Linux is a very popular platform. Not just because it is free but also because it is reliable and supports anything you can imagine. A popular setup is a Linux server without any graphical user interface. It can be used for web hosting, as a file server, as a database server, or for anything you need. Most people comfortable with Windows operating system are afraid to start thinking in a different way. In fact, installing and using Linux is pretty simple.
Quite a few people have a tendency to dabble in Linux. This means that from time to time, they might download a distribution, burn it to a Live CD, and try it out on their computer without actually installing it to their machine. If you are a Windows user who is doing this, you need to try Linux on a dedicated computer.
Once you decide to go for it you have already made the first step. The next step is to get some basic information about installing Linux. There are many Linux distributions. One that is very popular is Ubuntu. Simply Google for “ubuntu server” and learn about what do you need to install Linux. In general, things are pretty simple. You can install Linux on almost any machine. Your old computer that was replaced some time ago is a perfect choice for Linux. You only need some space on the hard drive, a CD or DVD drive, a network card and a lot of patience.
The first step is to make a bootable CD with the latest Ubuntu server image. Download the image file and burn it on a CD. Then you boot your computer with this CD and start installing Linux. It is a good idea to do this installation next to your main computer with internet accesses. This way you will be able to browse for any problem you may encounter. The most important thing you should know is that for every question you may have, there is an answer on some web page waiting for you. You only have to find it.
The installation process is pretty straight-forward. If you don’t understand what the installer is asking you then simply select the default option. Of course, you can also ask Google for it and then choose appropriate option. You should understand that the Linux principle is very different from the Windows one. But once you become familiar with Linux shell and basic commands it will be very easy to work with Linux and to install and configure new software.
Having a server is a great upgrade to your home network. This server will be your reliable storage for large peer-to-peer files, web server for website development or a computer to play with. And remember, sooner or later you will encounter a problem. Something will not work or you will not know how to change some setting. All you have to do is to search for the answer on the web. Web pages offer a giant encyclopedia on Linux.

So what is Server Virtualization anyway? That’s a good question. Virtualization is the act of using virtual servers or software, to reduce the amount of physical servers needed to power an organization’s IT infrastructure. With that said, virtualization cuts costs by reducing energy consumption and server room cooling expenses. This article, originally written by Matt Peterson, will explain Application Virtualization and Server Virtualization in full detail. More:
There is a lot of buzz going around about Virtualization. What is Virtualization, and what benefits does it provide? In this article we will take a look at the technology to see how it can provide a great deal of flexibility and cost effectiveness for IT professionals and software developers.
Virtualization technology allows multiple virtual machines to run on a single host computer. These virtual machines can run different operating systems, such as Windows, Linux and UNIX. Each virtual machine has its own set of virtual hardware resources (e.g., CPU, RAM, Hard Drive, etc) allowing the operating system to run as if it were installed on a physical machine.
The benefits of Virtualization technology are far reaching. Many organizations have moved to the virtual machine solution to consolidate multiple servers, running side by side on a single physical machine. Server consolidation allows IT professionals to fully utilize server resources, while isolating virtual machines and allowing them to run different operating systems and applications. Software developers utilize virtual machine technology to quickly test applications on different operating systems, without the hassle of setting up multiple physical machines for testing or taking the risk of causing problems by testing in a production environment.
You can run Virtualization software on pretty much any platform. Once the software is installed it is simple to create virtual machine instances. Virtual machines are just a set of files located on the host machine. You configure your virtual machine settings on the host computer, install the operating system and you are ready to go. It is a very common practice to use a master image of a virtual machine. This master image can be a fully configured machine, with the operating system and all required applications installed. You can then rapidly deploy virtual machines by copying the master image to multiple Virtualization hosts to provide zero downtime and 100% server availability.
There are a number of Virtualization products available. VMWare, which is probably the most popular, recently announced that it will be releasing a free version of its GSX Server product. This will allow any organization to host virtual machines on either Windows or Linux hosts. Other Virtualization products include Microsoft’s Virtual Server and SWsoft’s Virtuozzo, just to name a few.
