We prefer Linux and we offer only Linux web hosting, many of Linux variants and programs are free (open source) or mush lower in prices unlike Windows. Also, security and reliability are better compared to Windows.
Linux and Windows are two popular operating system. On comparing those two Linux is best than Windows. Linux is virus free platform. It is a open source. We can get softwares at free of cost. Linux is more secure than Windows. We can manage more number of files and folders in Linux but theses are not possible in Windows. So Linux is best for web hosting.
I am here to help you. Before choosing a hosting provider you should be clear about the server either with Windows or Linux. I would recommend you to host your website in Linux server. Because Linux has more advantages over Windows. Linux is open source, virus free platform, free softwares, manage more files etc... But these are some what not possible with Windows.
Linux and windows are from two different worlds while Linux runs most of the internet, windows market share is based more on the high level corporate world. The large companies and military mainly use windows to run their .asp .aspx applications. The main problem with windows is when it tries to live in the Linux world and think it can survive which it cannot.
From a hosts perspective windows is a pain in the ass since the market at our level is very small and windows nickel and dimes you to death with licensing everything including how may procs our nodes have. And windows freezes and eats up RAM like its free, its much harder to keep a windows machine online than a Linux.
Although many people consider Linux to be more secure than Windows, both operating systems are equally secure. Security really depends more upon the server setup and the administrators running the server. All of HostGator's managed servers are maintained with the latest security and performance patches and configured for optimal security.
Both operating systems have their ups and downs, one of the main reasons that Linux is so raved about in the web hosting industry is the fact that the software is open source. This gives you a lot more control over the way the operating system and the software you are using functions. IIS may be a great web serving software, in the end however Windows in its entirety is more resource intensive than a core linux distribution. Linux allows you to cut out all the bloatware (including the desktop environment) for more operating capacity.
Another huge thing is cost, as a Microsoft Partner & SPLA member I understand that Windows is priced specifically for Enterprisee use, and thus this can be an inconvenience for a lot of people (operating cost to revenue ratio), whereas Linux is free in most cases.
Another is Control Panels, when it comes to hosting websites the most widely adapted control panel happens to be cPanel/WHM. I know some years back cPanel attempted to enter the Windows market by developing Enkompass, and though the software was great, the heavy restrictions set forth in Windows prevented them from providing customers with the functionality that cPanel customers have all grown to love. Plesk, though also popular, still lacks a huge amount of features that are looked at by customers as well.
Next off is web-software compatibility. A lot of open source software is developed to utilize technologies that are mainly powered by Linux based servers. This can cause conflict from time to time.
It is true that there is a cost difference using Windows. Microsoft is very proud of their products!
Windows 2012 Server DataCenter Edition and SQL Server Enterprise will cost you some $$$$$$, but if your needing a single server, 2012 Standard/SQL Express is not bad at all.
Plesk got a bad rap with their older versions (pre v11). There were a lot of missing features and bugs. Update fixed some problems, but created new ones. I believe V12 is much improved. A lot of the cPanel/Plesk decision boils down to personal preference and what your more familiar with.
I really don't care which OS people prefer (although I do enjoy a good debate and playing "devils advocate"). I'm not trying to persuade everyone that Windows is better. I'm simply trying to understand the hatred for Windows. All the time I hear that people can't run php sites on Windows, but I have yet to see one that wouldn't work!
