6 Open Source Alternatives for Windows Server

As you all know, Microsoft, the well known software developer and world leader in Operating Systems, offers users solutions for servers in the form of the dedicated OS called Windows Server. A few months back, when Microsoft unveiled Windows 8, we also saw the server version of this OS, Windows 8 Server.

Although Microsoft offers very useful tools for server management, their products sometimes cost quite a lot, and therefore, administrators are looking for cheaper solutions to run their servers. These alternatives are open source operating systems designed for servers and they are free or cost less than a Windows based server OS, thus, making them a very profitable solution.
The world’s best known open source software (although not a server OS) is the already well known Android OS. The Android OS has its roots the Linux OS and it’s free for anyone to download and install or develop other versions (we know these as custom ROMs).

What is a open source server OS?

A open source alternative for Windows Server is a operating system that is free for use and can accomplish the same tasks as the Windows Server OS. You might be surprised to see that there are lots of such open source operating systems intended for different kinds of servers on the web and they do a great job as well. I’ll show you a few such open source alternatives for Windows Server.
These open source operating systems are used by network administrators for small businesses with a low number of connected computers or for home networks. They can act as network gateways, printing servers or network monitoring or for file sharing and streaming and many more.

The Linux Server OS

Linux is a well known name when it comes to servers. There are thousands of servers worldwide running Linux/Apache OS and it’s probably the biggest developer of open source alternatives for Windows OS. However, the Linux server OS is not free, but its cost is much more acceptable and it comes with many advantages, like less downtime, higher security and much higher level of stability.
Linux has given us over the years plenty open source operating systems, and we have all saw how good they are, and the server software is based on those Unix operating systems, therefore bringing with them the same advantages. I mentioned this because almost all the other open source alternatives for Windows Server are based on the Linux OS or some Linux distribution.
