The short version

  • Only Microsoft Azure has a free tier, so it costs nothing to try first.
  • Each has a real cost: Microsoft Azure the 12 months of free services is available only to new customers who have not previously had an Azure account or received 12 months of free services; Proxmox VE per-socket licensing model: cost scales with CPU socket count, not vCore count, resulting in high costs for multi-socket servers

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Microsoft Azure

  • The 12 months of free services is available only to new customers who have not previously had an Azure account or received 12 months of free services
  • The 12 months free offer is not available to customers who sign up directly for pay as you go in China and India
  • Customers who try Azure free must move to pay as you go within 30 days to keep receiving the 12 months of free services
  • Free services are capped at specified monthly amounts, and only some of them are always free

Proxmox VE

  • Per-socket licensing model: cost scales with CPU socket count, not vCore count, resulting in high costs for multi-socket servers
  • Linux-based host only; Windows hypervisors not supported, limiting adoption in Windows-focused organisations
  • Clustering and high-availability setup requires operational expertise and careful network configuration
  • Commercial support tiers limit advanced features (just-in-time access, network flow logs) to paid subscriptions
  • Smaller ecosystem of third-party plugins and integrations compared to VMware vSphere
