Proxmox VE is an open-source platform for server virtualization and container management. It combines KVM-based virtual machines with LXC containers and provides a web-based management interface. Proxmox is the leading open-source alternative to VMware vSphere.
Proxmox VE 9.1 (November 2025) is the current version, based on Debian 13 "Trixie" and Linux Kernel 6.17. It brings OCI containers in LXC, TPM state in qcow2, HA Rules, SDN Fabric support and thick-LVM snapshots. PVE 8 reaches end of life in August 2026 - an upgrade to PVE 9 should be completed by summer 2026 at the latest. More in our Upgrade Guide.
Proxmox VE is free to use - there are no license fees. Optional enterprise subscriptions with prioritized support are available but not required for production use. Total costs consist primarily of hardware and optionally our managed service.
Since Broadcom's acquisition of VMware, license costs have increased significantly (often 60-80%). Proxmox offers comparable enterprise features (HA, live migration, Ceph storage) without license costs. Switching is especially worthwhile when VMware contracts are expiring. Learn more on our VMware migration page.
Yes. Proxmox VE supports high availability with automatic failover. If a cluster node fails, VMs are automatically started on another node. The requirement is a cluster with at least 3 nodes and shared storage (Ceph, NFS, or iSCSI). PVE 9 introduces more flexible HA Rules instead of the previous HA Groups.
Proxmox supports local storage (ZFS, LVM, ext4), network storage (NFS, iSCSI, Ceph, GlusterFS), and object storage. For HA clusters, we recommend Ceph (integrated in Proxmox) or an external SAN. The choice depends on your performance and redundancy requirements.
PBS is the specialized backup solution for Proxmox VE. It provides incremental, deduplicated and client-side encrypted backups. Since PBS 4.2 (May 2026), S3 object storage is officially stable - backups can be stored on Hetzner Object Storage, MinIO, AWS S3 or Wasabi. More on our PBS page.
We offer three service levels: Standard (Mon-Fri 8am-5pm, response <8h), Professional (Mon-Sun 7am-5pm, response <3h), Enterprise (Mon-Sun 7am-5pm, response <1h). All include 24/7 monitoring, automated updates, backup oversight and 99.9% uptime SLA. Details on our maintenance page.
Yes. We offer training for administrators - from basic concepts to cluster management and Ceph administration. Training can be conducted remotely or on-site.
We first analyze your existing VMware environment (VMs, network, storage), create a migration plan and execute the migration with minimal downtime. Storage conversion (VMDK → qcow2/ZFS), network reconfiguration and cluster setup are handled by us.

No risk: worst case, you leave with a clearer understanding of your project than before.
“WZ-IT's advice on our Azure migration was technically sound and completely non-binding right from the intro call - we took away a great deal.”

“With Timo and Robin, you're not only on the safe side technically - you also get the best human support! Whether it's quick help in everyday life or complex IT solutions: the guys from WZ-IT think along with you, act quickly and speak a language you understand. The collaboration is uncomplicated, reliable and always on an equal footing. That makes IT fun - and above all: it works! Big thank you to the team! (translated)”

“I recently worked with Timo and the WZ-IT team, and honestly, it turned out to be one of the best tech decisions I have made for my business. Right from the start, Timo took the time to walk me through every step in a simple and calm way. No matter how many questions I had, he never rushed me. The results speak for themselves. With WZ-IT, we reduced our monthly expenses from $1,300 down to $250. This was a huge win for us.”

“WZ-IT manages our Proxmox cluster reliably and professionally. The team handles continuous monitoring and regular updates for us and responds very quickly to any issues or inquiries. They also configure new nodes, systems, and applications that we need to add to our cluster. With WZ-IT's proactive support, our cluster and the business-critical applications running on it remain stable, and high availability is consistently ensured. We value the professional collaboration and the noticeable relief it brings to our daily operations.”

“WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.”

“We have had very good experiences with Mr. Wevelsiep and WZ-IT. The consultation was professional, clearly understandable, and at fair prices. The team not only implemented our requirements but also thought along and proactively. Instead of just processing individual tasks, they provided us with well-founded explanations that strengthened our own understanding. WZ-IT took a lot of pressure off us with their structured approach - that was exactly what we needed and is the reason why we keep coming back. (translated)”

“Timo and Robin from WZ-IT set up a RocketChat server for us - and I couldn't be more satisfied! From the initial consultation to the final implementation, everything was absolutely professional, efficient, and to my complete satisfaction. I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands. I can recommend WZ-IT without reservation and look forward to continuing our collaboration! (translated)”
