The best way to host a cloud platform is on bare metal servers, not on a VPS.
Recommended setup
Bare metal servers → Hypervisor/cloud software → VMs/containers → users/apps
Why bare metal is best
- Full control over hardware
- Better performance
- Supports nested virtualization properly
- More reliable networking and storage
- Better for production workloads
- Easier to sell VPS/cloud services from it
Good cloud platform options
For learning or small private cloud:
- Proxmox VE
- OpenStack
- Apache CloudStack
- Kubernetes for container-based cloud apps
For production:
- Multiple bare metal servers
- Redundant storage
- Dedicated networking
- Backup system
- Monitoring
- Firewall/security setup
- Cloud management software like OpenStack, CloudStack, or Proxmox
Simple recommendation
Use:
Bare metal server + Proxmox if you want an easier private cloud.
Use:
Multiple bare metal servers + OpenStack/CloudStack if you want a larger cloud platform like a real cloud provider.
A VPS is okay only for learning or testing, not for serious cloud hosting.
