What is the difference between Linux and Windows hosting?

Today, there are over a billion websites globally, and nearly all of them are hosted. According to W3Techs data, more than 57% of all web servers run on Linux, while Windows hosting occupies a smaller yet stable niche, thanks to the support of Microsoft products. 

The difference between these two systems may seem unclear to beginners. Both refer to where a website, its files and data are stored. However, the choice of platform significantly impacts page loading speed, security, stability, and even the overall cost of the project. These two hosting options do differ, one of them is definitely better suited for your project. Let’s find out which one of the two it is.

What is Linux hosting

Linux hosting involves placing a website or web application on a server running the Linux operating system. This system is known for its stability, flexibility, and open-source code.

Why do companies use Linux hosting?

• No licensing fees. Linux is an open operating system, meaning it doesn’t require licensing fees.
• Security and stability. Linux has a strong reputation for security and stability. It’s less susceptible to attacks due to strict privilege segmentation, where the administrator must explicitly allow software installations.
• Active community. A large and active community provides numerous materials, forums, and educational resources (like Stack Overflow, YouTube, and various courses) for working with Linux hosting.
• Support for LAMP Technologies. Linux offers broad support for LAMP technologies, which include Linux, Apache, MySQL/MariaDB, and PHP/Perl/Python. This stack is standard for many web developers and CMS platforms like WordPress and Joomla.
• Large-scale Infrastructure. Fun fact: every. Single. One. Of 500 of the most powerful supercomputers in the world runs on Linux distributions. Pretty impressive, if you ask us.

What is Windows hosting

Windows hosting involves placing a website or application on a server running the Windows Server operating system from Microsoft. It provides native support for technologies such as ASP.NET, .NET Framework, MSSQL, and Microsoft Access, along with integration with Active Server Pages, Internet Information Services (IIS), and other Microsoft ecosystem components. Windows accounts for 10.5% of sites with known operating systems, compared to 57.5% for Linux.

Why do companies opt for Windows hosting?

• Compatibility with Microsoft products. This is pretty much a dealbreaker for some. Windows Server offers high integration with ASP.NET, Microsoft SQL Server, and Exchange.
• Ease of administration. Switching to Windows hosting is often easier due to a familiar interface and administrative tools, eliminating the need to learn Linux commands.
• VPS preferences. According to a Liquid Web study (2025), 36% of VPS users choose Windows as their operating system, while 28% prefer Ubuntu and 9% choose CentOS.

Main differences between Linux and Windows hosting

Supported technologies

Linux is a perfect match for the classic LAMP stack, which combines Linux, Apache (or Nginx), MySQL/MariaDB, and PHP/Perl/Python. Most Linux distributions come with the entire stack available from repositories, allowing you to quickly set up a typical web platform right out of the box. Consequently, the vast majority of PHP sites historically run on LAMP/LEMP. Most popular CMS platforms, like WordPress, Joomla, and Drupal, are built on this stack.

If your project is based on PHP and a popular CMS, the “path of least resistance” is almost always Linux + LAMP/LEMP. This combination offers compatibility with requirements, fast deployment, extensive documentation, and automation tools.

On the other hand, if your website or application is built on ASP.NET/.NET and uses an MS SQL database, choosing Windows hosting is more straightforward and logical. This is a “native” Microsoft environment where everything works seamlessly together—think IIS web server, .NET Framework, SQL Server drivers, web.config with URL Rewrite rules, deployment via Web Deploy, and domain authorization (Active Directory/Windows Authentication). This stack is particularly convenient for corporate portals, CRM systems, internal applications, and reporting. While .NET Core can run on Linux, Windows typically requires less manual configuration and offers more official tools and integrations right out of the box.

Security and stability

Linux generally maintains high uptime. Updates are installed incrementally, and in some distributions, the kernel can be patched “on the fly” without needing a reboot. The permissions model is strict, allowing the admin to distribute only the necessary privileges, while additional isolation mechanisms (like SELinux/AppArmor) limit the impact of potential hacks. Thanks to its open-source nature, patches are released quickly, and with automatic updates enabled, the “vulnerability window” is significantly shorter.

Windows, on the other hand, is robust “out of the box.” It comes with Microsoft Defender, SmartScreen, and BitLocker disk encryption, along with centralized updates and policies via the domain, ideal for unified corporate rules. Within the Microsoft ecosystem (IIS, AD, .NET, MSSQL), this setup allows for simple integration with minimal manual configuration.

In summary, if minimal downtime and fine-grained security customization are priorities, Linux is often the preferred choice. If unified management and deep integration with Microsoft infrastructure are essential, Windows is the more rational option. However, in both cases, discipline is key. Competent configurations, timely patches, backups, and monitoring are critical.

Performance and scalability

On the same hardware, Linux often delivers slightly better performance because the OS is lighter and more resource-efficient. Additionally, these servers are easier to “overclock” to handle traffic growth. Scaling and fine-tuning a typical LAMP/LEMP stack can be done quickly, as highlighted by practical hosting reviews.

Windows servers are stable but tend to be more resource-intensive due to the graphical interface and services within the Microsoft ecosystem. If you need a “lighter” installation, consider using Server Core, it has a smaller disk size, fewer components, and, as a result, less overhead.

Ultimately, the performance difference depends on the scenario and setup. For PHP/Nginx, Linux often comes out on top, while for .NET applications under IIS, the native Windows environment is more convenient and predictable. Regardless, web server configuration and tuning (worker model, caching, compression, HTTP/2/3) are just as crucial as the OS itself.

Many of the largest internet giants, including Google, Facebook, and Twitter, rely on Linux servers for their flexibility and reliability. Meanwhile, large corporations that actively use Microsoft products tend to prefer Windows hosting for its compatibility with their existing infrastructure.

Flexibility and customization

On Linux, you can easily assemble a stack tailored to your needs. You can choose your web server (like Apache, Nginx, or LiteSpeed), select PHP versions, and decide between MySQL/MariaDB or PostgreSQL. You can also configure modules and extensions, automating everything through package managers and SSH/scripts. This flexibility makes LAMP/LEMP highly configurable in terms of performance and security.

In contrast, Windows serves as the “home” for Microsoft technologies, featuring IIS, ASP.NET/.NET, MS SQL, and integration with Active Directory and corporate authentication. This setup accelerates deployment and minimizes the need for manual workarounds. While running PHP/MySQL on Windows is possible, the .NET ecosystem offers a more predictable environment.

Cost

Linux hosting is typically more affordable because IT’S FREE and doesn’t require licensing fees. Providers don’t incur costs for using Linux, allowing them to offer more budget-friendly plans. The only additional expense you might face is for the control panel, such as cPanel or Plesk.

On the other hand, Windows hosting tends to be pricier due to licensing requirements. Windows Server operates on a “pay-per-core” model, with basic licenses starting around $139 and going up for enterprise editions. Providers pass these costs onto customers, resulting in higher final plan prices.

Criteria	Linux hosting	Windows hosting
Technological compatibility	PHP, MySQL, CMS, open-source stacks	.NET, ASP.NET, MSSQL, Exchange
Cost	No licenses, cheaper	Requires a license, more expensive
Technical skills	Requires experience, command line	Simple GUI, friendly

Support	Community, rare costs	Official services, but more expensive
Usage in VPS	Widely used, especially for open-source projects	A common choice for .NET and enterprise software

When to choose Linux over Windows

Choosing the right hosting environment is crucial for the success of your project. While both Linux and Windows hosting have their advantages, certain scenarios make Linux the clear winner. Here are some key situations where opting for Linux is the best choice:

• Your stack is PHP/CMS. If you’re using platforms like WordPress, WooCommerce, Joomla, or Drupal, Linux is the way to go. For instance, WordPress officially requires PHP 8.x and MySQL/MariaDB; a typical configuration is LAMP/LEMP on Linux. This setup serves as the “native environment” for the most popular CMS.
• You need your cPanel. If you’re looking for classic shared or VPS hosting, cPanel officially supports only Linux distributions (like AlmaLinux, CloudLinux, Rocky, and Ubuntu). There are no cPanel releases for Windows.
• You actively use Apache/Nginx features. Utilizing features at the site level is typical for Linux hosting, making it a better fit for those who rely on these technologies.
• Cost of ownership is a concern. Linux is a free and open OS (GPL), meaning providers don’t incur additional costs for the OS. In contrast, Windows Server operates on a per-core licensing model, which can add to your expenses.
• You need maximum compatibility with the “mass web stack”. As we’ve already mentioned (extensively), Linux powers about 57.5% of sites where the server OS is known, compared to 10.5% for Windows. This indicates that the CMS and web server ecosystem is primarily Linux-based.
• You prefer familiar SSH tools and DevOps practices. Most web hosting guides and scripts are designed for a Linux environment (like Nginx/Apache, systemd, crontab, etc.), simplifying setup and automation—especially when scaling LAMP/LEMP.

When to choose Windows over Linux

While Linux hosting is a popular choice, there are specific scenarios where Windows hosting is the better option. Here are some key situations that make Windows the ideal choice for your project:

• Your application is on ASP.NET/.NET. If your application is deployed on IIS, ASP.NET Core is officially supported with the .NET Hosting Bundle. IIS processes requests via HTTP.sys and the ASP.NET Core module, making it a natural fit for .NET applications.
• IIS capabilities are required. If you need features like web.config, URL Rewrite, and Active Directory (AD) integration, Windows hosting is essential. Routing and rewriting rules are set in web.config via the URL Rewrite module, and Windows Authentication (Kerberos/NTLM) is available for corporate single sign-on (SSO).
• Technologies or dependencies require the Windows stack. If your project relies on .NET Framework libraries or technologies not available in the cross-platform .NET, Microsoft recommends sticking with the .NET Framework, which means using Windows. Additionally, classic ASP/COM and integration with Access/IIS also necessitate a Windows environment.
• MSSQL support and Microsoft integration are needed. Windows hosting simplifies the combination of IIS, ASP.NET, and SQL Server, along with scenarios involving domain authentication and corporate infrastructure.
• You want a single panel for a mixed fleet. If you need to manage both Linux and Windows environments, consider using Plesk. Plesk is compatible with both operating systems, and current system requirements confirm support for Windows Server 2016/2019/2022/2025. This is particularly convenient if some projects are on .NET/MSSQL while others are on PHP.
• The official ecosystem and SLA from Microsoft are important. If you’re ready to invest in licensing, keep in mind that Windows Server is licensed per core, requiring a minimum of 8 core licenses per processor and 16 core licenses per server. This licensing structure is a key factor in determining the overall cost of Windows hosting.

Choosing between Linux and Windows hosting isn’t about determining which is better overall. It’s about aligning with your project’s specific needs.

Linux is a versatile and cost-effective option for most websites, including those built on WordPress, Drupal, Joomla, and PHP/Python projects, as well as the classic LAMP/LEMP stack. It delivers solid performance, stability, and flexibility, along with a wide array of control panel options and providers.

On the flip side, Windows is the logical choice for the Microsoft ecosystem, particularly for applications using ASP.NET/.NET, MS SQL, and integration with IIS and corporate infrastructure (like AD/SSO). Here, compatibility and official support are crucial, even if it comes at a higher cost.

In a nutshell

• Technologies. PHP/MySQL and popular CMS → most often Linux; ASP.NET/MSSQL/IIS → Windows.
• Budget. Generally, Linux environments are cheaper due to the absence of OS licensing fees.
• Administration. Prefer a GUI and the Microsoft ecosystem? Go with Windows. Need flexibility and fine-tuning? Linux is your best bet.
• Scalability and performance. For typical web loads, Linux is easier and more cost-effective to scale. For the Microsoft stack, sticking with the “native” Windows environment is more reliable.
• Mixed fleets. If you require both OSes and a single management panel, consider the Plesk options offered by your provider.

So, here’s the thing. Use Windows when your project is tied to .NET/MSSQL and Microsoft corporate services. Use Linux for everything else. This strategy minimizes risks, simplifies support, and keeps costs predictable (and makes your admin happy). What else does one need?
