The value proposition of Server virtualization and services

In the last major IT buildout, we saw IT organizations adding large numbers of small and medium-sized servers to host their rapidly expanding IT application portfolios.

However, this approach led to very low utilization and higher support costs, the most obvious of which are the acquisition costs associated with needing to overprovision servers.
