NetIQ Survey: IT Managers highlights lack of planning could impact on cost savings

July 2008 by NetIQ

A recent survey conducted by NetIQ, has revealed that a high proportion of organisations have no processes in place to monitor the impact of moving to a virtualised environment on end user response time of critical applications.

The survey of 102 IT managers across Europe has revealed that 64% are not presently using any tools to proactively gauge end user response time before and after the migration to a virtualised environment. These findings come as IDC recently reported that the pace of adoption of virtualised servers is "incredibly rapid" in organisations that are using virtualisation, and that 35 per cent of servers deployed in 2007 were virtual. IDC also reported that 52 per cent of servers deployed in 2008 are expected to be virtual.*

NetIQ’s survey reveals that, in the UK, alone, 71% of respondents have no measures in place to monitor end user performance before and after the migration to a virtual environment and just 15% of UK managers were actively considering a solution that would enable them to do this. Nearly a third of all UK respondents are only monitoring hardware performance and availability, rather than applications or OS, in the virtual infrastructure.

The survey also reveals that 90% of all UK respondents cited cost savings as the key driver for the move to a virtual environment, however, as Simon Ashford, Technical specialist of NetIQ warns, more planning and monitoring is needed if these potential savings are to be realised.

“Virtualisation is causing a big buzz with enterprises and can offer huge benefits in terms of cost savings and enabling a more efficient use of resources. However, these findings reveal that more needs to be done to monitor the impact of migration on end user application response time otherwise any potential costs savings could be negated. What happens when a server is under heavy usage or pushed to the limits of its performance? A large proportion of organisations would be unable to measure any potential performance degradation which could be incredibly costly in terms of a user’s productivity.” He added, ”The virtual environment should provide the same if not greater levels of performance, availability and security as the physical environment – yet stringent planning and careful phasing are essential to evaluating project success and avoiding any potential performance pitfalls.“
