Virtualization – Future of Server Hosting
It crept up on our industry in the last few years and is booming more than ever in 2010. Without a doubt -the latest trend in the IT world is virtualization. We knew it was bound to happen in this fast paced digital race so we at Atum have been preparing. Here’s a quick trend industry report for April 2010 …
IN: VIRTUALIZATION
OUT: INFINITE RACKS OF SMALL SERVERS
What is virtualization?
Despite what science fiction movies told us, virtualization does not refer to living your life through a computerized infinitely young clone (think: Surrogates). Instead it is something much more exciting….
Virtualization refers to the ability to run multiple virtual machines on a single piece of hardware – all independent from its neighbours.
In a virtual environment, servers are known as Virtual Private Servers (VPS) and contain the same features (CPU, network interfaces, storage, operating systems) and functionality as a more costly dedicated server all for a fraction of cost. A VPS includes many benefits such as cost saving, better resource utilization, more reliability, greater flexibility, and increased efficiency. You get more out of your existing resources, reducing datacentre costs, improving your server to admin ratio, increasing hardware availability, and improving security.
How does VPS work?
Let’s try to provide you with a better visual scenario.
Imagine you had two friends.
One – let’s call him Joe – lives in a small student house. Although Joe has his own room, he shares his kitchen and bathroom with other people on same floor. Joe’s neighbours are constantly having parties (especially on weeknights) and he hears everything through the thin walls. He is involved in all their problems and his neighbours often have questionable guests making Joe feel his security is at risk.
Your other friend – Anna – lives in a luxurious house in a safe quiet neighbourhood. The only common area she comes close to sharing with her neighbours is the entrance to her street. She isn’t bothered by her neighbours, even when they have parties, because she can’t hear them through her thick secure walls. She is isolated from all their problems and feels safe in her home.
Now which one would you rather be? Exactly.
Shared and dedicated servers are the same. On a shared server, the operating system and resources are shared, slowing down the server performance or worse requiring it to be shut down while the problem gets fixed.
In contrast, dedicated VPS allows you to do whatever you want with your space. Your neighbours problems are not your concern. It gives you the features and functionality of a physical dedicated without the cost of building and maintaining one. You have complete control of your virtual environment.
Is there a catch?
Does this all seem too good to be true? Well this is one of the few times where something is exactly what it’s made out to be. Only recommendation – make sure to hire experts in virtualization as your VPS provider to handle all your work! Level of expertise plays an integral part in achieving the best for your company.

We couldn’t agree more with the recent increase in this trend…. and same goes for our happy Atum clients.

I’ve used vmware, microsoft, and heard of citrix. All are used for development environments and are very slow for desktop use – VM is definitely useful in a VPS capacity.

Xen is an opensource virtual machine monitor that was purchased by Citrix in 2007. Free always helps when you want to experiment on your own.
Lets me have some fun with this server = house analogy. Yes, the virtual machine provides better privacy and isolation from the neighbours in the same house, but if one tenant set fire to their apartment, the others have to evacuate as well. A server can have dozens of virtual machines running, and if one crashes the server all VMs stop. Fortunately you can get features like virtual machine migration which can automatically migrate these VMs to another server – like a robot automatically grabbing you and all your belongings and putting them in a hotel when the fire alarm goes off.
One more please; not all tenants want to live in shared accommodations, Sick Kids in Toronto reported in this article http://miniurl.com/35554 that not all applications port nicely to a virtual machine environment. This should improve over time as application vendors include VM scenarios in their product verification and improve their test coverage.
