I'm not saying that Climate (now Blazar) would be the
only project involved for managing spot instances. By
looking at a draft a couple of months before, I thought
that this scenario would possibly involve Climate for
best-effort leases (see again the Lease concepts in the
wiki above), but also the Nova scheduler (for accounting
the lease requests) and probably Ceilometer (for the
auditing and metering side).<br>
<br>
Blazar is now in a turn where we're missing contributors
because we are a Stackforge project, so we work with a
minimal bandwidth and we don't have time for
implementing best-effort leases but maybe that's
something we could discuss. If you're willing to
contribute to an Openstack-style project, I'm
personnally thinking Blazar is a good one because of its
little complexity as of now.<br>

<div>I think the current thinking around how to sport spot
instances is somewhat backwards. We should first identify the
user facing requirements (I.E. API changes) then identify the
missing pieces needed to support that API, and lastly figure out
where those missing pieces should live. I don't think we can
say Blazer is the answer without fully understanding the
problem.</div>

My bad, I think you misunderstood me. I just said that part of the
problem can possibly land in Blazar because of Blazar already
implements some concepts close to the spot instances model (what we
call leases, ie. a contract or SLA expressed by a REST API), but I'm
also thinking that it would require other components involved.<br>
<br>
+1 on defining API specs for spot instance model, that's what we
raised during the last Gantt meeting.<br>
