Innovation through service oriented computing and web services

As the e-service paradigm becomes popular and more and more applications are developed or deployed as e-services, the need and opportunity for defining composite service become manifest, vendors and consortia are providing models languages and interfaces for describing e-services and making them available to users(1). As well as many researchers and scientists already wrote about the changes that modern technologies could bring to all aspects of our life (aspects that are commercial(2), social or educational), it is commonly observable they are nowaday active, with big companies, developing and expanding the network. It could remain a kind of big data and information '' container '' or it could evolve into a '' tool '', which is particularly used to exchange and communicate, somehow similar to a '' marketplace '', where one can find counterparts suitable to her/his needs. In other words it become an infrastructure capable of serving distributed communities. I here reconsider previous works, to show how the Internet changed till now and how it could face further change, following '' innovation needs ''(3). Services exist since the network itself exists. But the kind of services here under debate are a developed software, with which users may perform a given task using already given resources. So a service-oriented architecture is a way of connecting applications across a network via a common communication protocol(4). This lets developers treat applications as '' network services '', that can be chained together to create a complex business process more quickly. Indeed the paper is mainly about effects IT innovation provides on businesses and marketplace. The aim of the paper is therefore to consider all the cited aspects providing an integrated model and a further contribution to the study. The paper have to show how Internet evolution constitute a technological support for changes occuring in businesses (with a historical background). New technologies differently bring to a different way of managing value chain and internal marketplace but also impact external marketplace. Electronic marketplace become an extension of traditional marketplace and are implicitly bringing a certain automatization to typical processes and negotiation.
