There are very many different communities involved in IT ranging from those on the sharp-end user side of things to the many more engaged in the vendor and channel. Plus of course several different groups, including analysts like myself, that sit somewhere between the two. As with life everywhere else, all of these different groups of people have their own goals and drivers. One of the many problems for these numerous interrelated communes is that quite often the inter-communications between them happen at so many different levels and at vastly conflicting rates that misunderstanding and confusion is almost guaranteed. It is my firm belief that the term “Virtualization”, along with “Green IT”, is now suffering from garbled communications initiated by certain elements of the vendor community.
Those selling solutions, or more accurately, those marketing IT solutions often choose to make products sound new and exciting. Quite why they do so has often puzzled me since I, as a former IT manager, have always been highly skeptical of anything really new as it usually means trouble. However, when it comes to the crazy, and slightly strange, world of Virtualization, things appear to be wild, and certainly subject to more than a little hype. What is certain though is that virtualization really can deliver benefits to both IT and the greater business. What is far less certain is why everyone appears to think that Virtualization is new?
It is fair to say that today Virtualization has become the shorthand that is used to describe a number of logically similar technologies. In the server space this idea is nothing new as the Mainframe has long boasted the ability to run “virtual” machines, each of which operates as if it were the only system running on the hardware when the reality is quite the opposite. Large Unix servers started to offer a range of similar capabilities several years ago. It is really only the so called “industry standard” servers based around Intel and AMD processors that are relatively new entrants into the server virtualization game. However, there are huge numbers of these platforms, many of which are managed by administrators who might never have encountered either the Mainframe or Unix variants of virtualization, so perhaps it would be unfair to be too harsh on those vendors who market server virtualization as if it is something brand new.
In IT, as in most walks of life, very few developments are truly revolutionary and absolutely new. Most ideas grow up over time before really springing to the front of mind with a vengeance. Server virtualization has grown up over the years, especially on the Mainframe, and those systems that deliver virtual functionality to Intel / AMD systems are delivering value. But, and it is a big but, the efforts of those marketing virtualization are not always working effectively. In my conversations with IT professionals it is becoming clear that the hype and at times exaggerated claims that marketing folk make and the very inexact use of language employed around Virtualization are succeeding in raising not only levels of awareness but also of creating confusion in the minds of some IT administrators. The same could also be said to apply to storage virtualization marketing.
It would be good if the industry could take a little time to define a number of terms more accurately to help remove the smog that is building around Virtualization systems. Gaining widespread attention is good but creating confusion, and perhaps building unachievable expectations could slow adoption of these often valuable solutions.
