OGSA Service ModelOGSA Service ModelWeb services are not OGSA services!All OGSA services adhere to specified service interfaces and behaviors (some required and some optional)

Factory, registry, discovery, lifecycle, query service data, notification, reliable invocation

A robust abstract services component model, where resources are rendered as services and are composableReliable and secure preservation of distributed stateSupports dynamic late-binding and creation of distributed resource groups

Grid computing links servers, clients and storage from across the Internet to form virtual server and storage pools which may be dynamically allocated.

Today's Grid software is focused on physical hardware allocation for high performance computing and collaboration, but will evolve to support an e-utility environment for most workload types.

The potential is to extend Grid middleware to seamlessly integrate distributed compute resources with existing IT infrastructures for Commercial Grids.

Virtual Clusters, Storage and Resources

Clusters and Storage

Grid computing initatives will drive standards and software which will enable robust resource sharing and collaboration over the Internet.

A Common Problem: A Common Problem: Distributed ComputingDistributed ComputingWeb services, eLiza and Grid efforts try to solve similar problems in different realms:

Defining an open distributed computing platform.Assuring interoperability.Dealing with heterogeneous platforms, protocols and applications.

GRID is currently focused on Scientific &Technical Computing across organizational boundaries

Distributed Resource Sharing is the key

Web Services initial focus on application integration eLiza focused on commercial IT system infrastructures:

Here, sharing resources is not the issue: Managing them is!Sharing function is not the issue: Building solutions on top is!
