2. What is a Grid? Collection of shared resources + infrastructure Collection of shared resources + infrastructure – Cooperating across multiple administrative domains – Secured with PKI (AAA) – Group Collaboration (Virtual Organisations) Compute and/or Data orientated Compute and/or Data orientated – Batch queue, Storage and Worker nodes Infrastructure to support Infrastructure to support – Authentication and Authorisation (VOMS, MYPROXY) – Recognised Trust Authorities (Asia, Europe, US) – Resource discovery (BDII, LFC catalogs) Current Grid projects are the drivers for massive distributed data access over the next few years Current Grid projects are the drivers for massive distributed data access over the next few years
