3 Session Agenda OGSA status update Hiro Kishimoto, co-chair Three new OGSA document overview –OGSA Profile Definition 1.0 –OGSA WSRF Base Profile 1.0 Tom Maguire, co-chair –OGSA Roadmap 1.0 Jem Treadwell

4 OGSA Status Update Outline What is OGSA? Progress after GGF13 OGSA future OGSA sessions at GGF14

5 What is OGSA Open service-oriented architecture –Based on Web services –Addressing Grid scenarios Component-oriented architecture –Interchangeable components Meta OS functionalities –Distributed and heterogeneous environment A rendering of these functions –Based on Web service architecture and specifications GGF’s flagship architecture and the blueprint for industry-standard grid computing

6 OGSA Design Philosophy Service Oriented Architecture –Interface Extension (WSDL 2.0 ‘extends’ attribute) –Resources as First Class Entities Expressed as WSRF-Resource Properties –Data type extensibility and introspection –Dynamic service/resource creation and destruction Component-Based –Elements of the Architecture are pluggable Customizable –Support for dynamic, domain specific content,... –Within the same standardized framework

7 Information Services Infrastructure Services Self Mgmt Services Security Services Resource Mgmt Services Execution Mgmt Services Data Services Context Services

9 OGSA Status Update Outline What is OGSA? Progress after GGF13 OGSA future OGSA sessions at GGF14

10 OGSA History ~ 2004 Announced at GGF4 (’02/2) WG created (’02/9) GGF events and 12 more interim F2F meetings 3 regular weekly teleconferences (Mon & Wed *2) > 300 mailing list subscribers Declared as GGF’s flagship architecture at GGF10 (’04/3) OGSA Usecase document publication (’04/11) OGSA document v1 and glossary publication (’05/3)

11 Direction –Focused on high-level abstract architecture document 2004 Dec. F2F meeting in Washington DC –Community needs “implementable specs” –Agree to start OGSA profile development 2005 first half –Mainly focus on low-level “profile” work GGF13 –Spawned 4 WGs (BES, ByteIO, Data, Naming) –3 WGs for service interface development GGF14 –Three documents submitted –SCRM-WG (SDOs collaboration) session –Resource Selection Service WG BoF

12 Newly formed WGs Four WGs proposed at GGF13 are all approved OGSA-Data WG –Describe OGSA data architecture OGSA-ByteIO WG –Define simple byte read & write interface OGSA Basic Execution Service WG –Define simple container interface managing jobs OGSA-Naming WG –Define three-level naming and name resolution interface

13 Three output documents at GGF14 Defining the Grid: A Roadmap for the OGSA –Now in public comment review period (~ July 26) OGSA Profile Definition 1.0 –Submitted to GGF editor OGSA WSRF Basic Profile 1.0 –Close to GGF editor submission –Wait for OASIS WS-Notification Committee Draft vote (July 6)

14 SCRM-WG Standards development organizations Collaboration on networked Resources Management Working Group SDOs collaboration is critical since magnitude and scope of OGSA is far greater than GGF can handle alone Round table style collaboration among SDOs –DMTF, GGF, IETF, ITU-T, OASIS, SNIA, TMF, W3C, … Scope of WG –The standards associated with the management of resources used in a network or individually, by means of structured data standards “Standards landscape document” is first deliverable –Information regarding the definitions, taxonomy and interplay of the various specifications of each respective organization

15 Resource Selection Service WG Key Part of EMS architecture –Develop usecase and service description document –Standardizing Execution Planning Service interface –Standardizing Candidate Set Generator interface Provisioning Deployment Configuration App. Contents Service Information Services Service Container Data Container Accounting Services Execution Planning Services Candidate Set Generator (Work -Resource mapping) Job Manager Reservation RSS BES

16 OGSA™ GGF has filed “OGSA” as trademark and servicemark successfully Trademark –E.g OGSA™ Architecture, OGSA™ Roadmap Servicemark –E.g. OGSA SM Workshop
