# Concepts & Limits (Neon Kubernetes Engine)

Neon Kubernetes Engine (NKE) provides **managed Kubernetes** with versioned control planes and node pools.

> Insert screenshot of **Kubernetes → Clusters** here

## Key concepts 💡

* **Cluster:** Managed control plane with one or more **node pools**
* **Node pool:** Set of worker nodes sharing the same size/image
* **Versioning:** Supported K8s releases with scheduled deprecation
* **Networking:** VPC-attached; supports LoadBalancers and Ingress
* **Storage:** CSI-backed persistent volumes from block storage tiers

## Typical limits (example)

| Item                 | Default      | Notes                       |
| -------------------- | ------------ | --------------------------- |
| Clusters per project | 5            | Per region                  |
| Nodes per cluster    | 50           | Across all pools            |
| Node pool count      | 10           | Per cluster                 |
| PV size              | Up to 10 TiB | Depends on tier             |
| K8s versions         | N, N-1       | Oldest retired periodically |

> Actual limits may vary by region/plan; see **Quotas**.
