14:01:21 <ttx> Hi amorin !
14:01:44 <ttx> Welcome to the Large Scale SIG meeting
14:02:08 <ttx> Our agenda is at https://etherpad.opendev.org/p/large-scale-sig-meeting
14:02:48 <ttx> While we wait for others I'll talk about my recent visit of OpenStack users in Japan, with an idea of their scale
14:03:28 * amorin cant wait for the numbers
14:04:05 <ttx> KDDI (mobile network) runs their network on OpenSTack, 550k cores
14:04:47 <ttx> LY converged the old LINE and Yahoo Japan clouds into a single env
14:05:26 <ttx> About 110,000 physical servers total
14:06:03 <ttx> want to reach 1 million VMs
14:06:27 <ttx> they run 10,000 hypervisors per region, as we commented recently, using teh HTTP messaging driver
14:06:35 <amorin> nice!
14:06:39 <ttx> they also deploy directly from master
14:06:42 <ttx> no releases
14:06:46 <amorin> do they use nova cells?
14:07:01 <amorin> no releases! thats amazing
14:07:29 <ttx> They upstream all their patches and wait for them to land on master to deploy
14:07:50 <amorin> they are even in advance from upstream master
14:08:14 <ttx> yeah it's all very impressive and a testament to how reliable our CI process and systems have been for them
14:08:25 <ttx> We are trying to get them to talk at the upcoming Summit
14:08:38 <amorin> do they rely on zuul and gerrit?
14:08:47 <amorin> I mean, internally, their own zull and gerrit
14:09:00 <amorin> I would love to have them in paris!
14:09:40 <ttx> Not sure what they use internally to track the patches they upstream
14:09:53 <amorin> is it private or public cloud?
14:10:01 <amorin> LY?
14:10:04 <ttx> We could also have them talk about this "upgradeless cluster" as they call it, in a Large Scale SIG session
14:10:23 <ttx> private (LY Corp = LINE+Yahoo)
14:11:03 <amorin> ack
14:11:05 <ttx> OK back to our regular programming
14:11:20 <ttx> #topic Next Ops Radio Hour June 27

14:13:41 <ttx> This is not going to make a lot of progress over the holidays... We'll reignite conversations after summer.
14:13:56 <ttx> As I said, a LY presentation on Upgradeless clusters could be interesting
