whitesky vs Proxmox

In short

Both whitesky and Proxmox provide open-source based virtualization, but they differ significantly in operational model and support. whitesky is designed for organizations that want the flexibility of modern cloud infrastructure without the burden of managing DIY open-source systems.

Overview

Proxmox VE is an open-source virtualization platform combining KVM-based VMs and LXC containers in a single interface. It has gained popularity for its zero-cost licensing and flexibility. However, organizations often find that running Proxmox at scale requires significant operational expertise and investment in internal tooling.

whitesky builds on similar open-source foundations while adding enterprise features, managed operations, and federation capabilities that make it practical for MSPs and organizations that prefer to focus on their business rather than infrastructure.

When to choose whitesky

Consider whitesky if:

  1. You lack infrastructure expertise - managed service handles operations
  2. You need multi-tenancy - built-in customer isolation and billing
  3. You want predictable costs - fixed service fee vs. staff + tools
  4. You need federation - connect across locations and partners
  5. You serve customers - white-label portal and self-service for end users
  6. You prefer not to DIY - no manual updates, patching, or troubleshooting

When Proxmox may still fit

Proxmox may remain appropriate if:

  1. You have strong Linux expertise - comfortable with CLI and DIY management
  2. Budget is the primary constraint - open-source software with internal team
  3. Single small deployment - one or two nodes, limited scale
  4. You want full control - no vendor dependencies whatsoever
  5. You’re comfortable with tooling - able to build your own monitoring and backup

Moving from Proxmox to whitesky is straightforward:

  1. Assessment - whitesky evaluates your current environment and workloads
  2. Planning - identify VMs to migrate and resource requirements
  3. Export - export VMs from Proxmox using standard formats
  4. Import - import into whitesky cloudspaces
  5. Cutover - DNS updates and validation
