Abstract :
The Grid technologies have brought us a set of new concepts such as utility computing, service ondemand, and resource sharing in the business scene as well as many examples of new modes of science. Although for limited applications grids are able to provide production quality of services today, we are still looking for enablers to apply them to a much broader area of use cases. Populating the Internet for personal and business use, it is to say that the Internet technology changes our personal life and business environment in terms of our work style like SOHO, accelerating business speed by easy communication and handy tools, globalization dismissing geographical boundaries and professional borders. However achieving such flexibility and speed in the business, current monolithic IT infrastructure never meets the demand of high agility in business. We take the service oriented architecture (SOA) as one of the key technologies to bridge the gap, but without considering computing resources, SOA will not become a feasible solution. Co-designing SOA for a flexible service building model and IT utility model of payper-use to save TCO, it is the perfect match to produce a future IT infrastructure, that is to say e-Infrastructure."
