In 2006 IDC released a study showing that the costs associated with data
center management escalate at an alarming rate – in large part because of
rising software management expenses. For users of Linux in the data center,
these costs can be striking, since expenditures for management software can
run four times the cost of procuring the hardware and operating system.
The growing systems management costs underlie a bigger evolution at the heart
of modern data centers. In years past, data centers were predominantly
composed of big iron – mainframes or large Unix computers that could scale
with the addition of a few powerful servers. These servers were part of a
homogeneous operating system environment – and as a result could be managed
centrally, keeping management costs relatively low.
But then Linux exploded on the scene and offered something new for data
