Today is a very exciting day for me. After many months of blood, sweat, and tears, today we are finally launching a brand new book that I co-wrote (alongside a couple of amazing people – Kurt Milne and Jeanne Morain),…

Private cloud not necessary for enterprises, analyst says
In a recent article on IT World Canada, Selena Mann (no relation) talks about the need for private and public cloud, and whether enterprises really need a private cloud. She also highlights the advice in my new book, ‘Visible Ops…
Public Cloud Computing is NOT For Everyone
Without pointing any fingers, there seems to be a persistent refrain from some public cloud computing proponents that says, ‘If you are running your own IT, then you are doing it wrong’. This attitude fails to account for the magnitude…
How Do You Measure ‘Value’ in IT Innovation?
I recently met with a number of CIOs from large enterprises and discussed, among many other things, what the notion of ‘value’ really means to the modern CIO. As a marketer, I was very interested to talk about this topic, …
The Cost of Innovation in Virtualization and Cloud?
I was pointed the other day to a chart on the Business Insider ‘Chart of the Day’ (@chartoftheday) showing the R&D expenditures for a handful of tech companies, evidence of Apple’s supposedly superior ‘innovation’ compared to four apparently randomly chosen…
Mainframe as an Enterprise Desktop Virtualization Server?
In my last blog, I talked about the idea of a ‘software mainframe’, and how – if that term really means anything – IBM could actually be a serious threat to VMware (and the Virtual Computing Environment coalition of VMware/Cisco/EMC)…
“Software Mainframe” – a Poor Analogy for Virtualization
IT loves analogies. Seriously, will the computer-as-a-car analogy ever die (please)? It has been over 10 years since we first heard jokes about if Microsoft built cars: At a computer expo (COMDEX) Bill Gates reportedly compared the computer industry with…
VM Stall – More Than Four Reasons
I recently saw a great article in IT World Canada titled “Virtual stall: What it is and why you have it,” written by Jay Litkey, that took up my idea of VM stall, which I first came up with in…
Top Ways to Start and Expand Your Virtualization Deployments
Last week I spoke with Pam Baker, a writer with CIO Update, for an article titled The Top 5 Places to Use Virtualization. As you would expect from an experienced professional like Pam, it was a great article, with solid…
Cloud Computing in the Public Sector
If there was still any doubt about the real world use cases for cloud computing, the US Federal Government last week published a 38-page report entitled “State of Public Sector Cloud Computing†(link to PDF at CIO.gov). Attributed to the…
Is ‘VM Stall’ the Next Big Virtualization Challenge?
There appears to be a challenger to ‘VM sprawl’ as the scourge of virtualization success – a problem I call ‘VM stall’.
We know about ‘VM sprawl’ – because new virtual machines are so easy to deploy, organizations can end up with more VMs that they can handle, or even use. This has the potential to cause severe problems to availability, performance, compliance, costs, security, and more.
However, I am seeing more and more evidence of this new phenomenon I think of as ‘VM stall’ – the tendency for virtualization deployments to stall once the ‘low-hanging fruit’ has been converted (typically around 20-30% of servers).
I think it happens more or less like this…
