The basal notion of Virtualization

Since virtualization is at the forefront of technological advances and because every mover and shaker in the commerce (Ibm, Microsoft, Dell, etc. Plus commerce analysts) have solidly endorsed it, you should have some basal belief of what this is all about. It is the time to come of computing arrival right at you.

So here goes.

Tv Remote Program

Let's start by talking about something that I'm sure every person is well-known with - remote control devices. If you are like me, you have some kind of entertainment center. Mine consists of a television, a cable box, a receiver, a Dvd player, a Blu-ray player, a Dvd recorder, and a Cd player. That adds up to 7 pieces of equipment. Each piece of tool arrived with its own remote control device. This means that I have 7 remote control devices lying on my coffee table, normally in some state of disarray.

Each remote control expedient is set to the same frequency as the engine it controls. Each expedient and its corresponding engine speak the same language. And that is why my television remote has no result on my Blu-ray player or Cd player or cable box.

Each remote control expedient and corresponding engine is a piece of hardware. What makes them work are programmed instructions - software.

So someone came along and figured out how to simplify all this. A universal remote was created that can duplicate or replicate the frequency and language used in each of your remote control devices so that one remote control expedient is all that is needed to make all your machines work. In other words, within that one universal expedient is a virtual television remote control device, a virtual cable box remote control device, a virtual receiver remote control device, a virtual Dvd remote control device, a virtual Blu-ray remote control device, a virtual Dvd recorder remote control device, and a virtual Cd player remote control device.

What are the advantages of this? Well, the first and most definite advantage is that I can now take all those remotes that have been occupying coffee table real estate and put them in a drawer somewhere. I only need the universal remote. Another advantage is that I now don't have to keep a case of batteries in the closet to power all those devices. That saves me some money as I only have to power the universal device. ultimately the amount of money saved will pay for what I spent on the universal device.

In general, virtual means the quality of affecting something without nothing else but being that something. It has come to mean, in modern times, "being in essence or result but not in fact." In the above example, each of the remote control devices appeared to be in the universal controller without nothing else but physically being there. Thus, they were virtualized. They were there in essence but not in fact and each virtual expedient could generate the same result as the real device.

Okay. That is a bedrock belief of what it means to virtualize something. Now let's move it over to the field of computers and networks.

Virtualization and Computers

As a home user, you have a single workstation that, aside from your desk, chair and surrounding work space, consists of hardware (a tower containing a motherboard, a Cpu, one or more hard drives, Ram, a power supply, cooling system, etc.; a monitor; a mouse; Cd/Dvd player; and normally a dedicated printer) plus software (the programming code or instructions that have been installed on the hard drive). All this is made to work by One operating theory or Os (Windows Xp, Vista, Windows 7, Linux, etc.). The Os runs the computer and provides you with an interface with which to issue commands to the computer system. Computer technology, as we have known it, required one Os per computer. And, depending on the tool you use with this workstation, it uses a definite volume of electricity.

One thing is certain, no matter what you use your home computer for, you are only tapping into a very small fraction of what your Cpu is capable of (presuming of procedure that your Cpu isn't some old dinosaur). Processing power has been almost doubling every 18 months. Just think how many times it has doubled in the last 20 years: start with 100 million instructions per second (Mips) and you'll see that in the second 18-month period it would reach 200, in the third 18-month period, 400, in the fourth 18-month period, 800, etc. This gets to be very stratospheric very quickly.

How many Mips are you currently using? Fact: Your hardware is underutilized.

Now, let's move from your home workstation and look at the scene in a company of 20 workstations all connected to servers and shared printers. Like your home workstation, each workstation in the company has its own computer tower, monitor and mouse. Each of these arrangements consumes a definite amount of electricity and that very surely has an impact on the galvanic bill that arrives each month.

Add to these 20 workstations, three servers: (1) a mail server, (2) an applications server, and (3) a file server. Each server runs on one Os and provides services to the workstations. And add further a security appliance, a network switch, a router, and a Nas (network-attached storage) for back-ups for the ever-increasing volume of data off the servers and workstations.

At 50 workstations you might add Another 2-3 servers. At 100 workstations you might add Another 3 on top of the 2-3 you added at 50. Further, as the company's It infrastructure expands (as the company grows), it becomes essential at a definite point to hire an It someone and then Another and another, etc. So you see the It overhead increasing in terms of (a) buying more hardware and software, (b) adding It personnel, and (c) higher energy consumption. And the hardware underutilization also grows.

In a tiny company where the It infrastructure is static (unchanging), virtualization would not be needed. But a company is not a static entity. It grows or it shrinks and efforts to keep it static normally bring about some degree of contraction. So even if you currently don't need to use this tool, it's foremost to have a basal understanding of it for the day when you might need to employ it.

Here's how virtualization works:

Remember the example of the 7 remote control devices being virtualized into the one universal controller? Well, virtualization technology is comprised of specially written software code that does the same thing for servers, desktop computers, applications, storehouse devices and other appliances. I don't want to get into the technical details of how this is done because this article is just about the basal belief of virtualization. Suffice it to say, 7 bodily servers could be consolidated (virtualized) into One bodily server (one Host server instead of 7). In the same way applications can be migrated from their normal residence - a desktop - to a virtualized environment on the virtual server. This means that ultimately the desktop can be supplanted with what is called a "thin client." A thin client (sometimes also called a lean or slim client) is a expedient that can be attached to the back of a monitor and which communicates with the virtual server to open anything application has been premium by the user. The thin client fulfills the original role of the desktop. Thin clients are normally much less costly than a desktop computer. Further, appliances like network-attached storages, security appliances, and a very large host of other appliances can be virtualized onto a server. I'm hoping that you are beginning to get the idea.

The bodily mail server, applications server and file server have been consolidated (virtualized) into one bodily engine - the virtual server. The processing power of the virtual server will be more efficiently harnessed. The workstations have been retired and supplanted with thin clients and there's a lot less iron in this company. There's also less energy consumption. And there can now be a great utilization of It personnel who can now focus more time and concentration to the core company processes of the enterprise.
