But virtualize with care, cautions David Marshall, author of the InfoWorld Virtualization Report. David cites a recent report from Gartner, stating that when companies adopt server virtualization, they overlook many security issues, plus the proper tools and technologies for addressing security concerns range from immature to non-existent.

Yager expects it will go down — with time, and the performance benefits may well be worth the investment, depending, of course, on your processing demands.
