Web Hosting companies offers web servers mainly based on two type on Operation System. Linux OS and Windows Server OS. Among these we have here to explain which is best in terms of different selection criteria.
Performance: Linux Server
Linux server performance is better than Windows server. Linux uses less amount of RAM, less disk space for installation. Even booting time for Linux is very fast than Windows. Usage of Hardware resources is pretty much less in Linux.
Usability: Linux Server
Usage of Linux is very simple without GUI. Just need to know few Linux Administration commands. Whereas Windows need a GUI interface to handle. It can also be used by Terminal similar to Linux but I found Linux as simpler. Linux provide root access to user but Windows restrict root access.
Resource: Linux Server
Online resources to learn Linux Server are available more than Windows Administration. Being simpler and open sources, made the Linux favorite for developers. Also due to root permissions in Linux, its easier for them to use, develop and customize according to the need.
Robustness: Linux Server
Linux is free and open source, while Windows is paid software with limited licensing control. Hence moving the installation from one system to other or on multiple system is merely possible for Windows.
Customization: Linux Server
Linux OS can be customized easily according to our need. We can improve performance, add or install apps, software, etc. by using terminal. It is hardly possible for Windows server to customizes, we need to pre-order the customized version, if need and that may charge some extra bucks.
Pricing: Linux Server
As Windows is property of Microsoft Corp. it is being charged based on licence copy. Whilst Linux is open source software and freely available to download, install, develop and sell.
Support: Windows Server
Linux OS is support by open community developers which help to make it better, while Microsoft Windows servers is backed by experience and well trained developers.
Note and Conclusion:
Keeping all above mentioned points we recommend to use Linux server based OS of any web hosting. And most of webmaster prefer to go with Linux OS.
