Grid Architecture
Fabric layer: Provides the resources to which shared access is mediated by Grid protocols.
Connectivity layer: Defines the core communication and authentication protocols required for grid-specific network functions.
Resource layer: Defines protocols, APIs, and SDKs for secure negotiations, initiation, monitoring control, accounting and payment of sharing operations on individual resources.
Collective Layer: Contains protocols and services that capture interactions among a collection of resources.
Application Layer: These are user applications that operate within VO (Virtual Organization ) environment.
