Sovereign virtualization with Proxmox / ProxVE
Open platform for virtualization, containers and hyperconvergence to replace VMware, Nutanix and Hyper-V — with high availability, the best TCO on the market and an enterprise subscription provided by OpenTechs.
What Proxmox VE is and why it became the standard
Proxmox Virtual Environment (Proxmox VE) is an open-source, enterprise-grade server virtualization platform that brings together in a single product what traditionally required several expensive, separate solutions: virtual machines (KVM/QEMU), containers (LXC), software-defined storage (Ceph and ZFS), software-defined networking (SDN), firewall, backup and high availability — all in a single, clustered web interface.
In practice, it lets you consolidate dozens or hundreds of physical servers into an efficient cluster, where each workload runs isolated and securely and can be moved between nodes without shutting down. It is the foundation on which modern companies build their private data center — the Software-Defined Data Center (SDDC).
ProxVE is the enterprise edition delivered by OpenTechs: Proxmox VE with a support subscription, a stable enterprise repository, security hardening, orchestration modules and the guidance of the leading reference in open infrastructure in Latin America.
Three-tier or hyperconvergence? Proxmox does both
There is no “right” architecture — only the one suited to your scenario. Proxmox VE supports both the classic three-tier model (reusing your current SAN/NAS storage) and native hyperconvergence with Ceph. OpenTechs helps you choose and size it.
Three-tier architecture
Compute, network and storage are separate physical layers. Servers access central storage (SAN/NAS) over a dedicated network fabric.
Hyperconvergence (HCI)
Compute and storage coexist on the same nodes. Each server contributes CPU, RAM and disk to a distributed pool (Ceph), eliminating central storage and its cost.
When to use each
- Three-tier — when you already have robust SAN/NAS storage and want to leverage it, or you need extreme IOPS with a dedicated array.
- Hyperconvergence (HCI) — when you want simplicity, linear scale (just add nodes), lower cost and the elimination of the single point of failure of central storage.
- Hybrid — Proxmox lets you combine them: HCI for most workloads and SAN for specific cases.
The pillars of a ProxVE cluster
Cluster and High Availability (HA)
Multiple nodes form a cluster with unified management. If a node fails, HA automatically restarts the affected VMs on another healthy node — restoring service in seconds, without manual intervention.
Live / Online Migration
VMs migrate from one node to another while running, with no downtime. This enables hardware maintenance, load balancing and updates without any outage window.
Software-defined storage
With Ceph, the disks of all nodes form a single, replicated and self-healing pool. With ZFS, you get instant snapshots, compression and checksum integrity. Support also for NFS, iSCSI and Proxmox Backup Server.
Security and networking
Distributed per-VM firewall, software-defined networks (SDN), multiple authentication sources (LDAP/AD), role-based access control (RBAC) and built-in backups with retention and immutability.
No per-core license. With real support.
Proxmox VE is open source: there is no license charge per socket, core or VM as with VMware. What you contract is the support subscription — access to the stable enterprise repository and to the vendor’s support. OpenTechs provides the ProxVE subscriptions and handles the entire operation.

Proxmox / ProxVE vs. VMware
| Criterion | VMware (proprietary) | Proxmox / ProxVE |
|---|---|---|
| License model | Per-core, annual, rising | Open source + subscription |
| Total cost (TCO) | High and unpredictable | Best TCO on the market |
| Vendor lock-in | High | None — heterogeneous hardware |
| Hyperconvergence | vSAN (separate license) | Native Ceph, included |
| Containers | Limited | Native LXC |
| Auditable code | No | Yes, open source |
| Data sovereignty | Vendor-dependent | Full, on your infrastructure |
| Local support | Limited | 24x7x365 OpenTechs |
Where ProxVE delivers value
Data center consolidation
Reduce dozens of physical servers to an efficient cluster, with greater density and lower power and space costs.
Leaving VMware
Planned migration from VMware/Nutanix/Hyper-V to Proxmox, with a controlled window and zero data loss.
High availability
Critical services with automatic failover and storage replication — with no single point of failure.
Private cloud / HCI
Hyperconverged private cloud with Ceph, scalable node by node, for workloads that need to grow.
VDI and labs
Virtual workstations and test environments provisioned on demand, isolated and disposable.
Edge and branches
Compact clusters at branch offices, centrally managed, running the same stack as the data center.
What changes for leadership
- Lower CAPEX and OPEX — no more per-core licensing; reuse of existing hardware.
- Budget predictability — a stable subscription, with no renewal surprises.
- Sovereignty and compliance — data on your infrastructure, under your jurisdiction.
- Business continuity — HA, replication and DR reduce the risk of downtime.
- Strategic independence — no lock-in to a foreign vendor.
- Skilled team — official training with certification included.
