Real Customer Stories: Rackspace customers suffer for "departmentalization fever"; won't share virtual infra

Well, I didn't hear that from John Engates, who I spoke to a few days back myself. But customers indeed are the ones who are playing really tough. John does have a point about the I/O, security and Performance as well.

I am taking up this initiative myself, within my new employer (AtosOrigin) to have some of these optimization tools as a default design option within our Data Centers.

Anyways here are the stories:

Engates said that in fact security was not a major concern when it came to virtual machines (VMs) - until someone finds a way of tunnelling into the hypervisor. He was clear however to point out that security issues still remain within VMs themselves and that they need to be managed from a security standpoint just like physical boxes.

Rather, his customers were concerned about sharing a physical server because they would not have visibility into what other customers were doing on the hardware.

Since it makes no sense to virtualise an application that hammers the hardware, it's reasonable to assume that most virtualised applications don't generally hog resources. But, if an application in a VM gets hit hard - whether for legitimate reasons or because it's the victim of a DOS attack for example - and then hogs the CPU, storage link or Ethernet ports, all other VMs on that box would be affected. If company A's VM gets hit, company's B's applications slows right down - and there's nothing they can do about it.

The problem is, according to Engates, that there are few if any ways, given the current state of virtualisation technology, to prevent one VM hogging resources, especially I/O or CPU. He said that the tools just aren't there.

Engates acknowledged that the problems Rackspace faces in this regard is similar to that in most organisations, where departments that "own" a server - and are being charged for it - are frequently reluctant to share it with another department in the same company, often for similar reasons. At a recent meeting of IT admins, this issue was voiced as a matter of concern. So it's perhaps hardly surprising that those using managed hosting providers are wary of external organisations.

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…
