TL;DR
Instant Metal is Synteq's single-tenant KVM virtual machine on dedicated hardware, with dedicated cores, RAM, and NVMe. No noisy neighbors, no CPU steal, and deployment in seconds like a cloud instance. Bare metal is a full physical server with no virtualization layer: maximum hardware control, but you provision, tune, and maintain it yourself. Both are single-tenant; the difference is the operating model. Instant Metal behaves like cloud: fail over to it, resize it to a larger instance, and never touch a network card or a RAID array. Bare metal behaves like owning a server.
Once you've outgrown smaller VM instances, the next decision is less about how much hardware, and more about how much of the operations you want to own. That's the line Instant Metal and bare metal sit on. Both give you dedicated, single-tenant resources. What differs is everything around them. This breaks down what each one is and which one fits your workload.
What is Instant Metal?
Instant Metal is a single-tenant virtual machine running on dedicated hardware. The underlying physical server is yours alone, with dedicated cores, RAM, and NVMe, so there are no noisy neighbors and no CPU steal. What you provision is what you get, consistently.
The difference from a traditional dedicated server is the delivery model. Instant Metal is a KVM instance, which means it inherits the cloud operating model: it deploys in seconds and supports snapshots, failover, block storage, and resize. You manage it like a cloud instance.
What is bare metal?
Bare metal is a full physical server with no virtualization layer between you and the hardware. You get the entire machine and direct access to all of it: every thread, every network port, every disk.
What you also get is everything involved in running it. Provisioning takes tens of minutes rather than seconds, and that's assuming an install goes off without a hitch. Issues with BIOS settings, PXE boot errors, autoinstallers getting tripped up by uncommon disk configs, etc are common. You're responsible for the operational surface: network interface configuration, throughput tuning, RAID array maintenance, and everything else that sits between "the hardware works" and "the workload runs well."
Where they're the same
Both Instant Metal and bare metal are single-tenant. The resources are dedicated. No shared cores, no CPU steal, no other workload cutting into yours. In both cases you get the full CPU, RAM, and storage you provisioned, with no contention.
That's where the similarity ends. Both give you the same dedicated hardware; what differs is what you do with it and how much of your own time it eats.
The core difference: cloud-like vs. owning a server
Instant Metal inherits the cloud operating model, while bare metal inherits a server in a rack.
Cloud-like means the platform absorbs the operational toil. Deploy, resize, and tear down are all platform operations that take seconds to minutes. With bare metal, the hardware setup and maintenance are yours to do by hand: provisioning, RAID, network configuration, and drivers.
If you've run infrastructure in a public cloud, you already know the Instant Metal workflow. If you've manually installed a box and tuned it by hand, you know the bare metal one. The performance gap between them is negligible for the vast majority of workloads, but the operational gap is not.
Provisioning and spin-up
Instant Metal deploys in seconds, at the same speed as a regular VM, because it is one. That speed matters most when you're standing up more than a single box: a small cluster, a scaled-out tier, a fresh environment. Each instance is identical and arrives with the OS and storage already in place, so there's no manual OS install per box and no RAID to configure.
Bare metal takes longer per box. Tens of minutes from request to ready, because real hardware has to be allocated, brought online, and provisioned by hand. Stand up five at once and that's five separate rounds of OS install and RAID setup before any real work can start. Nobody provisions five servers because they enjoy configuring RAID.
Zero sysadmin overhead
Bare metal is yours to operate, which means a recurring list of work that isn't your actual job:
- configuring and bonding network interface cards
- tuning kernel and driver parameters for throughput
- setting up, monitoring, and rebuilding RAID arrays
- handling drive failures and array degradation
- keeping the hardware layer healthy enough that the workload layer stays stable
Instant Metal skips all of it. The platform owns the hardware and presents you a clean, single-tenant instance, so you spend your time on the workload instead of the box underneath it.
Fail over
On Instant Metal, failover is something the platform does for you. If the underlying hardware fails, your instance is brought back on healthy hardware. You don't open a ticket about a dead drive, and you're not rebuilding a degraded RAID array.
On bare metal, a hardware failure is a physical problem you own. A drive dies in the RAID array and it's on you to swap it and rebuild the array before the box is trustworthy again. Recovery means hands on the machine, or a replacement, and bringing its state back by hand. That's manageable with the right staff, and expensive without.
Resize and migrate
Outgrow an Instant Metal instance and you upsize to a larger one. The platform migrates your workload onto it with your OS, configuration, and data intact, so there's no reinstall and no manual migration. Coming up on the larger size takes a reboot and a few minutes of downtime.
Bare metal can resize too, but it's a scheduled physical job. Adding RAM, swapping in a bigger CPU, or installing more disks means booking a maintenance window and taking the box offline while someone does the work. It's potentially hours of downtime, coordinated in advance, and there's a limit to how far one box can grow before you're migrating to a larger one anyway.
When to pick Instant Metal
Pick Instant Metal when you want dedicated hardware and the cloud operating model at the same time. That fits a broad set of real situations:
- Outgrown a VM: you need more cores, more RAM, or more consistent power than a shared instance gives you, without giving up the convenience of cloud.
- Standing up multiple servers: clusters, scaled-out tiers, or fresh environments, where each system deploys in seconds instead of per-box hardware setup.
- Iterating fast: the ability to quickly deploy and resize let you change your mind without changing hardware.
- Rather deploy workloads than play sysadmin: no manual OS installs, no RAID rebuilds, no NIC bonding.
When bare metal actually wins
For most workloads, Instant Metal is the better answer: the same dedicated, single-tenant resources, with the cloud operating model on top. The case for bare metal is narrow: workloads that can't absorb the 1-2% CPU hit virtualization costs, or hobbyists who want to wring every cycle out of the hardware. If that's you, bare metal earns its place. For everyone else, Instant Metal covers it.
FAQ
Is Instant Metal the same as bare metal?
No. Both are single-tenant with dedicated resources, but Instant Metal runs on a KVM layer and behaves like a cloud instance (seconds to deploy, failover, and resize), while bare metal is a raw physical server with no virtualization layer.
Does Instant Metal use a hypervisor?
Yes. Instant Metal is a single-tenant KVM virtual machine on dedicated hardware, so the underlying host is yours alone.
How fast does Instant Metal deploy?
In seconds. It deploys on the same path as a regular VM, because it is one.
Can I resize an Instant Metal instance to a larger size?
Yes. You upsize to a larger instance and the platform migrates your workload over with your OS, configuration, and data intact. It takes a reboot and a few minutes of downtime.
Why would anyone choose bare metal over Instant Metal?
Only for a workload that can't absorb the 1-2% CPU hit virtualization costs, or for hobbyists who want every cycle the hardware can give. For almost everything else, Instant Metal is the better choice.
Does Instant Metal have noisy neighbors?
No. It's single-tenant: dedicated cores, RAM, and NVMe, no CPU steal.
