explain in your own words the concept of virtualisation? How does it work and what software solutions exist?
also why so system adminstrators often aim to virtualise services today?
Virtualization is about sharing of physical resources.
When computers were less powerful in older days, they could not perform multiple functions. All the resources of the computer is required to perform a single task. Compared with today’s computers, they were lumbering dinosaurs.
Nowadays, computers can perform several tasks at the same time. Multiple processes run in the background. And with technological innovation and advancements in manufacturing, costs are also droppping.
Costs of components are not linear. The price of a 80 GB hard drive is not twice that of 40 GB. Purchasing 2 40 GB hard drives costs more than a 80 or 120 GB hard drive. It is the same with CPUs and memory modules.
Using virtualization, a 120 GB hard drive could shared by 2 separate computers. However, this is different from logical partitioning. Other components, such as the CPU and memory could be virtualized as well.
Using virtualization, a physical PC with a single CPU could be ‘made’ into 2 PCs with their own separate processing, memory and storage capacities. It is as if there are 2 PCs even though physcially there is actually only 1.
For example, a PC with a P4 CPU, 1 GB RAM and 120 GB hard drive could be virtualized into a PC using 60% of CPU processing, 512 MB memory and 80 GB hard drive, and another PC using 40% of CPU processing, 512 MB memory and 40 GB hard drive. A 3rd PC could even be virtualized if want to — just reduce the capabilities of the other 2.
Virtualization is used extensively for servers because rack space is expensive. With virtualization, the physical footprint is reduced significantly while retaining all the functionalities that are needed.
No longer system administrators need to run around to manage multiple servers. Multiple servers have been virtualized from a single powerful server. They only need to switch from one virtual server to another, all at the same spot.
Virtual PC and VMWare are 2 of the more popular virtualization software available today. There are also open-source virtualization software, such as Xen.
Think of it as one step further than emulation of a computer, it is a computer-in-computer at full speed; I’m not sure which software is a "virtualizing" solution.

I agree, saving money on the web or in true life is an individual of the most crucial factors correct now. With the way the economy, position situation, fuel selling prices and housing sector are everybody is hoping to save a greenback the following and there. I believe that how to save funds and how to be a much better shopper should be a class taught in superior school. So that kids can have an even chance and understand what takes place to money when they have to pay their very own expenses.
My programmer is trying to convince me to move to .net from PHP. I have always disliked the idea because of the expenses. But he’s tryiong none the less. I’ve been using WordPress on a number of websites for about a year and am nervous about switching to another platform. I have heard excellent things about blogengine.net. Is there a way I can import all my wordpress posts into it? Any help would be greatly appreciated!
As soon as I came over to this post I can only look at part of it, is this my web internet browser or the internet website? Should I reboot?
