Industry-Wide System Management Standard Bernd Sint Seminar Grid Computing II WS 2006/07
Introduction Source Merge of Grid and Web [9]
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
A typical Web Service Source: A stateless Web Service invocation [1]
Web Service - stateless Source: A stateless Web Service invocation [1]
Web Service - statefull Source: A stateful Web Service invocation [1]
WS + Resource = WS-Resource Source: A WS-Resource [1]
WSRF specifications • WS-ResourceProperties • WS-ResourceLifetime • WS-ServiceGroup • WS-BaseFaults
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
WS-Notification Source: http://www-128.ibm.com/developerworks/xml/library/ws-soa-enter8/
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
WS-Eventing Source: http://www.codeproject.com/useritems/WSEventing.asp
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
Comparison „Hello World“ with no security Source:Testing „Hello World“ with no security [4]
„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
