5. ICPS2006, June 6 th 2006, Lyon, France 5 Three Main Questions 1.Are Grid and Pervasive Services related? If yes, how. Example issues –How do you comprehend services’ context in Grids –How does the Grid infrastructure realize the mobility and dynamism of services –What is the role of open standards (web services, OGSA, etc.) here 2.How does Utility fit in the big picture here – examples will be very helpful 3.Is the trio “Grid, Utility and Pervasive Services” the “holy grail” of computing? –If that is the case, what are the key barriers (technical, human, deployment, etc.) that may derail it?
