The Challenge

Proprietary hypervisor licensing is placing unsustainable pressure on IT budgets

Following significant changes to VMware's licensing model since its acquisition by Broadcom, many organisations are facing dramatically higher costs for virtualisation infrastructure they have relied upon for years — with limited time to evaluate and migrate to alternatives.

Escalating hypervisor licensing costs

Per-socket or per-core enterprise licensing fees for commercial hypervisors represent a significant and recurring operational expenditure, particularly for organisations running large virtual machine estates.

Vendor dependency and feature gating

Proprietary platforms restrict access to advanced features — high availability, live migration, backup integration — behind additional licensing tiers, creating ongoing budget uncertainty and operational constraints.

Complex migration paths and skills gaps

Evaluating and migrating to an alternative virtualisation platform while maintaining production uptime requires expertise that many in-house IT teams do not have available internally.

Our Solution

Proxmox VE — enterprise virtualisation without the enterprise licensing cost

Proxmox Virtual Environment is a mature, open-source virtualisation management platform built on Debian Linux. It integrates KVM hypervisor for full virtual machines and LXC for lightweight containers — both managed through a unified web-based interface — providing genuine enterprise capabilities at a fraction of the cost of proprietary alternatives.

Supplied and deployed by Cleantech IT SolutionsOur team manages the end-to-end Proxmox engagement — from hardware specification and cluster architecture through to VM migration, high availability configuration and ongoing platform support — ensuring a controlled and low-risk transition.

Proxmox VE supports clustering across multiple nodes with built-in high availability, live VM migration, integrated backup via Proxmox Backup Server, software-defined networking and storage — all included in the base platform without additional licensing fees.

Optional Proxmox enterprise subscriptions provide access to the stable enterprise repository and professional support channels. Cleantech IT Solutions can supply and manage these subscriptions as part of a comprehensive managed services engagement.

KVM + LXC Unified Platform

Key Capabilities

What Proxmox VE delivers for your organisation

KVM Virtual Machines & LXC Containers

Proxmox VE runs both full KVM virtual machines and lightweight LXC Linux containers from a single management interface — supporting Windows, Linux and FreeBSD guests with live migration between cluster nodes.

Built-In High Availability

Proxmox Cluster File System (pmxcfs) and the HA Manager enable automatic VM failover across cluster nodes in the event of a host failure — maintaining service continuity without manual intervention or additional licensing.

Proxmox Backup Server Integration

Proxmox Backup Server provides incremental, deduplicated backups of virtual machines and containers — with fast restore, encryption and tape support — all managed through the same Proxmox interface at no additional cost.

Software-Defined Networking

Proxmox VE includes a software-defined networking layer supporting VLANs, bridges, bonds and Open vSwitch — providing flexible network segmentation and isolation for multi-tenant and security-sensitive workloads.

Flexible Storage Backend Support

Proxmox VE integrates natively with a wide range of storage backends including local disks, LVM, ZFS, Ceph RBD, NFS, iSCSI and Ceph Object Storage — enabling flexible storage architecture without proprietary storage appliances.

Significant Licensing Cost Reduction

Organisations migrating from VMware or Hyper-V to Proxmox VE routinely achieve substantial reductions in virtualisation platform costs — with optional enterprise subscriptions available at a fraction of commercial hypervisor pricing.

How We Work

A structured migration to Proxmox VE

Migrating from a proprietary hypervisor requires careful planning. Our five-phase methodology minimises risk and ensures business continuity throughout the transition.

Current State Assessment

Inventory of existing VMs, resource utilisation, storage dependencies and network topology to inform migration planning and hardware requirements.

Cluster Design & Procurement

Proxmox cluster architecture design, hardware specification and procurement — including servers, shared storage and networking appropriate to your workload profile.

Platform Deployment

Physical installation, Proxmox VE cluster bootstrapping, HA configuration, backup server deployment, storage integration and network configuration.

VM Migration & Validation

Controlled migration of virtual machines from the existing platform, workload validation, performance testing and application owner sign-off prior to decommissioning legacy infrastructure.

Managed Operations & Support

Ongoing platform monitoring, patch management, capacity planning, incident response and platform upgrades under a managed services agreement.
