> Exactly what ships today — capabilities, limits, and what is not offered yet

## Limits

| Limit                                  | Value                                                                                                                                               |

| Clusters per account                   | 10 (contact support to raise)                                                                                                                       |
| Node pools per cluster                 | unlimited; ≥1 required                                                                                                                              |
| Nodes per pool                         | 2–20                                                                                                                                                |

| Storage nodes                          | 0, 2 or 3; 10–1000 GB data disk each                                                                                                                |
| MetalLB address pool                   | up to 32 addresses                                                                                                                                  |
| Kubernetes versions                    | up to three minor versions with in-place upgrades — see [Supported versions](/products/build/kubernetes/details/supported-versions)                 |
| Region                                 | us-east                                                                                                                                             |
| Connections / requests / Ingress hosts | **No platform-imposed limits** — throughput is bounded only by your cluster's dedicated gateway capacity (per-cluster, unaffected by other tenants) |

## What's included

* Managed, free control plane (optional 3-master HA), RKE2 + Cilium
* Node pools with labels, taints and autoscaling (all pools share the cluster's worker plan)
* Drain-first scale-down (PodDisruptionBudgets honoured, never force-deleted)
* Admin kubeconfig; full REST API; dashboard with workloads, pods, live logs, metrics and control-plane health
* App Hub one-click installs with HTTPS/TCP expose
* Dedicated VPC, gateway firewall (baseline or your security group), Traefik and MetalLB options, Longhorn storage nodes
* [99.90% monthly SLA](/products/build/kubernetes/details/sla) (endpoint path on HA clusters) and 24/7 support

## Not offered yet

Honest list of gaps we're working on:

* **Kubeconfig rotation / short-lived credentials** — the kubeconfig is a long-lived admin credential; treat it accordingly
* **Multiple regions** — us-east only
* Windows nodes, GPU nodes, IPv6
