Deploying a Virtualization Solution Is Never a Quick Fix for Other Problems
During a recent presentation, Gartner analyst Thomas Bittman stated, "There will be more VMs [virtual machines] deployed during 2011 than in 2001 to 2009, combined." Bittman warned that when deploying virtualization, an approach that is "too cold" won't achieve potential savings, while an approach that is "too hot" will lead to virtual server sprawl, along with cost overruns and breakdowns. Simply put, virtual server sprawl will become one of the biggest management issues for modern IT departments. Bittman added that management is the key to maximizing any virtualization deployment within an enterprise data center.The main point of all this is that IT administrators have to show where the savings are. The department must be able to measure those savings, and that requires a management approach that incorporates the ability to monitor and effect change at every level of a virtualization deployment. That means IT departments must be able to quantify loads, capacities, demands and usage, as well as track trends for those elements. The problem, according to Ramanathan, is that most of the management tools included with virtualization products lack critical capabilities, meaning that those seeking holistic management must turn to third-party solutions. "Management is even trickier in some cases," said Ed Laczynski, vice president of cloud strategy and architecture at managed services provider Datapipe. "You are introducing a completely new layer. This is where we think virtualization as a service and infrastructure as a service works for enterprises that don't want to focus on undifferentiated technical chores." Effective management is critical for IT departments that have to show a decent return on the company's investment in the technology.
Srinivas Ramanathan, CEO of eG Innovations, which develops virtualization management software, agreed. He said, "You can quickly negate any savings if you don't measure and manage virtual environments properly."
