Dedicated Server Hosting

Linux and Windows Dedicated Server Hosting platform both have their merits and demerits. Following are few important points which are to be kept in mind before choosing your hosting platform.

Security :

Most webmaster have misunderstanding that windows servers are more vulnerable than Linux servers but this is not true. Security issues are responsibility of administrator rather than OS. Even Linux server can be hacked if not handled properly.

If you have latest updated security patches and software for your server and is monitored round the clock by your administrator then there should not be any issue for your server so for security issues look for your server management staff rather them OS.

Access :

Both Linux and Windows Dedicated Servers Hosting plans offer you server access via FTP. Linux offers you SSH and telnet access whereas Windows hosting supports telnet and RPD for accessing server.

Databases :

Microsoft owned databases such as MS Access, MSSQL 2000, MSSQL 2005 etc are supported on Windows Hosting Plans where as MySQL is suited for Linux Hosting, although MySQL can be used with Windows Hosting too.

Cost :

Comparatively cost of Linux Dedicated Server hosting is cheaper then Windows Dedicated Server hosting. As Linux is open source and is free thus overall cost for Linux hosting gets reduced so it’s most preferred hosting platform. There was a time where operating systems made a big difference. Currently, most platforms are supported on both Linux and Windows.

Before we proceed towards the tutorial for Reinstallation of GRUB boot loader on Linux Dedicated Servers, I would suggest you to have a look at the short description about GRUB boot loader which is given below.

Most of us who belong to the web hosting industry are well aware of the fact that the products and applications released under the GNU project are free. GRUB is also a boot loader package which is available for free i.e. it is released under the GNU project. Now, I would like to explain what does GRUB do.

GRUB is actually one of the multiboot specification which will allow you to install and run 2 different operating systems of the same machine. As you will have 2 different operating systems installed on the machine, you will need an option to select the operating system you wish to run when the machine starts, otherwise this feature won’t be useful. This option is available if you have GRUB installed on the Linux Dedicated Server Hosting. Alongwith this feature, you can also select different images of the kernel and pass boot time parameters on a single operating system’s partitions to such kernels.

Most of the hosting providers who offer Linux Dedicated Servers will assist you to install GRUB boot loader on the Linux Dedicated Servers, however, it might be possible that you will have to reinstall it on your Linux Dedicated Server Hosting.
