The Costs of Virtualization

Arthur Cole

Virtualization can cut costs, boost operational flexibility and simplify network management, but there are downsides, as this test of the VMware Infrastructure 3 points out.


A chief concern is the performance lag. The ESX server used in the test saw overhead jump from 10 percent to 20 percent, which probably isn't enough to bring you down but will likely show up as a detriment to overall productivity.


Still, more efficient use of hardware resources, and the ability to put off server and storage expansions for a little while at least, are likely to be the primary drivers for investment in virtualization for the foreseeable future.
