VPS vs dedicated server
Answer
Choose a VPS until you need predictable tail latency, more than 64 GB of RAM, or hardware-level control. A modern VPS on EPYC with NVMe matches bare metal for most workloads. Bare metal wins on p99 consistency, disk throughput and physical isolation.
The gap narrowed a lot
A decade ago virtualisation cost you a visible chunk of performance. Today, with hardware-assisted virtualisation, SR-IOV networking and NVMe passthrough, a well-provisioned KVM guest runs within a few percent of the metal for most workloads. The reason to buy bare metal is rarely raw throughput any more.
What virtualisation still costs you is consistency. Your average is fine; your p99 is at the mercy of what the other guests are doing. For a batch job nobody notices. For a database serving synchronous queries, or a validator whose rewards depend on propagation timing, that variance is the whole problem.
Choose a VPS when
You need under 64 GB of RAM. Your workload tolerates occasional latency variance. You want to resize without migrating. You want snapshots and rebuilds in seconds. You are running fewer than a dozen containers. You want to start at $4 and find out what you actually need.
That covers the large majority of real workloads, including plenty that people buy bare metal for out of habit.
Choose bare metal when
You need predictable p99. You need more than 64 GB of RAM or more than 16 cores. You are running your own hypervisor, which nesting makes awkward. You need sustained disk throughput above what a shared NVMe pool will guarantee. You want LUKS with no hypervisor in the trust model. Or you need specific hardware — a GPU, a particular NIC, a TPM.
The pricing crossover is around the CITADEL tier. Once a VPS costs $52 a month, a dedicated OUTPOST at $46 with an entire machine behind it is worth a serious look.

A third option people forget
Several small VPSs across different jurisdictions often beat one large server. Failure domains are separate, legal exposure is spread, and you can lose an entire country without losing the service.
Three VECTOR instances at $14 each in Bulgaria, Iceland and Panama cost less than one RAMPART and are far harder to take down in a single event. For anything that needs to stay up, that geometry is usually the right one.
Frequently asked questions
01 Is a VPS slower than a dedicated server?
On average, barely — a few percent on modern hardware. On tail latency, meaningfully: your p99 depends on what other guests are doing. That distinction decides most real choices.
02 When does bare metal become cheaper?
Around $50/month. Once a VPS costs that, an entry dedicated server at $46 with the whole machine behind it is worth comparing directly.
03 Can I run Docker on a VPS?
Yes — full KVM virtualisation means your own kernel, so Docker, Podman and Kubernetes all run normally. Nested virtualisation is available on request if you need VMs inside your VM.
