Deploying a multi-tenant Kubernetes cluster with RBAC policies offers significant organizational advantages through optimized resource utilization and controlled access.

Cost Efficiency
Reduced infrastructure overhead: Shared clusters eliminate redundant control planes, lowering cloud costs by 40-60%.

Higher resource density: Achieve better hardware utilization through container consolidation, preventing underused nodes

Centralized management: Unified monitoring systems and shared ingress controllers reduce operational expenses

Security & Compliance
Granular access control: RBAC enforces least-privilege principles through namespace-scoped

Isolation guarantees: Network policies restrict cross-tenant communication while resource quotas prevent resource exhaustion
Operational Advantages: Teams self-manage workloads within their namespaces without cluster provisioning delays

Simplified scaling: Add tenants through namespace creation instead of full cluster deployments
