# Kubernetes cluster requirements

Your cluster must provide enough capacity for the deployment scale you expect, and you set that scale through a resource profile. This topic covers the available profiles and the namespace you install into.

### Resource profiles <a href="#resource-profiles" id="resource-profiles"></a>

The Harness Platform uses **resource profiles** to match your deployment scale. Select a profile based on your expected usage.

The following table lists each profile with the concurrent pipeline capacity, the team size it suits, and the YAML file that defines it.

| Profile    | Concurrent Pipelines | Recommended Team Size | YAML File              |
| ---------- | -------------------- | --------------------- | ---------------------- |
| **Small**  | Up to 50             | Fewer than 50 users   | `override-small.yaml`  |
| **Medium** | Up to 200            | 50 to 200 users       | `override-medium.yaml` |
| **Large**  | Over 200             | 200+ users            | `override-large.yaml`  |

Set the profile during installation.

{% tabs %}
{% tab title="helm" %}

```yaml
cluster:
  profile: medium
```

{% endtab %}

{% tab title="clustermgr" %}

```bash
--pi-set cluster.profile=medium
```

{% endtab %}
{% endtabs %}

For detailed resource allocations per profile, see the [Harness resource profiles documentation](/self-managed-enterprise-edition/use-self-managed-enterprise-edition/smp-basic-configuration.md#resource-profiles).

### Namespace configuration <a href="#namespace-configuration" id="namespace-configuration"></a>

Install the platform into a dedicated namespace. Specify the namespace with whichever method you use to install.

{% tabs %}
{% tab title="helm" %}
Use `helm install ... -n <namespace> --create-namespace`.
{% endtab %}

{% tab title="clustermgr" %}
Use `--namespace <namespace>`. The default namespace is `harness`.
{% endtab %}
{% endtabs %}
