That's the finding of a new survey by Forrester Research, called "What applications are enterprises virtualizing: And what will you virtualize next?"
Forrester discovered that IT managers were happy to put less vital applications on virtual servers – such as web and file server systems, or CRM (customer relationship management) and ERP (enterprise resource planning) applications. However, they baulked at virtualising email, e-commerce, security and other mission-critical applications.
According to the Forrester survey, which questioned 60 enterprise server infrastructure executives and managers, 70 percent planned to consolidate email servers, but just 20 percent intended to use virtualisation to augment that effort.
The same was true for applications supporting security functions. And less than half of those planning to consolidate e-commerce applications expected to use virtualisation.
"Because of high use, email is far more likely to be consolidated onto larger dedicated servers than onto slices of a server – of any size," the report stated.
