Bare Metal Server
Bare Metal Server is a physical server provisioned for exclusive use by a single tenant, without a shared hypervisor or neighboring virtual machines competing for resources; Bare metal providers (Hetzner, OVHcloud, Equinix Metal, Cherry Servers) maintain pools of physical servers that are provisioned to customers on demand or by reservation; For builders running a homelab in the cloud (full Proxmox or nested virtualization setups) or computationally heavy workloads like on-premise AI inference, bare metal is the correct choice
Bare Metal Server is a physical server provisioned for exclusive use by a single tenant, without a shared hypervisor or neighboring virtual machines competing for resources. The operating system runs directly on the hardware, eliminating the CPU and I/O overhead introduced by virtualization. Bare metal is chosen when workloads require predictable, high-throughput I/O (databases, video transcoding, ML training), when consistent CPU performance is required (latency-sensitive trading or real-time processing), or when the tenant needs to run their own hypervisor for a private cloud.
How it works
Bare metal providers (Hetzner, OVHcloud, Equinix Metal, Cherry Servers) maintain pools of physical servers that are provisioned to customers on demand or by reservation. Provisioning involves installing a chosen OS via a network boot environment (PXE) controlled through the provider’s management interface (IPMI/iDRAC). The customer receives full root access and administrative control, including hardware-level access through IPMI for out-of-band management, RAID configuration, and BMC firmware updates.
Key facts
- Performance advantage: Bare metal can deliver 20 to 40 percent higher disk IOPS than equivalent VPS due to the absence of hypervisor storage abstraction
- Cost: Entry dedicated servers from Hetzner Auction (refurbished hardware) start around $30 to $50/month, offering substantially more raw resources than equivalent VPS pricing
- Provisioning time: Bare metal provisioning takes minutes to hours compared to seconds for VPS; not suitable for autoscaling workflows
For builders
For builders running a homelab in the cloud (full Proxmox or nested virtualization setups) or computationally heavy workloads like on-premise AI inference, bare metal is the correct choice. The Hetzner server auction (auction.hetzner.com) offers refurbished enterprise hardware at significant discounts and is a popular entry point for builders who want dedicated resources without enterprise pricing.
