TeamQuest Corp. this week published study results that identify three major challenges associated with virtualization and server consolidation according to IT decision makers in North America and Europe.
The three, according to the commissioned study conducted by Forrester Consulting on behalf of TeamQuest in April, are:
* Server size needed to support the virtual containers is difficult to
* Performance and workload of application virtualization candidates is
difficult to assess
* Major performance issues occur at peak times due to resource contention between the containers
Study results show these challenges, initially identified in the Q4 2008 study, have become more pervasive, a likely reflection of the complexity associated with the dynamic nature of virtualization, TeamQuest said.
The ability to dynamically alter the initial resource allocation requires an even more precise view of application performance behavior to avoid contention for physical resources and unexpected performance issues, the firm added.
“Virtualization lowers the amount of hardware required and reduces power consumption to some extent,” said Scott Adams, director of product management with TeamQuest.. “But it also raises management complexity since there is no longer a permanent and exclusive relationship between physical resources and the software that runs on it.”
