An Intro to Software Defined Networking

An Intro to Software Defined Networking

As the old saying goes, if you’re not confused, you are not trying hard enough.  I don’t think I am the only person to feel this way about Software Defined Networking (SDN), one of the latest concepts in infrastructure architecture.  For people like me who come from the other side of the great infrastructure divide (i.e., the…

The Problem With Private Clouds

The Problem With Private Clouds

As cloud implementations mature, I see more and more companies considering the question of whether the private cloud truly adds the kind of value required to “move the needle.”  While private cloud certainly has many advantages over traditional infrastructure delivery methods, to me it is becoming increasing clear that the public cloud is where the true…

Selling the Cloud Migration: Workloads Versus Services

Selling the Cloud Migration: Workloads Versus Services

I have been working with cloud architectures and business cases for some years now, and I find it hard to believe that more organizations have not fully embraced the advantages cloud offers.  I think just about everyone knows the basic value proposition for cloud services, things like provisioning on demand, decreased time to market, flex-up/flex-down pricing,…

The Datacenter Dilemma: Recommendation 1 – Stop Building Datacenters

The Datacenter Dilemma: Recommendation 1 - Stop Building Datacenters

Hopefully, I haven’t angered any of the datacenter technology consultants out there, but for almost every company I have ever encountered, building datacenters is a terrible investment.  Worse, it is a massive gamble with shareholders (or owners) money with almost no chance of a reasonable return and the likelihood of more investment down the road.  Datacenters are…

Death Match in the Making: ITIL vs. DevOps

I remember when I started my career in IT, no one talked about functions and processes much.  I started my career in the United States, where ITIL was not widely adopted until relatively late.  Those times seem innocent and chaotic compared to the more rigorous process orientation most large companies have implemented in the last ten years.  That…

Educating the Next Generation of IT Pros

Educating the Next Generation of IT Pros

Once again, my favorite industry website, Information Week, has an interesting article that I feel deserves a response.  The article is called “The Sorry State of IT Education.”  The author has three recommendations for improving the education of our next generation of IT professionals.  First, ensure that all IT professionals know the basics about how a network or a computer…

The Datacenter Dilemma: Recommendation 5 – Track Capacity and Demand, Don’t Predict

The Datacenter Dilemma: Recommendation 5 - Track Capacity and Demand, Don't Predict

I have worked with a number of IT organizations who engaged in quarterly or semi-annual service reviews with the lines of business.  Generally, this is a very worthwhile engagement, which often included the reviews of project or programs as well as discussions about the service levels the IT organization had achieved.  While I strongly recommend turning these…
