Proxmox – Enterprise Virtualization with Openness and Control
Modern IT infrastructures must be stable, scalable, and cost-effective to operate. Many medium-sized businesses face the challenge of strategically evolving their virtualization platform—with a focus on predictability, technological openness, and long-term investment security.
Proxmox offers a fully integrated, open-source-based platform for enterprise virtualization that can scale from a single host to distributed data center structures. SPIRIT/21 provides comprehensive support to companies throughout this process—from strategic and technical evaluation, through architecture design and migration, to the stable operation of productive Proxmox environments. The revision incorporates the technical comments from the agreed-upon draft, particularly regarding the integration of Ceph/HCI and the integrated backup function in conjunction with Proxmox VE.
What is Proxmox Virtual Environment?
Proxmox Virtual Environment is a comprehensive open-source platform for enterprise-grade server virtualization. It combines the KVM hypervisor for virtual machines and Linux Containers (LXC) on a single management platform and integrates key features for high availability, storage, networking, and data protection.
Proxmox is designed to scale incrementally—from a single virtualization host through cluster setups to distributed, multi-site environments. The Proxmox Datacenter Manager provides a centralized overview and control of multiple Proxmox instances across clusters and locations.
Key Features
- Unified Virtualization: Run virtual machines (KVM) and Linux containers (LXC) on a single platform.
- Clustering and High Availability (HA): Integrated clustering capabilities with live migration and automatic failover for resilient, low-downtime operation.
- Hyper-Converged Infrastructure (HCI): Hyper-converged setups are possible with Ceph as the storage backend. This allows compute and storage resources to be efficiently operated on the same platform.
- Flexible Storage Stack: Support for ZFS, LVM-Thin, classic shared storage connections such as NFS or iSCSI/FC-SAN, as well as software-defined storage with Ceph.
- Centralized Web Interface: Unified, web-based management of hosts, clusters, virtual machines, containers, storage, and network resources.
- Software-Defined Networking and Integrated Firewall: Network virtualization including VLAN, SDN, and firewall functions directly at the platform level.
- Integrated Backup and Recovery: In conjunction with Proxmox Backup Server, Proxmox VE enables incremental backups, deduplication, fast recovery, and centralized management of backup and restore processes - directly from within the Proxmox environment, not as an isolated standalone backup solution.
Integrated Data Backup with Proxmox Backup Server
Data backup is an integral part of the Proxmox concept for production environments. Proxmox Backup Server is seamlessly integrated into Proxmox Virtual Environment and was specifically designed to back up Proxmox workloads.
- Incremental, deduplicated backups of virtual machines and containers
- Fast recovery of entire systems, individual VMs, or defined data objects
- Storage-efficient and high-performance backup through deduplication and compression
- Additional protection mechanisms through encryption and granular access control
- Centralized management via the web interface with direct integration into Proxmox Virtual Environment
Proxmox thus supports a consistent backup and recovery strategy without the need for additional, separate third-party backup software.
Why Proxmox?
For businesses with professional requirements in terms of operations, scalability, and cost control, Proxmox offers clear strategic advantages: predictable operating costs through subscriptions, technological openness thanks to open source, long-term independence from proprietary licensing models, and enterprise-grade functionality without unnecessary complexity or tight vendor lock-in.
