Tenant Autonomy & Isolation In Multi-Tenant Kubernetes Clusters - A Comprehensive Guide
summary
Claims that running a per-tenant control plane as a pod inside a namespace lets teams have full cluster APIs without thousands of real clusters, using vcluster with a syncer that copies virtual objects to the host cluster and relies on normal schedulers. Demonstrates network policies, resource quotas, limit ranges and OPA/JS policy, cites 40 million virtual clusters created historically and an EKS cost example of less than $90/year, and reports it works with no inherent runtime performance hit.
