Proxmox VE · Hosted in Germany
Managed Proxmox Cluster
High-availability Proxmox VE clusters from German data centers: designed, built, and operated around the clock. With HA Manager, live migration, and rolling updates – without you having to look after the platform.
Why Proxmox
Open virtualization without license lock-in.
Proxmox VE is an open virtualization platform built on Linux, KVM, and LXC – mature, actively developed, and running in tens of thousands of production environments. There are no license fees per socket or per VM, no feature paywall for high availability, and no vendor that can change the pricing model overnight.
That is exactly why Proxmox is the first choice as a VMware alternative: clustering, HA, live migration, snapshots, and backup integration are part of the platform – not paid add-on modules. How a switch works is covered under migrating from VMware to Proxmox.
Scope
What your Managed Proxmox Cluster includes.
- 3-node cluster as the standard: true quorum via Corosync, still able to make decisions when one node fails.
- Proxmox HA Manager: when a node fails, virtual machines restart automatically on an available node.
- Live migration: VMs move between nodes during normal operation – maintenance without downtime.
- Rolling updates: updates node by node without a full platform outage, critical patches take priority.
- Redundant storage: Ceph across all nodes or ZFS replication, matched to the load profile.
- Redundant networking: bonding/LACP, separate management and storage networks, firewalling.
- 24/7 monitoring & on-call duty: alerting, escalation chain, managed operations.
- Separate backups with restore tests: because an HA cluster is no substitute for a backup.
Architecture
The 3-node Proxmox cluster in one diagram.
Three nodes are deliberately the standard: they are the minimum for a true quorum. If one node fails, the remaining two form the majority – the cluster stays able to make decisions, and the Proxmox HA Manager automatically restarts the affected virtual machines. How this plays out during an actual outage is shown step by step on the high availability page.
FAQ
Common questions about the Managed Proxmox Cluster.
How many nodes does a Proxmox cluster need?
For true high availability, at least three – only then is there still a majority (quorum) when one node fails. Two-node setups are possible with an external quorum device; for business-critical applications we recommend three or more nodes.
Is Proxmox ready for production use?
Yes. Proxmox VE is based on Debian, KVM, and LXC – technologies that have been running in production for decades – and is actively developed. Clustering, HA, live migration, and backup integration are core parts of the platform.
Can existing virtual machines be taken over?
Yes. VMs from KVM-based environments move over directly; VMware systems are converted as part of the migration. Live where possible, otherwise with a short, plannable cutover window.
Do you also operate existing Proxmox clusters?
Yes. After an audit we connect your cluster to our monitoring and take over operations, updates, and on-call duty – as it is, or with a step-by-step rebuild toward the target architecture.
What does a Managed Proxmox Cluster cost?
Managed clusters start at €399.99 net per month (Essentials: 3 nodes with Ceph HA storage, fully managed). The Business package with 6 nodes across 2 locations, SLA reports, and monitoring costs €1,099.99 net; Enterprise setups are quoted individually. All prices at Pricing – or call us: +49 9382 2209100.
