The biggest issue most IT organizations have with virtualization on a daily basis is a general lack of visibility between the applications running on top of a virtual machine and the underlying infrastructure.
A new survey of 750 IT executives conducted by Xangati, a provider of management tools for physical and virtual IT infrastructure, drives this point home, with 73.9 percent saying that understanding the behavior of multi-tier applications in virtual environments was either important or very important.
The biggest issue these IT managers have with virtualization is their limited knowledge of how different tiers of computing interact with each other over the network. Other major concerns were limited knowledge of how databases were interacting with their storage systems and how business logic components were interacting.
A shortage of access to sophisticated virtualization management tools is a big part of the problem. But as David Messina, vice president of marketing for Xangati notes, most of the issues with virtualization stem from a lack of visibility across the virtual and physical infrastructure layers. There are plenty of tools to manage virtual and physical infrastructure, but it's clear that IT organizations need a unified view of both virtual and physical infrastructure in order to correlate where problems may be occurring.
In the absence of such information, virtualization is unfairly blamed for every problem in the enterprise, which in turns contributes to a general stall in virtualization adoption.
Unless properly managed, virtualization can create an impenetrable wall in the enterprise that makes effectively managing IT almost impossible.
