Preface<br />
<strong>and</strong> nearly a third of growth the follow<strong>in</strong>g year.” 1 This leaves IDC with no<br />
doubt that there is a fundamental shift toward cloud comput<strong>in</strong>g as a delivery<br />
mechanism <strong>and</strong> toward its use with<strong>in</strong> the notion of <strong>SOA</strong> as an approach to<br />
marry cloud comput<strong>in</strong>g with the enterprise.<br />
Moreover, a recent Gartner report shows global revenue from cloud<br />
comput<strong>in</strong>g will top $150 billion by 2013. 2 This projection <strong>in</strong>cludes revenue<br />
generated by the shift from on-premise to cloud-based providers as well as<br />
by the plann<strong>in</strong>g <strong>and</strong> architecture beh<strong>in</strong>d the shift.<br />
What is caus<strong>in</strong>g this shift There are five primary drivers:<br />
1. Purchasers believe that the current cost of traditional enterprise software<br />
is disproportionate to the value it creates.<br />
2. In these budget-conscious times, there is <strong>in</strong>tense pressure to reduce the<br />
cost of acquisition <strong>and</strong> ma<strong>in</strong>tenance of software solutions (the ongo<strong>in</strong>g<br />
support <strong>and</strong> ma<strong>in</strong>tenance of solutions can often be four times the orig<strong>in</strong>al<br />
capital cost).<br />
3. Organizations are striv<strong>in</strong>g to reduce risk, <strong>and</strong> they want a far more tangible<br />
relationship between software’s benefit <strong>and</strong> cost.<br />
4. The drive for reduced risk dem<strong>and</strong>s a much greater predictability of the<br />
runn<strong>in</strong>g costs of the organization’s software solutions.<br />
5. The value of solutions is no longer determ<strong>in</strong>ed by the functionality available<br />
(<strong>in</strong> fact, most organizations use only a small subset of the functions<br />
available <strong>in</strong> their software products) but by the feel<strong>in</strong>gs <strong>and</strong> experiences<br />
of the users <strong>in</strong> the way that they use <strong>and</strong> <strong>in</strong>teract with the solution.<br />
At the same time, enterprises are turn<strong>in</strong>g to <strong>SOA</strong>s to provide a platform<br />
for the use of cloud-delivered services <strong>and</strong> l<strong>in</strong>ks to the emerg<strong>in</strong>g Web, even<br />
through the ad hoc notion of mash-ups. The movement toward <strong>SOA</strong> is well<br />
documented, like cloud comput<strong>in</strong>g, <strong>and</strong> is be<strong>in</strong>g driven faster by the emerg<strong>in</strong>g<br />
service-oriented resources with<strong>in</strong> the clouds.<br />
