# System requirements - PV autoscaling

This topic describes the following minimum requirements and settings that are verified to work with PV autoscaling:

- [Operating systems](/v1/docs/system-requirements-pvs-autoscaling#supported-operating-systems)
- [Instance settings](/v1/docs/system-requirements-zesty-disk-for-k8s#required-instance-settings)
- [Infrastructure](/v1/docs/system-requirements-zesty-disk-for-k8s#required-infrastructure)

### Supported operating systems

| Operating system | Type | Release | Processor | Notes |
| --- | --- | --- | --- | --- |
| Linux |  |  |  |  |
|  | Amazon Linux | 2023 | Intel, ARM-based |  |
|  | Amazon Linux | 1, 2 | Intel, ARM-based |  |
|  | Bottlerocket | 1.24.x | Intel, ARM-based | EZswitch is not supported |

### Required instance settings

These network settings are required on all cluster nodes to be compatible with PV autoscaling.

| Setting | Requirements |
| --- | --- |
| Network settings | **Outbound security group** - Type = HTTPS - Destination = Anywhere-IPv4 (0.0.0.0/0 is the one that is needed, despite the AWS warning.) |

### Required infrastructure

- Your VPC must have outbound access to the internet. If this is not possible, Zesty Disk supports secured connectivity using AWS PrivateLink. For more information, see [Enable PrivateLink for Zesty Disk](/v1/docs/enable-privatelink-for-zesty-disk).
- Zesty Disk requires CPU and RAM resources to operate. For more details, see the PV autoscaling Helm chart at [https://zesty-co.github.io/zesty-helm/values.yaml](https://zesty-co.github.io/zesty-helm/values.yaml).
