VDI conparision: Which one to choose, VMware, Citrix?

Or should I say is upgrading to Vista worth ab bargain? I have heard of official protest groups in Holland and elsewhere who want to cxontinue working on XP for another few years. Offering a fat GUI OS via VDI conenction broker is not a smart idea. It was never meant to push an elephant through a thin wire.

Anyways the comparison, if its worthy the discussion actually or within the context of a typical thin computing model, is here:

It's important to note that a VDA does all the work on the back-end servers where the VMs run; therefore, to accurately estimate the cost of a VDA, you'll need to take into account the server and virtualization software expenses. Estimating these costs will require walking through a series of calculations, which can be modified for a customer's specific environment. As an example, based on numbers from VMware, let's assume that a server can run six to eight virtual desktops per core, with dual-socket quad-core processors totaling eight cores, yielding 48 to 64 virtual desktops per server for the back-end hardware. If we use VMware's Virtual Desktop Infrastructure (VDI) solution, built on VMware's VI3 (Virtual Infrastructure 3) server virtualization software for our example, the Enterprise license of VI3 is $5,750, so the cost for VI3 is roughly $100 per VM. According to VMware, Virtual Center (VMware's management console) can support 1,000 users per instance for $6,000, which adds only $6 per VM. For connection broker software such as VMware's Virtual Desktop Manager (VDM) or a connection manager from a third party, you should add another $50 per VM. Since storage for the virtual desktop VMs under VMware lives on a SAN, storage costs should be factored into the equation. Depending on implementation, these can be quite high, so let's assume $150 per VM for this example. Prorating the server hardware costs per VM adds roughly $350 to $400 per VM. That brings the estimated total to $700 per VM, excluding the user interface device (since in our example, the user is connecting from the existing PC acting as a thin client). To include thin-client devices for new users, add $150 to $300 per user for just the thin client or as much as $900 for an integrated all-in-one thin client (which includes the monitor and keyboard), bringing the total cost to between $900 and $1,600.

The simplified bottom-line pricing comparison (using the very rough example numbers given here) is this: Upgrading a physical desktop to Vista might cost $300 to $400 (per desktop) in hardware costs and $200 to $300 in software costs, totaling $500 to $700 per physical desktop. Delivering Vista through a virtual desktop architecture (VMware's VDI in this example) and continuing to use existing PCs as rich clients accessing virtual desktops might cost $700 per VM desktop in infrastructure costs and $23 per VM desktop, if using VECD, totaling $723 per virtual desktop.

Redhot Future Of IT Part I :Marketing yourself as IT professional

I had promised about the "RedHot IT Future Series" and so we discuss here how you should market yourself EFFECTIVELY as an IT professional in this new (and dangerous) web age! Web is the place where you're a hero today and villain tomorrow. While there are lots of professionals who are active on the web, not all are enjoying a good reputation as they got "personal" with others and got into a cockfight. The passive IT professional has nothing to lose but nothing to gain at all!

I know "marketing" might seem as a greasy term but the idea is to have the truth about you out there. You know you're a good person and your family knows that you're really smart person but the rest of the world doesn't!

So the question is how do I market myself on the web as a true "nouveau IT professional". A guy who companies will be tempted to pick up the phone as say "Hey, we wanna talk with you. Can you fly over to Palo Alto (or Guatemala or Johan…

Redhot Future Of IT Part 2 :Virtualized Workplaces

Click on the title to hear what I have to say, alternatively click here to listen to what I have to say here.

So what is a virtualized workplace? Does it mean it does not exist? That it's virtual? Well in a certain way YES. This is where the future of our workplace is going to be. Well it is already a reality in some countries.

OK lets start by asking ourselves these questions:
Do you really bond with your colleagues? (think Team cohesiveness)
Do you spend great amount of hours talking about great things that you will do together? (think collaboration)
Do you really feel that you give 100% at work? (think effectiveness)
What do you really miss at your desk? (think personalization)
Is your desk comfortable enough? (Again think optimizing personalization, OK you have done your best to make it your place)Does it really matter to your employer that you are there for him/her? (think commitment)
Or do you get micromanaged over petty issues? (think mismanagement)
Do you see your employees perfor…

A Collection of Threnodies : Part 1

Whale Fall
-----------------

Dress me up in my new threads
clasp my greasy palms
grease my hair
I'm ready for the fall


Watch at all the decadence
watching the avalanche
I'm slipping down
losing my buoyancy


What's become of us
where have we come
this far, this close
close to the doors


I hear them, sublimal chants
I'm on the run
I race through the human sea
I am the king!


I'm the slave
to my own undoings
I'm the jester in my courtyard
We jest as we run


We're strolling on that thin rope
we grope as we rope
we're true heros
we're the survivors


we're the scavengers
we're the friends
we're the lovers
we're the unbred


Soon awaiting the fall
we're lurking on us
we're osedaxing us
we're soon going to be done
we'll soon be arrested
