The short version
- Only Microsoft Azure has a free tier, so it costs nothing to try first.
- Each has a real cost: Proxmox VE per-socket licensing model: cost scales with CPU socket count, not vCore count, resulting in high costs for multi-socket servers; 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

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