EAI with Grid TechnologyEAI with Grid Technology

SOA are the de-facto standard for EAI(WSRF-) Grids are SOAs with extended capabilities

So let's use Grids for EAI!Benefits:

Organizational: New types of collaboration (B2B) and new business models

Technical: More flexibility, virtualisation layer, better resource usage, more dynamic

Goal of BIS-Grid:Proof of Concept, Exemplary Scenarios, D-Grid Integrated Solution

Workflows in Grid ComputingWorkflows in Grid Computing

Workflows in many Grid projects, e.g.:Germany: C3-Grid, InGrid, UNICORE, Fraunhofer Resource Grid

EU (FP5): GRASP, GRIA, GEMMS, OpenMolGrid, GridLab

EU (FP6): A-WARE, Akogrimo, Chemomentum, CoreGRID, DEISA, Diligent, EGEE, ELeGI, K-WF Grid, SIMDAT, UniGrids, SODIUM, TrustCoM

International: Askalon, DAGMan, g-Eclipse, GridANT, Gridbus, GriPhyN, ICENI, JOpera, Karajan, Kepler, TeraGrid, myGrid
