Advance Reservation Capabilities (ARC) for OCCi
by thomas.roeblitz＠tu-dortmund.de 22 Oct '10

22 Oct '10

Hi All, we currently develop mechanisms for reserving VMs in advance. We thought it would be a welcome addition to the OCCi spec, most likely you're already working on such capabilities. We're happy to join that activity. Philipp and Ramin will attend OGF 30 and may participate in ongoing discussions. Our use cases are (1) set of VMs for a specific time slot, (2) set of VMs for a set of specific time slots, and (3) set of VMs, each VM for a specific duration to be finished before some deadline (global to the set). Related use cases in OCCi [1]: - 2.1 SLA@SOI -- particularly, "scheduling information" - 2.3 Interop w ONE -- particularly, "Quality of Service" - 2.7 Automated Business Continuity ... -- particularly, "Quality of Service" - 2.12 Multiple Allocation -- particularly, "Definition of groups" A possible approach for ARC support would be to associate an attribute 'timespec' with each resource entity (VM) and/or set of resource entities (VMs, didn't check if the current OCCi spec provides that possibility). The timespec's format could be based on the ISO 8601 definition [2]. It would be sufficient for our use cases (except for irregular sets of time slots). Another option could be the webcal specification [3]. Similarly, reservation identifiers could be passed through (e.g., for starting VMs). There may be different options for how actually extending the spec. A subsequent issue is the relationship of reservations and allocations of VMs, e.g. 1:1, 1:N, N:1, N:M. Another aspect would be lifecycle management, particularly how do you manage failures (before and during runtime of a reservation). Think of support for notification and recovery. When we consider reserving VMs from multiple providers, transactional aspects may be of interest as well, e.g., as previously done for Grid computing [4]. But that may be a bit far into the future? What do you think about it ? Anybody else working on reservation of Cloud resources ?

I thought this to be very OCCI-like in implementation, might be of interest to those looking into such aspects... http://flascelles.wordpress.com/2010/10/02/restful-web-services-and-signatur es/ 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).

Feature Freeze for OCCI Core & Model
by alexander.papaspyrou＠tu-dortmund.de 15 Oct '10

15 Oct '10

Folks, since the OCCI core and model seems to have stabilized now (after hard and tempting discussions), I would suggest that we do a _formal feature freeze_ to enforce some stability for the other parts of the OCCI specifications, *effective immediately*. The Feature Freeze is effective immediately. If there are any serious objections against it, please let Thijs know until Monday, October 18, 2010, 12:00pm UTC. Best, Thijs & Alexander

Renaming the "Link" base type
by Ralf Nyren 08 Oct '10

08 Oct '10

Hi, It is easy to confuse the OCCI "Link" base type with HTTP "Link Header" and the general term of linking. Therefore it was proposed during today's conf call to rename the base type "Link" to "ResourceLink". That way we let the name make clear what the Link is used for, i.e. linking Resources. Would appreciate your comments. Deadline is on Friday. regards, Ralf
