History
The term ‘Service Oriented Programming" was first published in 2002 by Alberto Sillitti, Tullio Vernazza and Giancarlo Succi in a book called "Software Reuse: Methods, Techniques, and Tools." SOP, as described above, is neither influenced by nor reflects Sillitti, Vernazza and Succi"s use of the term.
Today, the SOP paradigm is in the early stages of mainstream adoption. There are four market drivers fueling this adoption:
- Multi-core Processor Architecture: due to heat dissipation issues with increasing processor clock speeds beyond 4 GHZ, the leading processor vendors such as Intel have turned to multi-core architecture to deliver ever increasing performance. Refer to the article "The Free Lunch Is Over" This change in processor architecture forces a change in the way we develop our software modules and applications: applications must be written for concurrency in order to utilize multi-core processors and writing concurrent programs is a challenging task. SOP provides a built-in opportunity for automated multithreading.
- Application Virtualization: SOP promotes built-in micro control over location transparency of the service constituents of any service module. This results in automatic and granular virtualization of application components (versus an entire application process) across a cluster or grid of SOP runtime platforms.
- Service-oriented architecture (SOA) and demand for integrated and composite applications: in the beginning, the adoption of SOP will follow the adoption curve of SOA with a small lag. This is because services generated through SOA can be easily assembled and consumed through SOP. The more Web services proliferate, the more it makes sense to take advantage of the semantic nature of SOP. On the other hand, since SOA is inherent in SOP, SOP provides a cost-effective way to deliver SOA to mainstream markets.
- Software as a service (SaaS): capabilities of the current SaaS platforms cannot address the customization and integration complexities required by large enterprises. SOP can significantly reduce the complexity of integration and customization. This will drive SOP into the next generation SaaS platforms.

Famous quotes containing the word history:
“There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
—Karl Marx (1818–1883)
“Modern Western thought will pass into history and be incorporated in it, will have its influence and its place, just as our body will pass into the composition of grass, of sheep, of cutlets, and of men. We do not like that kind of immortality, but what is to be done about it?”
—Alexander Herzen (1812–1870)
“Man watches his history on the screen with apathy and an occasional passing flicker of horror or indignation.”
—Conor Cruise O’Brien (b. 1917)
