branches, delivering more robust and standardized pipelines.
