Categories and Collections
by Andy Edmonds 07 Oct '10

07 Oct '10

Hey all, I've placed a write up of how categories and collections related to each other. Also there is how one can interact with collections. I've tried to keep the description as non-rendering-specific as possible. http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/Collections If there are comments etc please annotate the wiki page at the appropriate place or place your questions in the "Open Issues" section.

Initial Authentication Mechanism Discovery Wiki Page
by Edmonds, AndrewX 07 Oct '10

07 Oct '10

Hey all, I've added an initial description of how authentication mechanisms can be discovered. It uses our already defined query interface so is merely but an extension to this feature of OCCI. http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/AuthMechDisco Andy ------------------------------------------------------------- Intel Ireland Limited (Branch) Collinstown Industrial Park, Leixlip, County Kildare, Ireland Registered Number: E902934 This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).

Do we need both collections and templates ?
by Gary Mazz 07 Oct '10

07 Oct '10

Now that we added tags to collections, it allows providers to associate proprietary meta data with a resource. Since templates are collections, templates seem to be redundant. Call for a new construct (template) for describing proprietary aspects of a providers implementation is a practice and shouldn't require a new occi construct. -gary

Scenario Sets
by Edmonds, AndrewX 05 Oct '10

05 Oct '10

I've added 2 scenario sets to the scenario page [1] that I have had hanging about on my filesystem. The renderings are in need of an update due to some changes in core but as they are in the wiki now, it'll be easy to update. http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/ScenarioSet1 http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/ScenarioSet2 Andy [1] http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/ExamplesUseCa seScenarios ------------------------------------------------------------- Intel Ireland Limited (Branch) Collinstown Industrial Park, Leixlip, County Kildare, Ireland Registered Number: E902934 This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).

29 Sep '10

Hey all, I have mentioned on the confcalls that I've sent in a request for the registration of an OCCI group and so IRC channel. The request is still in their queue but for the time being we've a temporary channel on irc.freenode.net called #occi Andy ------------------------------------------------------------- Intel Ireland Limited (Branch) Collinstown Industrial Park, Leixlip, County Kildare, Ireland Registered Number: E902934 This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).

Moving to the Cloud - Establishing a Decision Process
by Drussell4881 23 Sep '10

23 Sep '10

There have been some excellent comments to-date on what we need to consider in “Moving to the Cloud” for the Cloud Computing Use Cases White Paper (http://groups.google.com/group/cloud-computing-use- cases). Rather than trying to put explanations in place for each of the suggested considerations, it is worth stepping back and look at establishing a process on how cloud services could be identified. NOTE: The Cloud Consumer (CIO / CTO / CFO) will want to see a ROI from moving a service to the Cloud and the Cloud Provider needs to make money from hosting the service. Both those thoughts are valid. Therefore, It is important to consider the business implications of moving to the cloud first before applying rules to minimize risk. Bottom line, if moving to the cloud does not have a positive impact on the success of the business, then it's probably not worth doing. Take a look at the following suggestions and let us know if this logic makes sense and identify what you feel may be missing from the following discussion. Step 1 – Identify existing or new processes, services and data as candidates to “Move to the Cloud” Not all processes, services or data are candidates for the Cloud. If we are going to use business criteria to identify cloud candidates, the following are possible examples: - Save money? - Increase flexibility to handle fluctuating volumes ? - Improved customer access / satisfaction ? - Off-load work from existing IT environment ? - Consolidate like work with other enterprises within the cloud? - Other considerations ? If the candidate, either, new or existing meets one or more of the above then that candidate could potentially move to the Cloud. Step 2 – Manage the risks for those candidates to be moved to the cloud. To get through managing the risk and make it easier, one needs a starting point. If one considers the data aspect of the candidate, then hopefully, all the other considerations become dependent on the characteristics of the data to be considered to be moved. Examples of data types are: - Public access (think parts in a catalogue ) - Private access (info that is either confidential or needs to be kept private or both) - Shared data between enterprises - Data that needs to be accessed 7 x 24 - Data that needs to have sub-second access time - Other types of data Once the data step has been considered and applied against the identified candidates from Step 1, it is very important to identify if that candidate can be separated from other processes, services or data from services which are not identified as candidates. If the identified candidate(s) can be executed independently then the risk level can be assigned. As part of assigning the risk level one has to consider the security policies assigned to the data. Other risk considerations are SLA, Single Sign-on capability, availability, disaster recovery, etc. can be determined. (Pull from the list that the group has already created.) As part of validating the risk assessment, one may also want to be able to test the candidate in a Private Cloud environment, ensuring that the security policies established by the enterprise are intact before deploying the service to a Cloud Provider. Step 3 – Metering In parallel to ensuring that the risk issues have been determined and addressed, then comes the cost of doing business in the Cloud based based on data volumes and risk management. For a service in the cloud, a cost factor will be assigned for accessing the data. It is important to understand the cost equation for the data access. The cloud consumer needs to project the average access rates, the peaks and the valleys. By understanding the volume projections and the access patterns, a cost can be estimated. Remember, the CFO does not want any surprises at the end the month or quarter, especially when the cost of running the cloud service exceeds the budgeted amount. The three steps represent an overly simplified approach to identifying the right cloud candidates to migrate to the cloud. If these steps make sense, then we can use these steps as a base. It is important to have a repeatable process to qualify the value and the risk of Moving to the Cloud, otherwise the wrong decision can be easily made. I look forward to your comments as we begin to build the “Moving to the Cloud” portion of the Use Cases White Paper at http://groups.google.com/group/cloud-computing-use-cases. Dave

Update of Core & Models and Infrastructure
by Ralf Nyren 08 Sep '10

08 Sep '10

Hi, I have finished and uploaded a rather significant update of the Core & Models [1] document. The Infrastructure document [2] has been updated accordingly while the HTTP Rendering document is still in the works. The Core & Models changelog: - Updated UML diagram. Fixes the issue with Actions. - Updated and re-structured description/definition of the base types. Please read everything through. - Templates definition added, it is just a Category but without the requirement to be a type construct. - Added full description of the Category base type. - Removed all REST and HTTP stuff. This information will reappear in the HTTP Rendering document. - HTTP related Open Issues will reappear in the HTTP Rendering document. - Extension rules properly defined. - Discovery mechanism from the Core perspective. Hopefully the new version should be a lot more consistent and only address things relevant to the Core specification. The information which was specific to the HTTP rendering will reappear in that document when it is completed. I put some effort into describing how to extend OCCI Core so each base type now has its on subsection describing the rules for domain-specific extensions. Comments welcome. regards, Ralf [1] http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/CoreAndModels [2] http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/Infrastructu…
