Turnkey Office & All-in-One Server on Proxmox VE

Turnkey infrastructure engineering for companies with 10 to 50 employees on the Proxmox VE hypervisor. We consolidate database servers, network routing, corporate telephony, file storage, VPN, and automated backup systems into a single energy-efficient server without recurring hypervisor licensing costs.


Single-Host Clustered Architecture

All office IT services are cleanly segmented into isolated virtual machines and lightweight LXC containers:

               +--------------------------------------------+
               |     Physical Server / Compact Microserver  |
               |  (Ryzen / Xeon, 64-128 GB RAM, ZFS Mirror) |
               +---------------------+----------------------+
                                     |
    +--------------------------------v--------------------------------+
    |                 Proxmox VE Hypervisor (KVM + ZFS)               |

What Is Included

  • Virtual Gateway & Edge Security (MikroTik CHR / OPNsense):

    • Full-featured router and stateful firewall deployed in a dedicated virtual machine.
    • VLAN network segmentation: office workstations, server tier, VoIP telephony, and isolated guest Wi-Fi.
    • Quality of Service (QoS) prioritizing database traffic and voice communications under peak bandwidth usage.
    • Perimeter protection against port scanning, brute-force attempts, and SYN floods.
  • Universal Multi-VPN for Remote Access:

    • Native L2TP/IPsec and SSTP for instant remote access from standard Windows, macOS, and iOS clients without third-party software.
    • Blazing-fast WireGuard for laptops and smartphones with minimal battery drain.
    • Zero direct RDP ports exposed: access to servers and workstations strictly inside the encrypted VPN perimeter.
  • Client-Server Database Engine (PostgreSQL / Linux):

    • Migration from unstable file-based databases to a resilient client-server architecture on Linux and PostgreSQL / Postgres Pro.
    • Hosted on a redundant ZFS Mirror pool of NVMe SSDs for rapid report generation and transaction processing.
    • Connection options via thin clients, secured web portals, or RemoteApp delivery.
  • Corporate VoIP Telephony (Asterisk / FreePBX):

    • Local IP PBX without per-seat or per-extension recurring subscription costs.
    • Connection of local, mobile, and toll-free SIP trunks from any telecom provider.
    • Multi-level IVR menus, call queues, call recording, and intelligent call forwarding to mobile phones.
  • Self-Hosted Business Services (Docker / LXC):

    • Nextcloud: Private corporate cloud file synchronization with granular permissions and mobile clients.
    • Vaultwarden: Encrypted enterprise password management (Bitwarden API).
    • Uptime Kuma: Internal uptime dashboard tracking external links, servers, and internal applications with instant alerts.
    • Paperless-ngx: Digital document archive with optical character recognition (OCR) and full-text search across scans.
  • Automated 3-2-1 Disaster Recovery (Proxmox Backup Server):

    • Incremental virtual machine backups with block-level deduplication.
    • Point-in-time snapshots before updates, enabling single-click rollback within seconds.
    • 3-2-1 Rule: Live data on ZFS mirror -> local backups on dedicated storage/NAS -> encrypted offsite cloud synchronization (S3 / WebDAV).

Business Financial Impact

Evaluation Metric Legacy Ad-Hoc Setup Noxet All-in-One Solution
OS & Hypervisor Licensing Expensive Windows Server / CAL fees $0 (Proxmox VE, Linux, KVM)
Cloud Software Subscriptions Recurring monthly per-seat fees $0 (Owned high-speed server)
Cloud PBX for 15 Extensions Recurring per-line monthly charges $0 (Local Asterisk engine)
Corporate Cloud Storage Monthly storage tier costs $0 (Internal Nextcloud)
Data Corruption Safeguards High risk of file-lock corruption 100% Resilient (ZFS + PostgreSQL)
Hardware Payback Period — 3–6 Months

Implementation Methodology

  1. Workload Analysis & Hardware Sizing (Day 1): Database size calculation, concurrent user auditing, and selecting the optimal server platform (new hardware or certified enterprise chassis).
  2. Lab Assembly & Pre-Configuration (Days 1–2): Installing Proxmox VE, configuring virtual networking, tuning VMs, Asterisk trunks, and backup jobs in our deployment facility.
  3. Zero-Downtime Office Launch (1 Weekend Day): Database and file migration, endpoint provisioning, and user VPN validation. On Monday, the office operates on the new platform without disruption.
