A VPS is a slice of a physical server with its own operating system, CPU cores and RAM. A dedicated server is the whole physical machine. Start on a VPS unless you already know you need the hardware, and move to dedicated when you hit the limits a VPS can’t fix by upgrading.
That’s the rule we give customers. The rest of this post is how to tell which side of it you’re on.
What each one really is
A virtual private server runs as a virtual machine on a host that other customers share. You get root access, your own OS and your own allocation of resources, but the physical CPU, disks and network card are shared with the other VMs on the box. How well a provider isolates those VMs is most of what separates a good VPS from a bad one.
A dedicated server has no one else on it. Every core, every gigabyte of RAM and every drive is yours, so the performance you measure on a quiet Sunday is the performance you get on a busy Monday.
Here’s how our two options compare on today’s price list:
| VPS | Dedicated server | |
|---|---|---|
| Starting price | $8/month | $126/month |
| CPU | Dedicated vCPU cores | The whole machine |
| Bandwidth | 5 TB/month | 30 TB+ |
| Out-of-band access | — | IPMI, private network |
| Locations | Chicago, Ashburn, LA | Chicago, Ashburn, LA |
Our virtual private servers come with dedicated vCPU, guaranteed RAM, SSD storage and full root access, from $8 a month up to 10 cores and 10 GB of RAM on the Business plan at $35. Our dedicated servers start at $126 a month, and every plan includes at least 30 TB of bandwidth.
What’s a “virtual dedicated server”?
A virtual dedicated server (VDS) is a VPS with CPU cores and RAM reserved for you instead of drawn from a shared pool. No standard defines it. It’s a marketing label, and two hosts can mean quite different things by it.
The idea behind it is sound. On a cheap VPS, the host often sells more vCPUs than the machine has physical cores, betting that not every customer gets busy at once. A VDS promises your cores stay yours, so someone else’s busy hour shouldn’t show up as CPU steal on your VM.
It still isn’t a dedicated server. Your VM sits on a hypervisor next to other customers’ VMs and shares the disks, the network card and the uplink with them. You can’t pick the CPU model or the RAID layout, and there’s no IPMI console when the OS won’t boot. Reserved cores fix CPU contention. They do nothing for a database that’s starved for disk I/O.
When a host says “VDS”, ask:
- Is each vCPU a full physical core or a hyperthread?
- Is the RAM guaranteed, or can the host overcommit it?
- Is storage local NVMe or network storage, and is disk I/O capped?
- What does steal time look like under load? Measure it yourself with the checks further down.
Every one of our VPS plans comes with dedicated vCPU and guaranteed RAM, which covers what most hosts sell as virtual dedicated server hosting. We just call it a VPS. If what you actually need is the disks and the network card to yourself, the VDS label won’t get you there, and a dedicated server is the honest answer.
Why a VPS is the right place to start
It’s cheap to be wrong. At $8 to $35 a month, you can find out what your application actually needs before you commit to hardware.
It scales in place. You can upgrade CPU, RAM or storage without downtime, so a VPS that fits today can grow for a while.
It covers a lot of real work. Business websites, small SaaS apps, dev and staging environments, VPN gateways, CI runners and trading bots all run comfortably on a VPS. Most sites that think they need a dedicated server don’t, yet.
It deploys the way you want. Linux (Ubuntu, Debian, AlmaLinux, Rocky), Windows Server, or your own ISO.
The signs you’ve outgrown a VPS
This is where people wait too long. Watch for these:
- You’re on the top plan and still short. Once the biggest VPS isn’t enough, the next step is hardware, not another upgrade.
- You’re pushing past 5 TB of transfer a month. Dedicated plans start at 30 TB, and our 10 Gbps unmetered servers start at $499 a month.
- Disk-heavy work is erratic. A database that’s fast at night and sluggish at noon is telling you something about shared storage.
- You need to control the hardware. Specific CPUs, lots of RAM, a particular RAID layout, extra drives or a hypervisor of your own all mean a physical machine.
- You need console access when the OS is down. On our dedicated servers, IPMI sits on a private management network by default, so you can reach the console and power controls even when the server won’t boot.
- Compliance or isolation rules say single tenant. Some auditors and customers won’t accept shared hardware at all, however good the isolation is.
If two or more of those are true, it’s time.
How to check before you spend money
Don’t upgrade on a hunch. A week of numbers from the VPS you already have will tell you more than any comparison table, including ours.
- CPU steal. Run
topand look at thestvalue. Steal is time your VM wanted the CPU and the host gave it to someone else. On a VPS with dedicated vCPU it should sit near zero; if it doesn’t, raise a ticket before you do anything else. - I/O wait. The
wavalue in the same view shows how long the CPU sits waiting on disk. If it climbs every time the database gets busy, storage is your ceiling. - Memory pressure. Check
free -mand watch for swap use. A server that swaps under normal load needs more RAM, and a bigger VPS plan may be all it takes. - Transfer. Look at your monthly bandwidth graph and compare it with your plan’s allowance, not with last month’s bill.
If the fix is more RAM or another couple of cores, upgrade the VPS. If the fix is “stop sharing the disk,” that’s a dedicated server.
When a dedicated server is overkill
A dedicated server that sits mostly idle is money on fire. If your workload fits comfortably on a mid-size VPS, keep it there and spend the difference on backups and monitoring.
The other trap is buying dedicated for reliability alone. A single dedicated server is still a single server. Both products carry our network uptime SLA, and our hardware replacement SLA covers VPS and dedicated servers alike. If downtime would really hurt, two servers and a tested failover beat one bigger one.
What changes when you move to dedicated
You get more to own. There’s no hypervisor between you and the hardware, which is the point, but it also means you pick the OS, the partitioning and the RAID layout at order time. In-stock servers are online the same or next day, and custom builds are ready in a week or less.
You can also turn the machine into your own small cloud. Server virtualization is included at no extra cost, so Proxmox VE, VMware or Hyper-V on a dedicated server gives you VPS-style flexibility on hardware nobody else touches. That’s the right move when you’re running several VPSes that are all busy all month.
If you don’t want to run the OS layer yourself, add Enterprise Server Management: $99 a month per server, or $79 with a qualifying cPanel license. It covers OS patching, advanced monitoring and troubleshooting, and moves you to the faster SLA tier: 99.95% network availability, 1-hour hardware replacement and a 15-minute support response.
Windows works on both. On a dedicated server, Windows Server 2016 through 2025 is available: 2016 and 2019 are on the order form, and newer versions are available on request. The Standard license is $50 a month.

FAQ
No. A VPS is a virtual machine on shared physical hardware, with its own OS and allocated resources. A dedicated server is the entire physical machine, with nothing else running on it.
No. A virtual dedicated server (VDS) is a VPS with CPU cores and RAM reserved for you, but it still runs as a virtual machine on shared hardware, sharing disks and network with other customers. Our VPS plans include dedicated vCPU and guaranteed RAM on every plan, which is what most hosts mean by VDS.
When you’ve maxed out the top VPS plan, when you regularly need more than 5 TB of transfer a month, when disk performance swings with the time of day, or when you need hardware control or single-tenant isolation. Two or more of those and dedicated is the better buy.
At the same size, it’s more consistent rather than magically faster. The big difference is that nobody else’s workload can slow yours down, and you can buy far more CPU, RAM and bandwidth than any VPS plan offers.
Yes, on both. On dedicated servers, Windows Server 2016 through 2025 is available, with the Standard license at $50 a month; 2016 and 2019 are on the order form and newer versions are on request.
