# Virtual Machine (VM) Deployment

In most cases, OvalEdge is installed on a virtual machine (VM). The operating system can be selected based on organizational preference.

Before installing the OvalEdge application on a VM, the following steps must be completed:

1. Verify that the hardware meets the specifications listed in the **Hardware Requirements** section.
2. Install the software specified in the **Software Requirements** section.
3. Complete the mandatory pre-installation steps outlined in the **Installation Activities** section.

## Prerequisites

### Hardware Requirements

### **Single Virtual Machine (All-in-One VM)**

Installing all components—including the database, Elasticsearch, and application server—on a single VM is recommended only for the Essential edition or for proof-of-concept (POC) environments. This configuration is not suitable for multi-user deployments.

**Supported Operating Systems**:

* Windows
* Linux: Ubuntu and RHEL

**Recommended Hardware:**

| HARDWARE                                      | ESSENTIAL                               | PROFESSIONAL                        | ENTERPRISE                            |

{% hint style="warning" %}
\*A single VM is not recommended for Professional and Enterprise packages since it will result in performance issues.
{% endhint %}

### **Multiple VMs (Separate VMs for different components)**&#x20;

It is recommended to use:

* One VM for the Application Server (AS)
* A separate VM for Elasticsearch (ES)
* A separate VM or cloud-hosted database service

As Amazon RDS manages backups and recovery tasks, using RDS or an equivalent cloud database service is recommended for the database.

For non-production or proof-of-concept (POC) workloads, a separate database environment is advised. In such cases, the AS and ES components can be hosted on a single VM.

**Recommended Hardware for the Application Server(AS) VM**
