Linux hosting runs PHP, Node.js and Python sites on a cPanel account or a VPS. Windows hosting runs ASP.NET and classic ASP sites on IIS, with Plesk to manage them. Each handles some workloads well and others badly, and the wrong choice is expensive to undo: moving an application between the two platforms usually means rewriting the deployment, the database connection and the configuration. This guide compares the two on the points that decide the choice, and gives a short test to run before you commit.
SiteHarbour offers Windows hosting with Plesk, IIS 10, Windows Server 2022, and .NET Core runtimes from 6 to 10, along with cPanel hosting and VPS plans for Linux workloads. The comparison below applies whichever provider you use.
What decides the platform
The application decides the platform, not the price. Start from what the code needs:
- ASP.NET Core or ASP.NET Framework runs on Windows and IIS. It runs on Linux too, but Windows is the simpler path for most teams that already use Visual Studio and MS SQL.
- PHP, Laravel or WordPress runs well on Linux with cPanel, and most PHP tooling assumes Linux.
- Node.js and Python run on both. Linux is more common for these, and the tooling is built for it.
- MS SQL Server is Windows-native, although it also runs on Linux. MariaDB and MySQL are the standard choices on Linux.
Step 1: List the stack and the dependencies
Write down the framework, the database, the language version, any native libraries and any Windows-only components, such as COM objects or a specific driver. A Windows-only dependency decides the platform by itself. If the list is all open-source and cross-platform, the choice is a matter of cost and team skills.
Step 2: Check the skills you have
A platform your team knows is cheaper to run than one it does not. A team that works in Visual Studio, uses SQL Server Management Studio and knows IIS will be slower on Linux, and the reverse is also true. Count the people who will maintain the site. The hours spent learning a platform cost more than most hosting differences.
Step 3: Compare the operations
Both platforms need patching, backups and monitoring. The differences show up in the daily tasks:
- Deployment. On Windows with Plesk, a Git deploy or a publish-and-upload is the usual route. On Linux with cPanel, deployment is usually a folder upload or a Git pull over SSH.
- Scheduled work. Plesk’s Scheduled Tasks and cron on Linux do the same job with different syntax. See how to set up scheduled tasks in Plesk for the Windows side.
- Troubleshooting. Windows logs go to the Event Viewer and IIS logs. Linux logs go to files you read with
tail. Both are straightforward once you know where they are. - Security. Both need a firewall, timely patches and least-privilege accounts. The Windows plans include server-level malware scanning and a web application firewall, and the Linux plans include the scanning and firewall described in the cPanel plan pages.
Step 4: Compare the cost of a mistake
A platform mismatch costs more than the monthly fee. A Windows-only library on a Linux server means a rewrite, and a Linux-only tool on Windows means a workaround that breaks on each update. Estimate the cost of changing platform later, and compare it with the difference in hosting price. For a long-lived product, the migration cost often decides the question.
Step 5: Run a short proof before you commit
Deploy the smallest version of the application to the candidate platform. Include the database connection, one background task, one file upload and the email send. Those four parts fail first when a platform is wrong. If all four work in a day, the platform fits. If they take a week, the platform is fighting the application.
A simple guide to the choice
- Choose Windows hosting for ASP.NET Core or Framework applications, MS SQL databases, and teams that work in the Microsoft stack. Use Plesk to manage websites, SSL and databases.
- Choose cPanel hosting for PHP, WordPress and Laravel sites that run in a normal web folder, with cron and a simple control panel.
- Choose a VPS for Node.js, Python or any stack that needs root access, a custom service, or a Linux-only tool.
Common mistakes
- Choosing by price. The cheapest plan that cannot run the stack costs the most in the end.
- Ignoring the team. A platform nobody on the team knows slows every fix.
- Assuming the framework is the platform. ASP.NET Core runs on both, so the choice is about the rest of the stack.
- Skipping the proof. A day of testing shows more than a list of features.
Frequently asked questions
Is ASP.NET Core only for Windows?
No. It runs on Linux too. On a Windows plan it is simpler to host with IIS and Plesk, which is why many teams choose Windows for it.
Can I run WordPress on Windows hosting?
Yes, WordPress runs on IIS with PHP, but Linux with cPanel or LiteSpeed is the more common and better-tested route for it. Choose Windows only when another part of the business needs it.
Is MS SQL more expensive than MariaDB?
The plans include it, so the cost is in the plan. The real question is whether the application needs SQL Server features or can use MariaDB.
Can I switch later?
Yes, but it is a migration, not a copy. Plan for a rewrite of the deployment, the database connection and any Windows-only code.
Choose the platform from the application, not from the price. List the stack, check which parts are Windows-only, count the skills on the team, and run a short proof with the database, a background task, an upload and an email send. Then pick Windows for ASP.NET and MS SQL, Linux for PHP and Node.js, and a VPS when you need full control. For the Windows deployment, read how to deploy ASP.NET Core on Plesk Windows hosting.
