# Kloudfuse Install Prerequisites

Review the hardware, software, and cloud prerequisites required before installing Kloudfuse on a Kubernetes cluster running on GCP, AWS, or Azure.

## Prerequisites

Before you begin, ensure the following requirements are in place:

| Requirement                | Details                                                                                                                                                                                           |
|----------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Kubernetes cluster         | A cluster running on GCP (GKE), AWS (EKS), or Azure (AKS). The cluster can be dedicated to Kloudfuse or shared with other application workloads.                                                  |
| Node resources             | At least 16 vCPUs and 128 GB memory available across the cluster. For production deployments, see [Cluster Configuration](https://docs.kloudfuse.com/platform/4.1.0/administration/clusters/overview/)       to size and isolate node pools by workload type. |
| Persistent Volume Claims    | The cluster must support dynamic PVC provisioning. Kloudfuse uses persistent volumes for its storage components.                                                                                  |
| Helm                       | Version 3.10.0 or later. Used to install and upgrade the Kloudfuse stack.                                                                                                                        |
| kubectl                    | Configured to communicate with your target cluster.                                                                                                                                               |
