Modernizing Tencent Cloud Log Service (CLS): Cloud‑Native Architecture, Challenges, and Benefits
Tencent Cloud Log Service was modernized by migrating over 95 % of its components to a cloud‑native stack of containers, Kubernetes, and declarative APIs, addressing chaotic infrastructure, stateful‑to‑stateless conversion, configuration drift, upgrade risk, elastic scaling, traffic protection and observability, which cut costs by more than 20 million CNY, reduced scaling latency by 90 %, and achieved over 99.99 % availability with petabyte‑scale burst handling.
