1. September, 2004 CMM-WG presentation1 I acknowledge that participation in GGF is subject to the GGF Intellectual Property Policy. Intellectual Property Notices Note Well: All statements related to the activities of the GGF and addressed to the GGF are subject to all provisions of Section 17 of GFD-C.1 (.pdf), which grants to the GGF and its participants certain licenses and rights in such statements. Such statements include verbal statements in GGF meetings, as well as written and electronic communications made at any time or place, which are addressed to: the GGF plenary session, any GGF working group or portion thereof, the GFSG, or any member thereof on behalf of the GFSG, the GFAC, or any member thereof on behalf of the GFAC, any GGF mailing list, including any working group or research group list, or any other list functioning under GGF auspices, the GFD Editor or the GWD process. Statements made outside of a GGF meeting, mailing list or other function, that are clearly not intended to be input to an GGF activity, group or function, are not subject to these provisions. Excerpt from Section 17 of GFD-C.1 Where the GFSG knows of rights, or claimed rights, the GGF secretariat shall attempt to obtain from the claimant of such rights, a written assurance that upon approval by the GFSG of the relevant GGF document(s), any party will be able to obtain the right to implement, use and distribute the technology or works when implementing, using or distributing technology based upon the specific specification(s) under openly specified, reasonable, non- discriminatory terms. The working group or research group proposing the use of the technology with respect to which the proprietary rights are claimed may assist the GGF secretariat in this effort. The results of this procedure shall not affect advancement of document, except that the GFSG may defer approval where a delay may facilitate the obtaining of such assurances. The results will, however, be recorded by the GGF Secretariat, and made available. The GFSG may also direct that a summary of the results be included in any GFD published containing the specification.

3. September, 2004 CMM-WG presentation3 Outline 2. Free discussion 1. Background, status and future work

4. September, 2004 CMM-WG presentation4 CMM-WG Background GGF8: WG born to do base manageability functionality for OGSA GGF9: Original work moved to OASIS WSDM –Started gap analysis (what is missing on manageability in OGSA, what should be done) GGF10: Presented management framework and glossary for OGSA GGF11: Completed the gap analysis

5. September, 2004 CMM-WG presentation5 CMM-WG Current Status GGF12: Informational document submitted to GGF editor –Endless thanks to Jem and Latha for final review –Will soon enter the 30-day public comment period –Please read It’s a part of OGSA (full version of what went in OGSA v1 document) Many definitions, policies, etc. not yet divulgated enough in GGF (or even in OGSA-WG) –Please make comments (good or bad, technical or not) in the GGF tracker

6. September, 2004 CMM-WG presentation6 Future Work Continue current work as OGSA-WG design team –Support the design of management and manageability in OGSA Liaison work with other standards bodies and GGF WGs Industry- Wide Mgmt Model OASIS Mgmt Web Services W3C Web Services Arch and Technologies GGF Resource Sharing and Provisioning (Model and Services) SNIA Storage Networking DMTF Model Unification and Distributed Mgmt Infrastructure Other Mgmt Stds Orgs Figure from GGF-DMTF work register

7. September, 2004 CMM-WG presentation7 Outline 2. Free discussion 1. Background, status and future work

8. September, 2004 CMM-WG presentation8 Examples of Discussion Topics Naming issue Operational state diagram OGSA use case / scenario –How does OGSA-EMS utilize WSDM? –How does data service utilize WSDM? Resource models (Only CIM? What else? How do they fit?) Events (any news from WSDM?)

9. September, 2004 CMM-WG presentation9 Backup Slides

10. September, 2004 CMM-WG presentation10 Resource Management in OGSA Management of the Grid resources –High-level resource management functionality –E.g., discovery, resource reservation, provisioning, monitoring and control Management of the OGSA infrastructure –Services that compose OGSA are managed resources –E.g. monitoring of a registry, of caching and replication Management of the resources themselves –E.g., rebooting a host, or setting VLANs on a network switch –Mostly out of scope of OGSA

11. September, 2004 CMM-WG presentation11 Resource Models Many models exist –CIM, MIBs (SNMP), JSR77 (JMX), etc. –Resource descriptions contain implicit models, e.g.: Brokering, scheduling, job submission (Unicore Resource Schema, GLUE schema, GRIP, etc.) Deployment Metering Models have semantic and rendering Many models will be used simultaneously in a Grid –Need to coordinate semantics

12. September, 2004 CMM-WG presentation12 OGSA’s Need: a Common Framework The OGSA-WG needs a common framework that meets the needs of Grid computing and distributed systems management: –Resource models (semantics) –Representation of and access to manageability (renderings) Many pieces already exist –Don’t define “yet another” model. Use, compose and extend what exists. –Some (or most) of work done outside OGSA-WG But which pieces do we need? Do they fit together? How?

13. September, 2004 CMM-WG presentation13 Moving forward How to move this work forward is still to be discussed at the OGSA-WG Jay’s proposal: –Lay out high-level requirements on entities and functional capabilities until GGF12 –Survey current activities and determine which can be depended on, based on technical capabilities, accommodating changes, schedule –Identify a “path forward” that can be agreed by all Fred’s opinion: –Collaborate with our partners from the start

14. September, 2004 CMM-WG presentation14 OGSA Management Framework (1) OGSA is composed of several capabilities –Provide high-level resource management functionality (resource reservation, deployment, monitoring, etc.) Data services Domain-specific capabilities OGSA capabilities Security services Execution mgmt. svc. Resources Infrastructure services

15. September, 2004 CMM-WG presentation15 OGSA Management Framework (2) Capabilities use and manage resources to do work –Native manageability (reboot, set VLAN, etc.) –Native interfaces (CIM, SNMP, proprietary, etc.) Data services Domain-specific capabilities OGSA capabilities Security services Execution mgmt. svc. Resources Infrastructure services

16. September, 2004 CMM-WG presentation16 OGSA Management Framework (3) Infrastructure services show resources as services –Use Web services means for discovery, access, etc. –Provide common framework with basic functionality Data services Domain-specific capabilities OGSA capabilities Security services Execution mgmt. svc. Resources WSRF, WSDM

17. September, 2004 CMM-WG presentation17 What is WSDM? (What was CMM?) OASIS Web Services Distributed Management TC –Management using Web services (MUWS) –Management of Web Services (MOWS) MUWS provides: –a uniform, WSRF-based way to access native manageability of various types of resources –A set of functionalities that are of broad and general use for management, e.g.: Metrics (collected values) Resource states Relationships among resources MOWS provides manageability for Web services
