Linux vs Windows Hosting
What the Operating System Changes on a Hosting Plan
Linux vs Windows hosting is a choice about the operating system that runs the server, and that choice shapes which software your site can use. Linux is a family of open-source operating systems and is the most common choice for web servers. Windows Server is Microsoft's commercial server operating system, widely used by businesses that rely on Microsoft products.
For visitors, the difference is invisible, because both platforms can serve the same pages. It appears in the technology behind the site: the programming language, the database and the web server software that answers requests.
Software Compatibility and Licensing
The deciding factor is usually what your application needs.
- PHP and open-source software: PHP runs on both platforms, but Linux is the usual home for PHP sites and many popular open-source tools, including WordPress.
- ASP.NET: Applications built with ASP.NET usually run on Windows hosting. Modern .NET applications can also run on Linux, but applications that depend on Windows-only components may not.
- Databases: MySQL and MariaDB are typical on Linux. Microsoft SQL Server is tied to Windows and is often required by existing enterprise applications.
- Licensing: Linux is free to use. Windows and SQL Server require licences, and hosts generally pass those costs into the plan.
Configuration and Day-to-Day Administration
Each platform has its own conventions. Linux hosts commonly run Apache, Nginx or LiteSpeed and support .htaccess files, small configuration files that control behaviour folder by folder. Windows hosts usually run IIS (Internet Information Services), Microsoft's web server, and use web.config files for similar settings. Moving a site between the two means rewriting configuration, not just copying files. The web server programs are compared in the article on Apache, Nginx and LiteSpeed.
Administration differs too. Linux plans often rely on a control panel and command-line tools, while Windows plans commonly use Microsoft's own management tools. Choose the platform your team can support, because familiarity with the system often matters as much as its features.
Two Projects, Two Different Answers
A small business website built on WordPress needs PHP and MySQL, uses open-source plugins and has no unusual requirements. Linux hosting is the natural fit, and it is usually the lower-cost option.
A company with an internal ASP.NET application that stores data in SQL Server needs the Microsoft stack. Windows hosting keeps the application in its supported environment without a rewrite. The higher licence cost is part of the price of running that software. The different plan types are summarised in the overview of hosting types.
Frequently asked questions
Is Linux Hosting Always Cheaper?
Usually the base price is lower on Linux, because there is no operating system licence fee to pass on. Windows and SQL Server licences are often built into plan prices. The total cost still depends on plan size, support and the software you need, so compare full plan details rather than the platform name alone.
Can I Run ASP.NET on Linux Hosting?
Modern .NET applications can run on Linux, and some hosts offer this. Older ASP.NET applications built on the .NET Framework are generally tied to Windows. Check which framework your application uses and which runtime the host supports before choosing. If you are unsure, ask the host directly.
