Five Methodologies for Backend Development: Quantification, Comparison, Documentation & Process, Standardization & Unification, Automation

The author, a backend engineer with six years of experience at Tencent, shares five practical methodologies that can improve efficiency and quality for backend developers.

1. Quantification – Transform abstract concepts into measurable data. The article distinguishes between technical metrics (server/container stats, performance baselines, monitoring data) and business metrics (room count, concurrent users, request latency, error rates). Tools such as Tencent Monitor (TMP), Prometheus, ELK, and custom dashboards are referenced for collecting and visualizing these data.

2. Comparison – Use year‑over‑year, month‑over‑month, and before‑after analyses to detect trends, spot anomalies, and guide optimization. Version control (Git) and log comparison are highlighted for verifying the impact of changes.

3. Documentation & Process – Emphasize thorough record‑keeping (code comments, meeting minutes, error logs, knowledge bases) and well‑defined processes (code review, automated testing, release management, incident response). The author notes that many production incidents stem from missing or non‑standard procedures.

4. Standardization & Unification – Adopt consistent coding standards (language‑specific style guides, CodeCC checks), unified documentation templates (iwiki), and a common technology stack. Reuse existing components and libraries, avoid “wheel‑reinvention,” and conduct regular technical reviews to keep the stack optimal.

5. Automation – Implement CI/CD pipelines (e.g., Blue Shield, Zhiyan CI), automated testing frameworks (QTA, Xinghai), and scripting (Shell, Python, Node.js) to reduce manual effort and human error. Monitoring and alerting (cloud monitoring, Tianji Ge) are integrated to ensure system stability.

The article concludes with a call for developers to adapt these methods to their own projects, continuously refine their practices, and share experiences within the community.
