The operating system is the first real decision when you order a server. The right choice is usually decided by one question: what software do you need to run? This guide compares a Linux VPS and a Windows VPS on software, access, skills and resource use, so you can choose once and not have to rebuild later.
Before you start
Write down the main programs you will run on the server. Check each one's system requirements: does it run on Linux, Windows or both? That list will answer most of this guide for you.
Start with your software
Software that points to Linux
- Websites with WordPress, Joomla or other PHP apps on Nginx or Apache.
- Apps written in Node.js, Python, Go, Ruby or PHP.
- Docker and Docker Compose stacks.
- Databases such as MySQL, MariaDB, PostgreSQL and Redis.
- Most Discord and Telegram bots, scrapers and automation scripts.
- Many game servers, VPNs and self-hosted tools.
- Control panels such as cPanel, Plesk or DirectAdmin on Linux. You buy one from the vendor or use a free edition.
Software that needs Windows
- MetaTrader 4/5 and other Windows trading platforms.
- ASP.NET Framework apps, IIS and Microsoft SQL Server setups that depend on Windows.
- Desktop programs that only exist for Windows.
- Anything you want to use through a full graphical desktop.
If your software runs on both, Linux is often the lighter and simpler choice for a server.
How you connect
- Linux VPS: you manage it over SSH, a secure text terminal. You type commands rather than click. See what is SSH.
- Windows VPS: you connect with Remote Desktop (RDP) and see a full Windows desktop. RDP uses port 3389, so you connect to an address such as
203.0.113.10:3389.
Both are secure when set up well. RDP feels familiar if you use Windows every day. SSH feels faster once you learn a handful of commands.
Skills you need
Linux
You will use the command line to install packages, edit config files and restart services. That sounds harder than it is. A small set of commands covers most daily work, and most guides give you copy-paste commands.
Windows
You use the familiar Windows interface: Server Manager, Settings, Control Panel and PowerShell for some tasks. If you already know Windows, the learning curve is gentle.
Either way, you are responsible for updates, the firewall and backups.
Resource use
A Linux server with no desktop uses very little memory for the operating system itself, which leaves more RAM for your apps. Windows Server runs a graphical desktop and more background services, so it needs more RAM and disk before your software even starts.
In practice:
- A small Linux VPS can comfortably run a website or several bots.
- A Windows VPS needs more headroom, especially if you run several programs at once.
See how much RAM a VPS needs for rough figures.
Licensing
Linux distributions such as Ubuntu, Debian, AlmaLinux and Rocky Linux are free to use. Windows Server is licensed software.
Check your choice
Choose Linux when:
- Your software runs on Linux, and
- You are happy to learn some command-line basics.
Choose Windows when:
- You need Windows-only software such as MetaTrader or certain.NET apps, or
- You want a graphical desktop to work in.
Troubleshooting common doubts
- "Can I switch later?": yes, by reinstalling the server with a different OS from your VPS provider's control panel, but a reinstall wipes the disk. Back up first.
- "Can Linux run Windows programs?": tools like Wine exist but are unreliable for servers and trading. Use Windows for Windows software.
- "Can I get a desktop on Linux?": you can install a lightweight desktop and xrdp, but it uses more resources. Most Linux servers run without one.
- "I am not sure which Linux to pick": Ubuntu LTS is a safe starting point for beginners.
