Building large-scale Internal Developer Platforms: Core Principles
summary
RTL Data describes a platform used by over 30 heterogeneous teams that produces 400 GCP projects and 100 GKE clusters in 2–3 years. It centralizes metadata in a single source of truth, automates provisioning with Terraform and GitLab CI, and integrates Argo CD, Prometheus/Grafana/OpsGenie, Vault and Airflow. Infrastructure is decentralized per product team with small clusters and sandboxes, the stack is intentionally opinionated, and the core operational claim is: prioritize product thinking, tight automation, and clear permission boundaries.
