Introduction
Information technology is a field in which innovation is
constant and relentless, as we have moved over the last 100 years through
mechanical, electromechanical, vacuum tube and discrete transistor to the
integrated circuit of the current paradigm. Moore's Law offers the most widely
recognized evidence of the growth rate of technology; in 1965 Intel's Gordon
Moore predicted that the number of transistors per integrated circuit would
double every couple of years. Moore forecast that this would continue until at
least 1975; in fact it has continued through to today. Storage density offers
another example of this trend; mobile hard disk drive densities have shown
growth rates of 100 per cent per year. There are obstacles to this relentless
progress however; Moore's Law has relied on a manufacturing technique called
scaling in order to shrink transistors, but we are now approaching the limits of
scaling, as key transistor components such as the gate insulator are reaching
physical limits. Components are approaching atomic layers of thickness; further
shrinking would degrade performance. The history of technology indicates,
however, that as each generation of technology reaches its limits, new
breakthroughs are discovered.
This constant technology innovation has exerted a strong pressure
on the costs of physical assets, yet IT spending by businesses continues to
grow. This paradox is rooted in two key factors. First, the physical cost of
assets accounts for a falling proportion of businesses' IT costs; IBM research
indicates that the labour cost of supporting storage systems is approaching
three times the hardware cost. Indirect costs such as helping colleagues
informally can account for 60 per cent of the total cost of ownership for
PCs.
The second reason that IT spending has not fallen in response
to falling physical costs is that the increasing business demands placed upon IT
have matched or exceeded the improvements in technology. Increasingly complex
business processes, globalization and e-business have all driven the demand for
more effective IT implementation and optimization. It is these business demands that account for the
developments in deep computing, pervasive computing, e-sourcing, continuous
operations, bandwidth, universal access and security which are addressed in this
chapter.
