Will there be any use of WS?
Make application bend to the user – not
the other way.
Piece of cake to use web forms. But
scientists/users want more than web
forms.
They want to program their applications
as if it were their robot to find and use
services on the grid.

Will there be any use WS?..
Loose Coupling, No hard coding to use.
Service Oriented Architecture
Withstand: S/W Migration, Version
