The above use cases introduced some of the core scientific and commercial usage patterns for grid computing. After going through the above representative use cases and the functional requirements exhibited by each of them, we can classify them into four categories:
Basic functions
Security functions
Resource management functions
System properties
Discussion of the details of these classifications will be covered when we discuss the platform components . Based on the above functional requirements, Open Grid Service Architecture WG started identifying the platform services and the component model definitions for each of the identified services.
