>>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
