Re: [openstack-dev] [blazar]: proposal for a new lease type
Hi Lisa, As far as I get the main idea of your blueprint it's something that we've planned to do in the future. So, yes this idea is something that Blazar should do. But the problem is that we have some real-time problems. I mean we are in rename process (yeah, it takes real long time for us) and our devstack job is broken (I tried to fix it, but have some problems with time). If you want to discuss how we, I mean Blazar core-team, and you, team from the Italian National Institute for Nuclear Physics, can collaborate we can discuss it in irc on blazar-channel, I think. We just need to appoint a time slot for that. May be week after summit? If I understand you'll be there this week. Nikolay Starodubtsev Software Engineer Mirantis Inc.

Actually we haven't yet developed that because we'd like to be sure that our proposal is fine with BLAZAR. We already implemented a pluggable advanced scheduler for Nova which addresses the issues we are experiencing with OpenStack in the Italian National Institute for Nuclear Physics. This scheduler named FairShareScheduler is able to make OpenStack more efficient and flexible in terms of resource usage. Of course we wish to integrate our work in OpenStack and so we tried several times to start a discussion and a possible interaction with the OpenStack developers, but it seems to be so difficult to do it. The GANTT people suggested us to refer to BLAZAR because it may have more affinity with our scope. Is it so? Therefore, I would appreciate to know if you may be interested in our proposal.

Re: [openstack-dev] [blazar]: proposal for a new lease type
Hi Sylvain, thanks a lot for your answer. I'd like to extend (if possible) the BLAZAR's list of the supported lease types by adding a new one which covers a specific use case which, it seems, it is not yet supported by BLAZAR. You know, In OpenStack every project has a granted fixed quota which cannot be extended dynamically. This implies that a project cannot allocate unused resources assigned to different projects. The idea is to lease such unused resources just for a limited duration time (e.g. from few hours to 1 day). Suppose the project A has consumed all own assigned resources while the project B, in the current time, has several available resources. B may offer its own resources to A just for a limited and well known time duration (i.e. not forever) so that in the future it can claim, if needed, the available resources belonging to A (or other projects). This is a fair-share mechanism which guarantees the resources usage is equally distributed among users and projects by considering the portion of the resources allocated to them (i.e. share) and the resources already consumed. Please remark the share is a different concept than quota in the cloud terminology. You can consider this proposal as a way to update dynamically the quotas by considering the historical usage of each project. This approach should make OpenStack very efficient in terms of resource utilization. About the blueprint I will try to create a new one. Thanks again.

Currently OpenStack allows just a static partitioning model where the resource allocation to the user teams (i.e. the projects) can be done only by considering fixed quotas which cannot be exceeded even if there are unused resources (but) assigned to different projects. We studied the available BLAZAR's documentation and, in agreement with Tim Bell (who is responsible the OpenStack cloud project at CERN), we think this issue could be addressed within your framework. Please find attached a document that describes our use cases (actually we think that many other environments have to deal with the same problems) and how they could be managed in BLAZAR, by defining a new lease type (i.e. fairShare lease) to be considered as extension of the list of the already supported lease types. I would then be happy to discuss these ideas with you. Thanks in advance, Lisa Hi Lisa, Glad to see you're interested in Blazar. I tried to go thru your proposal, but could you please post the main concepts of what you plan to add into an etherpad and create a blueprint [1] mapped to it so we could discuss on the implementation ? Of course, don't hesitate to ping me or the blazar community in #openstack-blazar if you need help with the process or the current Blazar design.
