| Virtual IP | kube-vip | Virtual IP for high availibility |
| Load Balancer | MetalLB | External load balancer for accessing cluster services |
| Ingress | Nginx Ingress Operator | Traffic distribution and load balancing |
| Storage | NFS Subdir External Provisioner | NFS provisioner provides storage for apps |
