[Openstack] OpenStack conference attendance numbers?

2015-09-09 Thread Preston L. Bannister
On a lighter note... Perhaps I am looking in the wrong places, but I cannot find a list of attendance numbers for the OpenStack biannual conferences. Any pointers? ___ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to

Re: [Openstack] cinder-snapshot -vs- cinder-backup?

2015-02-01 Thread Preston L. Bannister
Depends on your aim. Be aware that the OpenStack community does not really have a good handle on "backup", on efficiency at scale, and the differing levels of service. >From the perspective of building efficient backup at scale, the existing OpenStack APIs make almost no sense. If your deploymen

Re: [Openstack] Scheduled Backup (was Openstack capabilities)

2014-12-27 Thread Preston L. Bannister
Likely as the first part of the problem is as yet unsolved. How do you do backup in OpenStack, efficiently? Schedules are easy. Simple "cron" works. The vendor offering backup could do scheduling. The public cloud providers might want to do their own scheduling. Individual cloud tenants might want

My current choice is to use Redhat's "packstack" on Centos 7 (not earlier). Seems to work rather well, and reflects the larger production environments I have seen (so far). Clearly there is no one answer to this question. :) On Wed, Dec 10, 2014 at 10:44 PM, somshekar kadam wrote: > > I was t

I take issue with choice of words, in your note. The key here is around this statement: Essentially, this means that any token for a particular user can indirectly > be used to perform any action that user is allowed to perform. As we are talking about actions the "user is allowed to perform", t

As a relatively new DevStack / OpenStack developer ... how would we guess usual workflow? :) (I did figure out the local.conf => nova.conf push. The Devstack unstack / rejoin / clean is still slightly foggy.) On Tue, Oct 14, 2014 at 6:31 PM, Dean Troyer wrote: > On Tue, Oct 14, 2014 at 12:14

Re: [Openstack] [Nova] How does/will Openstack handle instance replicas?

2014-09-26 Thread Preston L. Bannister
Yes. Really three(?) different beasts, here. Ephemeral storage is exactly that. It must contain nothing that needs to be preserved. So you can factor this out into three main cases: 1. Instance boots from ephemeral storage. All persistent state is not owned by the instance. 2. Instance boots fr

[Openstack] Backup of cloud applications in OpenStack

2014-08-22 Thread Preston L. Bannister
Was asked at work a few months back to look at backup for OpenStack. To my mind, the end result needed is clear (had some time to think on the subject), and what I see in OpenStack at present - or what is proposed - is not what we need. Wrote on the subject: http://bannister.us/weblog/2014/08/21/

Re: [Openstack] Why doesn't suspend release vCPUs/memory?

2014-06-23 Thread Preston L. Bannister
There is an expectation here. Is it explicitly optioned in the API? Should it be? Should a suspended instance be immediately resumable? If the expectation is that a suspended instance is resumable, then the claim against quota should be preserved, and the current behavior is correct. If the expe
