How a Major Bank Reached Leading DevOps Maturity in Continuous Delivery

From the perspective of industry practice, standardization and tool empowerment are key to the success of technology companies. The DevOps standard and its continuous delivery pipeline platform dramatically boost software development efficiency, enabling faster, more flexible market responses and strengthening IT as a core competitive asset.

The GNSEC 2020 Global New‑Generation Software Engineering Online Summit, co‑organized by the Cloud Computing Open Source Industry Alliance, Efficient Operations Community, and DevOps Era Community, attracted over 3,000 online participants and showcased the latest research and practice in software engineering.

The summit announced the seventh batch of DevOps standard continuous delivery assessment results, including participants such as China Agricultural Bank, China Merchants Bank, Shanghai Pudong Development Bank, PICC, and Taikang Insurance.

The China Construction Bank Pacific Credit Card Center (CCB PCC) evaluated its "New Generation Internet Platform" project, which passed the level‑3 continuous delivery assessment of the "Research and Development Operations Integration (DevOps) Capability Maturity Model" conducted by the China Academy of Information and Communications Technology (CAICT). Achieving level‑3 places the center at a leading domestic level.

Interview with Wang Zhiwei, General Manager of IT Management Department, CCB PCC

Q: Please introduce your organization and the project evaluated.

A: Established in 2004, the Pacific Credit Card Center manages the bank's credit‑card business and, as of 2019, serves over 71.8 million cards and 60 million bound customers. Since 2011, the internet platform has evolved into a comprehensive, multi‑channel financial service platform serving tens of millions of users.

Q: How did you decide to join the DevOps standard assessment?

A: We closely follow industry trends and sought a standard to guide our DevOps practice. The DevOps standard offered a clear benchmark, so we selected our flagship internet platform project for a comprehensive evaluation.

Q: What benefits has the assessment brought?

A: The assessment validated our continuous delivery capabilities, highlighted strengths and gaps, and led us to build a complete DevOps toolchain that supports organization‑wide development management.

Q: What measurable improvements resulted?

A: Pipeline build time is now under 10 minutes, overall unit‑test coverage reached 60 % (new code > 80 %), interface automated‑test coverage is 100 %, production deployment failure rate is below 10 %, and we can release daily.

Q: Describe the system architecture and design.

A: The platform is built on the in‑house micro‑service framework "Touda", offering high availability, high concurrency, low latency, and strong scalability, combined with a full‑process DevOps toolchain to accelerate development and shorten delivery cycles.

Q: Was the assessment process smooth? Any challenges?

A: We prepared meticulously, addressed each weakness with targeted solutions, and continuously aligned our capabilities with the standard, resulting in a smooth evaluation.

Q: What is the biggest gain from DevOps implementation, and what are your next steps?

A: DevOps broadened our vision, identified both strengths and weak points, and improved development efficiency and team acceptance. We plan to solidify and promote the DevOps toolchain across the organization.

Q: How do you view the future of DevOps?

A: We are optimistic; DevOps aligns with industry goals of faster development, shorter release cycles, and higher efficiency. We will continue to advance DevOps to become a leading fintech enterprise.

The new generation internet platform project features a DevOps‑integrated toolchain that visualizes and automates the entire lifecycle from requirement to production, ensuring quality, improving efficiency, and enabling automated testing, code scanning, and continuous integration.

The DevOps Capability Maturity Model, the world’s first DevOps standard, was led by CAICT together with industry experts from Google, BATJ, Tsinghua University, Nanjing University, and leading enterprises. It covers agile management, continuous delivery, technical operations, application design, security, risk management, systems, and tools.
