The collaboration of so many institutions around the world for the same purpose
form a Virtual Organization (VO) which uses Grid in order to gain benefits from
the common use of their resources. In fact, even with the VO, the operation of this
project could be hard due to the enormous size of data that need to be processed.
The partner institutes who are the actors of this scenario - despite their worldwide
distribution - gain through the use of Grid and their collaboration benefits from a
performance that the current technology could not otherwise provide.

5.6.3 The Amazon and Sun (Business Cases 5 and 2)
In this subsection different examples of the same business case - namely 5 - are
merged with examples of business case 2 and are presented together, in order to
demonstrate the relationship between the two distinct business cases and to show
how the same company can be a different actor in each different business case.
Business case 5 of table 5.1 can be characterized as common since big IT compa-
nies that own a large infrastructure follow this business model in order to provide
their under-utilised and/or specially provided computing resources to customers.
