However at the present time, many people know that Linux hosting is far more secure than Windows. Windows also has a sophisticated security actually and always updated, it depends on the company providing the website hosting services whether the company can provide good security for their hosting services or not.
Most all linux OS is open source and free of cost. Perhaps this is one of the advantages why many companies are using Linux as a hosting server because it does not need payment for a license fee. Linux hosting in general is more stable and able to provide qualified performance when compared with windows operating system which is needed to handle many processes at the same time.
If you want to use SSH or Telnet access, just like you want to access files directly from the server without transferring it to local storage, certainly it will gives an advantage over linux. Windows hosting server often waste precious time from its users because the downtime is longer than linux. Beside that window needs more resources (hardware) which are more likely to initiate a process, this means that when doing a window reboot it generally will take a longer time.
