Linux vs Windows VPS: How to Actually Choose in 2026

For most web workloads, Linux is the correct default. If you are building a website, an API, a WordPress install, a Node or Python app, a game server or a container host, pick a Linux VPS and stop reading comparison articles.

Only three things should ever flip that decision. One: your application genuinely requires the Windows stack, and after reading the .NET section below you may find yours does not. Two: the Windows Server licence, which is a real recurring cost your provider either bundles or asks you to bring. Three: RAM and disk overhead, because Windows Server needs a materially bigger baseline than a minimal Linux install, which means you need a bigger plan for the same application.

Everything else you will read about this choice, including performance folklore and "Windows is easier because it has a desktop", is noise. Here is the version with the numbers in it.

Key Takeaways

• Linux is the default. Windows is an exception you should be able to name in one sentence, such as "our app is ASP.NET Framework 4.8 and uses Windows Authentication".
• Modern .NET (formerly .NET Core) is cross-platform and fully supported on Linux. Being a .NET shop is no longer a Windows requirement on its own.
• SQL Server has run on Linux since SQL Server 2017. That removes another commonly assumed Windows dependency.
• Windows Server is licensed per core with Client Access Licences on top. Hosting providers usually resell it monthly through Microsoft's SPLA program, so it appears as a recurring line item, not a one-off.
• Microsoft's own minimums for Windows Server 2025 are 2 GB RAM and 32 GB of system partition disk. A 1 GB / 25 GB Linux-sized plan is not a Windows plan.
• RDP is a far bigger attack surface than SSH and is brute-forced constantly. Microsoft's own guidance is to not expose it directly to the internet.

The Three-Question Test

Work down this list. The first "yes" decides it.

1. Does your application only run on Windows? Not "was written by a Windows team", not "we use Visual Studio". Does the binary or framework refuse to run anywhere else? If yes, you need Windows. Go read the licensing and RDP sections.
2. Does a hard dependency only exist on Windows? Classic ASP, ASP.NET Framework (not modern .NET), a Microsoft Access database file, MS Exchange, an ActiveX or COM component, a vendor-supplied accounting or trading executable, Windows Authentication against Active Directory. If yes, Windows.
3. Is anything left? If you got here, choose Linux. It costs less, uses less RAM for the same job, and has better tooling for everything you are about to do.

Notice what is not on that list: your own comfort level. That matters, but it is a training question, not an architecture question, and it is much cheaper to learn a few Linux commands than to pay for a Windows licence every month for five years.

Decision Table: Workload to Operating System

Workload	Recommended OS	Why
WordPress, WooCommerce, Joomla, Drupal	Linux	PHP and MySQL are native here. Every tutorial, control panel and caching stack assumes Linux.
Node.js, Python, Ruby, Go, Rust apps	Linux	Primary development target for all of them. Deployment tooling, process managers and containers are Linux-first.
Modern .NET 8 / 9 / 10 web app (ASP.NET Core)	Linux	Fully supported and commonly deployed on Linux behind Nginx. No licence cost.
ASP.NET Framework 4.x, Classic ASP, WebForms	Windows	.NET Framework is Windows-only. This is the single most common legitimate reason to buy Windows.
SQL Server database	Either	SQL Server runs on RHEL and Ubuntu from version 2017 onward. Choose based on the app in front of it, not the database.
MS Access backend, Crystal Reports, COM or ActiveX components	Windows	These have no working Linux equivalent. Do not try to force it.
Vendor trading platform, accounting or ERP client that ships as an .exe	Windows	You need a Windows desktop session over RDP. This is a workstation-in-the-cloud use case, not web hosting.
Docker or Kubernetes host	Linux	Linux containers are the ecosystem. Windows containers exist but the image catalogue and community are much smaller.
Mail server, DNS, VPN, reverse proxy, monitoring	Linux	Lower RAM overhead, better packages, and the reference documentation for these services is written for Linux.
Game servers (Minecraft, CS2, Rust, Valheim)	Usually Linux	Most dedicated server binaries have Linux builds. Check your specific title first, a few are Windows-only.
Windows-only automation, RPA bots, browser farms with Windows dependencies	Windows	If the automation drives Windows applications, it needs Windows.

Linux vs Windows VPS: The Full Comparison

Dimension	Linux VPS	Windows VPS
Licence cost	None. Ubuntu, Debian, Rocky, AlmaLinux and openSUSE are free to run and redistribute.	Windows Server is licensed per core, with Client Access Licences required for users or devices accessing the server. Hosts usually bill it monthly.
Baseline RAM	A minimal Ubuntu or Debian server image typically idles in the low hundreds of megabytes with no desktop installed.	Microsoft states 2 GB minimum for both Server Core and Server with Desktop Experience on Windows Server 2025, with 4 GB recommended for Desktop Experience.
Baseline disk	A base install typically fits comfortably in a few gigabytes, leaving most of a 25 GB volume for your data.	Microsoft states 32 GB as an absolute minimum for the system partition. Server Core is roughly 4 GB smaller than Desktop Experience.
Remote access	SSH on port 22. Text protocol, key-based authentication, negligible bandwidth, scriptable.	RDP on port 3389, a graphical session. Also PowerShell Remoting and Windows Admin Center. Larger attack surface.
Control panels	cPanel and WHM, Plesk, HestiaCP, CyberPanel, CloudPanel, Virtualmin, Webmin, CapRover, Coolify.	Plesk supports Windows. cPanel does not. Otherwise IIS Manager, Windows Admin Center and Remote Server Administration Tools.
Web server	Nginx, Apache, Caddy, LiteSpeed and OpenLiteSpeed.	IIS, which is genuinely good and tightly integrated with the .NET stack. Nginx and Apache also run on Windows but are rarely the right choice there.
Automation and tooling	Bash, cron, systemd, Ansible, Terraform, Docker, apt or dnf. Effectively every CI/CD example on the internet targets this.	PowerShell (excellent), Desired State Configuration, Task Scheduler, Chocolatey or WinGet. Fewer worked examples for web hosting scenarios.
Security update model	Rolling package updates you apply when you choose. Unattended-upgrades can automate security patches. Kernel updates often need a reboot, though live patching exists on some distributions.	Monthly cumulative updates on Patch Tuesday, applied through Windows Update. Predictable, but reboots are more frequent and take longer.
Typical use cases	Websites, APIs, databases, containers, CI runners, mail, VPN, game servers, anything you want to run cheaply and densely.	Legacy .NET applications, Windows desktop software in the cloud, Active Directory integration, MS Access or Exchange dependencies.

Windows VPS Licensing Cost: What You Are Actually Paying For

This is where honest comparisons usually stop short. Windows Server is not free, and the way the cost reaches you depends on how your provider licenses it.

Microsoft licenses Windows Server under a core-based model, and Client Access Licences are required for every user or device accessing the server. At the time of writing, Microsoft's published suggested retail pricing for Windows Server 2025 lists Standard and Datacenter editions priced per 16 core licences, with Standard in the low four figures in US dollars and Datacenter several times that. Standard edition permits two virtual machines plus one Hyper-V host per licence; Datacenter permits unlimited virtual machines. Those are perpetual purchase prices, not what a VPS provider charges you.

Hosting providers generally do not buy retail licences for your VPS. They use the Services Provider License Agreement (SPLA), which lets a service provider license eligible Microsoft products on a monthly basis during a three-year agreement term, paying only for what they made available that month. SPLA supports per subscriber, per processor, per core and per guest or host models.

Three practical consequences for you as a buyer:

• It is a recurring cost, not a purchase. Stop paying, and the licence stops. There is no asset at the end.
• It scales with the plan. Because SPLA supports per-core billing, an 8 vCPU Windows VPS often costs more in licence terms than a 2 vCPU one at the same provider.
• You cannot always bring your own. Microsoft has specific rules about deploying customer-owned licences on shared multi-tenant hardware. Whether a bring-your-own-licence route is available to you depends on the licence type you hold and your provider's setup. Ask before you assume.

So the only reliable question to ask a provider is: does this Windows VPS price include the Windows Server licence, or do I supply one? Get the answer in writing before you buy. A Windows VPS advertised at the same price as a Linux one either bundles the licence into a higher price elsewhere or expects you to bring it.

Our own published VPS plans are KVM instances with full root access and a choice of operating system. Because Windows licensing terms vary and change, ask us directly what is available on your plan rather than assuming. If the answer changes your budget, that is exactly the point of asking early.

"We're a .NET Shop" Is No Longer a Windows Requirement

This is the single most useful correction in this article, and it is the one most comparison posts get wrong because they were written from an outline that predates 2016.

Microsoft's documentation is unambiguous. Modern .NET is described as "a free, cross-platform, open-source developer platform", runs on Linux, macOS and Windows, and supports Arm64, x64 and x86 architectures. It ships annually each November. ASP.NET Core, the web stack that runs on it, has first-party Microsoft documentation for hosting on Ubuntu, RHEL and SUSE with Nginx as a reverse proxy in front of Kestrel, managed as a systemd service.

So the real question is not "are you a .NET shop". It is which .NET.

How to tell which .NET you actually have

• Open the .csproj file. A TargetFramework value like net8.0, net9.0 or net10.0 means modern .NET, which is cross-platform. A value like net48 or v4.7.2 means .NET Framework, which is Windows-only.
• Look for Web.config and Global.asax. Strong signals of .NET Framework and the older ASP.NET pipeline.
• Look for Program.cs with a WebApplication builder and appsettings.json. Strong signals of ASP.NET Core.
• Check for WebForms (.aspx files with code-behind), WCF services, or System.Web references. These generally do not port. Windows it is.
• Check for Windows-specific APIs such as the registry, WMI, Windows Services hosting, or System.Drawing.Common on older versions. Each one is a small migration task rather than a blocker, but they add up.

Microsoft describes .NET Framework as "actively supported, in maintenance" and modern .NET as the one that is evolving. If you are starting anything new, there is no technical reason to be on Windows for it.

And the database

The other half of the assumption is SQL Server. Microsoft's documentation states plainly that SQL Server runs on Linux starting with SQL Server 2017, uses the same database engine as on Windows, and is supported on Red Hat Enterprise Linux and Ubuntu for versions 2017 through 2025, plus containers. Availability groups, TDE, Always Encrypted, SQL Server Agent and Query Store all work there. Note that SQL Server itself is separately licensed regardless of the operating system underneath it, so putting it on Linux saves you the Windows licence, not the SQL Server one.

Net effect: a modern ASP.NET Core app talking to SQL Server can run entirely on a Linux VPS. Plenty of teams do exactly that to avoid the Windows licence line item.

RDP Is Not SSH: The Security Difference Nobody Budgets For

If you choose Windows, this section is the price of admission. Read it.

SSH is a text protocol with a small attack surface and a mature key-based authentication model. Turn off password authentication, allow only public keys, and the brute-force problem largely disappears. Fail2ban or a firewall rule mops up the rest.

RDP is a graphical session protocol with a much larger surface, and it is scanned and brute-forced relentlessly on port 3389. Microsoft's own Azure network security best practices are blunt about it: disable direct RDP and SSH access to virtual machines from the internet, because attackers use brute-force techniques to gain access and then use the machine as a launch point. Microsoft's recommended alternatives are a VPN connection, a bastion host, or just-in-time port access that only opens after approval.

Translating that to a VPS without an Azure control plane, here is what you should actually do on day one:

• Do not leave 3389 open to the world. Restrict the firewall rule to your own IP addresses, or better, install WireGuard or OpenVPN on the VPS and reach RDP only over the tunnel.
• Keep Network Level Authentication enabled. It forces authentication before a session is established, which blocks a whole class of pre-auth attacks. It is on by default; do not turn it off for a convenience reason.
• Rename the built-in Administrator account and never use it day to day. If you leave the default name in place, an attacker only has to guess the password, not the username.
• Set an account lockout policy. Windows will not slow attackers down on its own.
• Add multi-factor authentication through RD Gateway or a third-party MFA agent if the machine holds anything that matters.
• Changing the port from 3389 is not security. It reduces log noise from indiscriminate scanners. It does not stop a targeted scan. Do it if you like, but do the items above first.
• Patch on schedule. Windows Update on a monthly cadence, with reboots planned rather than deferred forever.

The same principles apply to a Linux box, and our VPS security hardening checklist walks through the Linux side step by step. The difference is that a badly configured Linux VPS with key-only SSH is still reasonably hard to break into. A badly configured Windows VPS with RDP open to the world and a password of moderate quality is a matter of time.

Plan Sizing: Why a Windows VPS Needs a Bigger Plan

This is the part that catches people out at checkout. You compare two providers, see similar prices, buy the Windows plan at the same tier you would have picked for Linux, and then spend a month wondering why everything feels sluggish.

Microsoft's published hardware requirements for Windows Server give you hard numbers to plan against. For Windows Server 2025 the stated minimum is 2 GB of RAM for Server Core and 2 GB for Server with Desktop Experience with 4 GB recommended, and 32 GB of disk as an absolute minimum for the system partition. There is also a specific warning that installing on a virtual machine configured with one processor core and 1,024 MB of RAM fails, and that you should allocate at least 1,280 MB during setup.

Those are minimums for the operating system to exist. They are not what your application gets. Map that onto our VPS ladder and the picture is clear:

Plan	Specs	Linux suitability	Windows suitability
Nano	1 vCPU / 1 GB / 25 GB NVMe	Fine for a small site, a bot, a proxy or a staging box.	Below Microsoft's stated minimums on both RAM and disk. Not a Windows plan.
Micro	1 vCPU / 2 GB / 50 GB NVMe	Comfortable for a cached WordPress site or a small API.	Meets the bare minimum only. Expect the OS to consume most of it.
Starter	2 vCPU / 4 GB / 75 GB NVMe	Room for a full LEMP stack plus caching.	The realistic floor for a usable Windows VPS running one light application.
Basic	3 vCPU / 6 GB / 100 GB NVMe	Multiple sites, or one busy one.	A sensible starting point for IIS plus a small SQL Server Express instance.
Advanced and above	4 vCPU / 8 GB / 125 GB NVMe and up	Serious application workloads, containers, CI.	Where a Windows application with a real database belongs.

The rule of thumb worth remembering: for the same application, budget one to two tiers higher on Windows than on Linux, then add the licence cost on top. That combination, not the raw plan price, is the honest total.

One meaningful lever exists on the Windows side. Choosing the Server Core installation option instead of Server with Desktop Experience removes the graphical shell, and Microsoft notes a Server Core install is roughly 4 GB smaller on disk. You manage it with PowerShell Remoting and Windows Admin Center from another machine. If your workload is IIS serving an ASP.NET application and nobody needs to click around a desktop, Server Core is the better engineering choice. If you bought Windows specifically to run a desktop application over RDP, it is not an option.

Control Panels, Management and the Day-to-Day

Control panel availability is a real practical difference and it usually favours Linux.

cPanel and WHM, the panel most shared-hosting refugees already know, is Linux-only. If you want that specific interface on a virtual server, you need a Linux VPS, and our guide to cPanel VPS hosting covers the licensing and setup. Plesk is the main cross-platform option and runs on both Linux and Windows, which is why it dominates the Windows shared-hosting market. The free panels worth knowing, HestiaCP, CyberPanel and CloudPanel, are Linux-only.

On the Windows side, the tooling you actually live in is IIS Manager for sites and application pools, Windows Admin Center for browser-based server management, and PowerShell for everything repeatable. PowerShell is genuinely excellent and better designed than Bash in several ways. The gap is not quality, it is ecosystem: the number of web hosting tutorials, Ansible roles, Docker images and Stack Overflow answers that assume Linux is not close.

There is also a difference in how you recover from mistakes. On Linux, most configuration is a text file you can diff, version and restore. On Windows, meaningful state lives in the registry, in IIS configuration and in service definitions, which is manageable but less transparent when you are trying to work out what changed at 2am.

Windows Server vs Ubuntu for Hosting: Picking the Distribution

If you have landed on Linux, the follow-up question is which distribution, and it matters less than people think.

• Ubuntu LTS is the safe default. The largest volume of tutorials and vendor documentation targets it, including Microsoft's own ASP.NET Core on Linux guidance. Long-term support releases get five years of standard support.
• Debian is Ubuntu's upstream, more conservative, slightly lighter, and excellent if you value stability over recent package versions.
• AlmaLinux or Rocky Linux are the RHEL-compatible choices. Pick one of these if you need cPanel, if your team has RHEL habits, or if a vendor certifies against RHEL.

Any of the three will run your workload. Choose the one whose documentation you will be reading at 2am, and stick to a version that still has years of support left rather than the newest release.

When Windows Is Genuinely the Right Call

Being even-handed means naming the cases where Windows wins outright:

• Your application targets .NET Framework and a rewrite is not funded. Migration is a project; a licence is a line item. Sometimes the line item is correct.
• You need to run a Windows desktop application in the cloud, over RDP, on a machine that is always on. There is no honest Linux substitute for this.
• You need Active Directory integration, Windows Authentication, Group Policy or an Exchange dependency.
• Your team has deep Windows operations skill and no Linux skill, and the workload is small enough that the licence cost is less than the cost of learning under pressure.
• A vendor supports their software only on Windows and you need that support contract to be valid.

Notice that four of those five are about constraints, not preferences. That is the correct shape for this decision.

When a VPS Is the Wrong Product Entirely

Worth saying plainly, because it saves people money. If you are running one brochure site or a small WordPress install and you do not want to be responsible for operating system updates, neither a Linux VPS nor a Windows VPS is your answer. Managed shared hosting costs less and takes the patching off your plate. A VPS is an arrangement where you trade maintenance work for control and dedicated resources, and if you do not want the maintenance work, you will end up with an unpatched server. Our breakdown of what cheap VPS hosting really buys you goes through that trade in detail.

Linux vs Windows VPS: The Verdict

Choose Linux unless something in your application forces your hand. The saving is not just the absent licence, it is the smaller baseline, the smaller plan, the smaller attack surface, and an ecosystem where the answer to your problem was written down by someone else three years ago.

Choose Windows when a real dependency demands it, and when you do, budget properly: one to two plan tiers higher, plus the licence, plus the time to lock down RDP before the machine ever faces the internet. A Windows VPS run well is a perfectly good product. A Windows VPS bought at Linux specs with RDP wide open is the most commonly compromised thing in small-scale hosting.

If you know which side of the line you are on, our KVM VPS plans give you full root and a choice of operating system, with free migration if you are moving an existing workload. If you are still unsure which stack your application actually needs, tell us what it is built with and we will tell you honestly, including when the answer is that you do not need us.

Frequently Asked Questions

Is a Windows VPS slower than a Linux VPS?

Not inherently, on identical hardware. What differs is overhead: Windows Server reserves more RAM and disk for the operating system itself, so at the same plan size your application has less left. Compare like for like by adding one or two tiers to the Windows plan, and the performance gap mostly disappears along with the price advantage.

Do I need a Windows VPS to run a .NET application?

Only if it targets .NET Framework. Modern .NET, formerly .NET Core, is cross-platform and Microsoft documents hosting ASP.NET Core on Ubuntu, RHEL and SUSE behind Nginx. Check the TargetFramework line in your project file: net8.0 or later runs on Linux; net48 or similar does not.

How much does a Windows Server licence add to a VPS?

It depends entirely on how your provider licenses it. Windows Server is sold per core with Client Access Licences on top, and most hosts resell it monthly through Microsoft's SPLA program, often scaling with vCPU count. There is no universal figure, so ask your provider whether the advertised price includes the licence before you buy.

Can I run SQL Server without a Windows VPS?

Yes. SQL Server has run on Linux since SQL Server 2017, on Red Hat Enterprise Linux and Ubuntu, using the same database engine as the Windows version. Bear in mind SQL Server is licensed separately in either case, so this saves the Windows Server licence, not the SQL Server one.

Can I switch a VPS from Windows to Linux later?

You can reinstall the operating system on a KVM VPS, but it wipes the disk. Treat it as a migration, not a toggle: back up your data, stand up the new environment, test it, then cut over DNS. Because switching is disruptive, spend the extra hour on the decision now rather than discovering the mismatch in month three.

Is RDP safe to leave open on a VPS?

No. Microsoft's own Azure guidance recommends disabling direct RDP access from the internet because attackers brute-force it continuously. Restrict port 3389 to your own IP addresses or reach it through a VPN tunnel, keep Network Level Authentication on, rename the Administrator account, and set an account lockout policy.
