  1. Industry-Wide System Management Standard Bernd Sint Seminar Grid Computing II WS 2006/07

  2. Introduction Source Merge of Grid and Web [9]

  3. Contents • WSRF and WS-Notification • WS-Transfer and WS-Eventing • WSRF / WS-N vs. WS-T / WS-E • Outlook - The New Standard • WS-RT Demonstration

  4. A typical Web Service Source: A stateless Web Service invocation [1]

  5. Web Service - stateless Source: A stateless Web Service invocation [1]

  6. Web Service - statefull Source: A stateful Web Service invocation [1]

  7. WS + Resource = WS-Resource Source: A WS-Resource [1]

  8. WSRF specifications • WS-ResourceProperties • WS-ResourceLifetime • WS-ServiceGroup • WS-BaseFaults

  9. Related specifications • WS-Notification Allows Web Service to be configured as a Notification Producer, and certain client to be Notification Consumers • WS-Addressing Provides a mechanism to address Web Service Resource: Web Service + Resource as Endpoint Reference

  10. WS-Notification Source: http://www-128.ibm.com/developerworks/xml/library/ws-soa-enter8/

  11. WS-Transfer • XML-based representations of entities using the Web Service infrastructure • Resources, which are entities addressable by an EPR • Resource factories, which are WS that can create a new resource • 4 operations: Create, Delete, Get and Put

  12. WS-Eventing Source: http://www.codeproject.com/useritems/WSEventing.asp

  13. WSRF is more complex WSRF has no „Create“ functionality WS-Eventing has not so much functionality WS-Eventing can only subscribe to Web Services Comparison

  14. Comparison „Hello World“ with no security Source:Testing „Hello World“ with no security [4]

  15. „The“ new Standard • HP, IBM, Intel and Microsoft announced on March 15, 2006 their plans to develop a COMMON SET OF WS SPECIFICATIONS FOR RESOURCES, EVENTS AND MANAGEMENT

  16. Why these four vendors?
