summary
American Airlines describes a production multitenancy platform built on Runway (Backstage) that uses custom CRDs plus an operator to turn simple app specs into Kubernetes resources, GitHub + Argo CD ApplicationSet for fleet-wide manifests, and Azure AKS with Azure CNI after hitting a 400-node limit. The fleet runs about 30 clusters (4 active clusters host 659 namespaces and 1,736 deployments last week), autoscaling misconfigs once spun up 20 nodes costing ~$10,000/month, and CRD-driven templates cut onboarding to 1–2 weeks.
