This case study details the architecture of a cloud-native CI/CD platform deployed on a public cloud VPC, serving over 500 production projects. The author breaks down the design into three logical chains: the code chain (GitOps with ArgoCD), the build chain (containerized CI pipelines), and the deployment chain (multi-cluster orchestration). Key architectural decisions include network topology design for multi-tenancy, cluster planning for cost optimization, and automation of the entire delivery pipeline. The article also discusses challenges such as secrets management, artifact storage, and monitoring at scale. For platform engineers and DevOps teams, this provides a real-world blueprint for building a GitOps platform that balances performance, security, and operational efficiency.
This article presents a comprehensive architecture design for a cloud-native CI/CD platform running on public cloud, supporting 500+ projects. It covers network topology, cluster planning, and automation pipelines, offering valuable insights for platform engineers building large-scale GitOps systems.
