6. What Is Vega? Grid related research thrust (brand) at ICT since 1999 Founded by MOST, CAS, NSFC, industryPeople Grid system software (GOS) 40 Information Grid software (VIG) 10 Service Grid software (VINCA) 30 Basic research and semantic grid (Vega-KG) 30 Share common philosophy VEGA110 –Versatile Services –Enabling Intelligence –Global Uniformity –Autonomous Control Vega Grid Inc. established in 2004 Software versions2000 20032005 GOS (started in 1999)0.51.02.0 VIG (started in 1999) 0.61.02.0 VINCA (started in 2002) 1.02.0 Resources GOS VIG VINCA Apps Ad hocGT3WS-I

12. Vega GOS

13. Vega GOS and OGSA V1.0 Vega is an implementation of (part of) OGSA Vega would like to contribute to OGSA After implementation and testing (running codes) Loose coupling Partner with other groups Focus on 4 key issues and aim at minimal common requirements Naming, Process/States, VO, Programming Vega complements existing grid projects Focus on implementation architecture, not protocols/services Use computer systems approach, not middleware or network Utilize existing software At Vega GOS kernel level –Apache; OMII, GT4; Commercial As services At Vega GOS application level

14. Security in Vega GOS End-to-End From user log-on to physical resource execution Details are hidden from user/developer Based on WS-Security Cert based authentication; Token based authorization & AC; signature Web uCert Portal/Server uid/pass Grip Container Agora pCert Phy SvcPhy SVC pCert uTK pCert uTK pCert uTK pCert uTK UserResAA uTK Other Client pCert uCert

15. Naming in OGSA and Vega GOS Vega matches OGSA 3-level naming convention OGSA Human-OrientedAbstractAddress Vega (EVP) EffectiveVirtualPhysical OGSA Naming specification must include Precise definitions and axioms Syntax and semantics (rough consensus) Who provides, uses, and maintains such names Scoping and name/address space Full Lifecycle Mapping, resolution, binding Exception handling Provision for resources

16. VO in OGSA and Vega GOS There is no precise definition of VO in OGSA Agora is a concrete example of VO (community) Agora has a precise definition, and it holds Subjects, objects, context/policies information Agora-related system services Agora is persistent and “static” Application programmer knows the agora concept, but agora does not appear in app codes

17. Process/States in OGSA and Vega GOS There is no process concept in OGSA 1.0 Grip is distributed process in grids environment A runtime construct representing a subject (a grid user running a grid application) to access and utilize objects (grid resources and services) Classification of “states” Session related Application logic specific Grid system related Resource related Service specific Grip

18. Core and Kernel Put It Together Web Grip User, App Logic Address Space, States Agora Policies: Security and Selection Phy SvcPhy SVC Other Client System Services Resource Services UI and Utility Tools Common Supports not per-service or per-application codes 120 KLOC Follow the E2E and KISS principles Loose coupling; Hide details, reduce coding; Try to minimize abstractions 4 abstractions: User, (Effective) Service, Grip, Agora 5 API “functions”

21. Summary Grid activities in China are still growing CGSP started development in 2004 extends WSRF (GT 3.9), will release V1.0 this year Vega started in 1999 China apps driven, while learning from international community Will release V2.0 in June 2005 Based on WS-I and uses a computer systems approach Vega and OGSA Partner with OGSA-UK Use OMII as a kernel and system services Naming (EVP), Grip, and Agora
