Lingque Cloud’s Five‑Year Cloud‑Native Journey and Open‑Source Projects Kube‑OVN and Captain

On November 6, the Tencent Techo Developer Conference in Beijing featured a keynote by Daniel, DevOps lead at Lingque Cloud, titled “Lingque Cloud Cloud‑Native Product Practice Path,” where he shared the company’s five‑year cloud‑native evolution, emphasizing Kubernetes network management and Helm distribution improvements.

He described how Lingque Cloud’s delivery methods progressed from raw source code, container images, and Kubernetes YAML files to Helm charts, and how the business model shifted from public‑cloud container services to multi‑cluster private PaaS and finally a private cloud‑native PaaS, with the delivery pipeline evolving from basic builds to CI/CD and integrated DevOps.

In 2016 the product was containerized, achieving twice‑weekly deployments that cut iteration time by 50%; in 2017 Kubernetes became mainstream, enabling ten weekly releases of ten‑minute deployments and private‑cloud deployments; by 2018 digital‑transformation demands led to the adoption of Service Mesh and Istio; this year the architecture migrated fully to native Kubernetes, reaching 50 daily releases of five minutes each.

To accelerate iteration and validation, Lingque Cloud provides tools and products that help customers adopt cloud‑native practices, and it addresses micro‑service governance challenges by launching the enterprise‑grade API Management Platform (AMP) for traditional enterprises.

Daniel then introduced two key open‑source projects: Captain, a Kubernetes controller built on Helm 3 that resolves Helm 2’s limitations (such as Tiller coupling and resource conflicts), and Kube‑OVN, which integrates OVN networking into Kubernetes, bringing OpenStack‑level features like VPC, subnet, multi‑tenancy, QoS, and encryption to cloud‑native environments.

Both projects are now in production, and the audience is encouraged to try them and provide feedback.
