CDDLM scenarios (Re: [ogsa-wg] Proposed agenda for Sept. 14th call)

[Hiro Kishimoto]

Hi all,

>>d. The OGSA WG will study the high level scenarios from CDDLM that
>>were the model for the CDDLM specs. Need to reconcile these into the
>>EMS/OGSA space.

I've read the CDDLM foundation document again and tried to correspond
to OGSA-WG's three EMS scenarios. Here is my understandings;

3.1 Web Service in the Grid
    This scenario corresponds to OGSA-WG's server consolidation scenario
    #3. Even it does not refer ACS.

3.2 Commercial Data Center
    Obviously, it corresponds to OGSA-WG's Data Center scenario #2.
    However, CDC scenario does not use advanced reservation and OGSA-WG
    scenario #2 does not cover deployment now.

3.3 IT infrastructure and management
    I think it is too high level compare with OGSA-WG's scenarios.

3.4 Utility computing Model
    This is multiple data center version of CDDLM use case 3.2.
    This scenario also does not have reservation.

3.5 Complex business service
    It is similar to CDDLM scenario 3.1.

3.6 Web Service deployment project.
    It is similar to CDDLM scenario 3.1.

Based on the above study, I think the following two scenarios can
become our starting points;

(a) Web service in the Grid (CDDLM 3.1) and server consolidation
    (OGSA #1)
(b) Commercial Data Center (CDDLM 3.2) and data center scenario
    (OGSA #2)

Your thoughts?
