===== iqxWEB Next - Server Environment Requirements =====

**Document Version:** 1.0\\
**Date:** 23 September 2025

This document outlines the minimum and recommended server specifications required for a successful deployment of the iqxWEB application stack. Adhering to the recommended specifications is crucial for ensuring optimal performance, stability, and scalability in a production environment.

----

==== System Specifications ====

The following tables detail the resource requirements. The **Minimum** configuration is suitable for testing or light production use with a limited number of concurrent users. The **Recommended** configuration is designed to provide a robust and responsive experience for a moderate user load.

=== Table 1: Linux Server Requirements ===

^ Specification              ^ Minimum Configuration   ^ Recommended Configuration ^
| **CPU** | 2 vCPUs                 | 4 vCPUs                  |
| **RAM** | 4 GB                    | 8 GB                     |
| **Storage** | 40 GB                | 40 GB          |

=== Table 2: Windows Server Requirements ===

^ Specification              ^ Minimum Configuration   ^ Recommended Configuration ^
| **CPU** | 2 vCPUs                 | 4 vCPUs                  |
| **RAM** | 8 GB                   | 16 GB                     |
| **Storage** | 60 GB               | 60 GB          |

==== Operating System Requirements ====

=== Linux Distributions ===

A modern, 64-bit server distribution is required. We recommend any of the following Long-Term Support (LTS) versions:
  * Ubuntu Server
  * Debian
  * Red Hat Enterprise Linux (RHEL) family (e.g., RHEL, Rocky Linux, AlmaLinux)
  * SUSE Linux Enterprise Server

=== Windows Server ===

  * Windows Server 2025 or later is required.
  * **Hardware-assisted virtualization** (e.g., Intel VT-x or AMD-V) must be enabled in the BIOS/UEFI.
  * The **Windows Subsystem for Linux (WSL) 2** feature must be installed and enabled, as the application runs within Linux containers.

----

==== Prerequisites & Network Configuration ====

Please ensure the following requirements are met prior to the scheduled installation date.

  * **Public Accessibility:** The server must be accessible from the internet on a static public IP address. Alternatively, a professionally configured reverse proxy can be used to forward traffic to the server.
  * **Firewall Rules:**
    * Inbound traffic must be permitted on TCP ports ''80 (HTTP)'' and ''443 (HTTPS)''.
    * Outbound traffic must be permitted from the web server to the IQXHub (Bridge Server) host over its designated port (typically TCP ''54000'').
  * **SSL/TLS Certificate:** A valid SSL/TLS certificate and its corresponding private key for the application's domain name must be provided to the installation team before deployment can begin.
  * **SSH Access (Linux):** For security purposes, we strongly recommend that server access be configured using SSH key-pair authentication and that password-based authentication is disabled.

----

==== Client Responsibilities ====

The client is responsible for the ongoing maintenance and security of the server environment. This includes, but is not limited to:
  * Performing regular operating system updates and security patching.
  * Implementing and managing a robust data backup and disaster recovery strategy.
  * Monitoring server performance, resource utilisation, and log files.
