clouditiv vs. Proxmox: Which VMware alternative fits enterprise IT?

Proxmox VE is the right choice when you need a lean KVM hypervisor cluster, your workloads run entirely on-premise, and your team is comfortable managing VMs directly. The interface is straightforward, the community is large, and for strictly KVM-centric scenarios Proxmox is often quicker to stand up than OpenStack.

clouditiv addresses the next layer of complexity: if your organisation wants to exit VMware without landing in the next vendor lock-in, if you need to manage public clouds (AWS, Azure, GCP) alongside your private cloud from a single dashboard, or if regulatory requirements (GDPR, KRITIS, ISO 27001) demand a verifiable German operations footprint — OpenStack on clouditiv is the more scalable path. Automation brings a fresh OpenStack cluster live in typically under 60 minutes; day-two operations such as patching, scaling, and backup can be handed over as a managed service.

In short: Proxmox for self-managed KVM without multi-cloud ambitions. clouditiv for structured VMware exit, multi-cloud governance, and a managed enterprise cloud from Germany.

Proxmox offers a free community edition plus commercial subscriptions (from ~€100/node/year for standard support). The real cost is operational: setup, network configuration, backup strategy, and day-two work sit entirely with your team.

clouditiv publishes per-socket pricing from €149/socket/month — including automated deployment, updates, and optional 24/7 managed operations. For organisations migrating off VMware, our free assessment typically models 50–70 % savings vs. current Broadcom licensing volume. When you factor in staff time for manual Proxmox administration versus the clouditiv managed service, the economics often tip in clouditiv's favour at 3–5 nodes or more.

Our TCO calculator shows the side-by-side view based on your specific node count, VMware licence costs, and headcount — free and without sales pressure.

A Proxmox-to-OpenStack migration is not a big-bang cutover. clouditiv manages the transition in defined waves: the OpenStack infrastructure is built and validated in parallel first. Workloads are then prioritised — non-critical systems first, production VMs after a test phase. Proxmox is decommissioned incrementally.

Practically: VMs typically reside as QCOW2 or RAW images, which simplifies import into OpenStack Glance. Network configurations are mapped to Neutron/OVN. Typical migration horizon: 4–8 weeks for mid-size environments (20–200 VMs), depending on the number and complexity of network zones.

clouditiv handles assessment, migration plan, technical execution, and handover with documentation. Optionally, we stay on as a managed-operations partner for ongoing operations.
