>>FUTUREKey Trends and Implied Needs
IT Infrastructure trends with material implications for management
Source: IDC Server Virtualization Forecast 2005-2012> Consolidation suppressing physical growth, but total OS instances (i.e., physical+virtual) still growing rapidly
> Broadening of IT applications (e.g., collaboration, VOIP, mobile workforce, etc.) over time
> Users consumer expectations are beginning to define expectations of corporate IT
Need for management to scale – multi-instance, one-to-many, automation, service enablement, etc.
Source: US Government Bureau of Labor and Statistics> Overall demand for IT
resources trending up, but not keeping up with rate of server growth
> Difficulty finding, training and retaining qualified IT staff
> Ongoing pressure on IT to suppress labor costs (i.e., do more with less)
Need to drive greater IT efficiency – enable IT department to manage many more servers with fewer staff
Growing Complexity Admin Base not Keeping Pace
Source: Higher Education Research Institute Survey, UCLA> Less interest in pursuing
Computer Science education> Smaller echo generation as
baby boomers retire> Lower skill set and
experience in incoming job candidates requires designing for a less skilled target
Need to simplify/streamline management – making features more accessible to targeted administrators
Smaller Pool of Talent
Management Landscape
Key considerations:> Easy to use AND Flexible> Consistent and discoverable> Fast and responsive
