Virtual Private Servers (i.e. VPS) are created by dividing a single powerful server into multiple virtual servers with individually dedicated resources. The operating system of the Linux VPS is one of Linux distributions (e.g. Debian, CentOS, Ubuntu, etc.), meanwhile the Windows VPS’s operating system is one of the Windows Server versions (e.g. Windows Server 2008, Windows Server 2012, Windows Server 2016, etc.).
Now let us compare the two kinds of VPS.
The cost of a Linux VPS is significantly lower than that of a Windows VPS. This is due to the fact that Linux is a free, open source software, while Windows requires the purchase of a license.
Linux is ideal for open source software such as PHP/Perl, ROR, Java, Python, SSH, CGI, FrontPage Extensions, etc. Windows is perfect for Windows specific applications like ASP Classic, ASP.net, MySQL, C#, VB Development, MS Access, etc. If you wish to get a VPS for the purposes of hosting a site, then if your site’s language is not ASP, Linux will be a more suitable option.
Linux has made tremendous progress in the web hosting security field when compared to Windows. With more professional and user-friendly control panels available on Linux distributions (e.g. cPanel, DirectAdmin, etc.), it can be said that Linux VPS have the edge over Windows VPS when referring to security.
Ease of use:
A command line interface is used when working with Linux (of course, it's possible to install a graphical environment) but Windows has an intuitive GUI (i.e. Graphical User Interface).
In general, a Linux VPS will consume less RAM than a Windows VPS, as in most usage case scenarios, a command line interface is used, while the Windows VPS uses a complex graphical environment. Linux is also widely considered to be more stable than Windows in the web hosting industry. A Windows VPS can be quite resouce hungry if not optimized properly.
We hope that this comparison helps you to decide which VPS you need for the task at hand.
