Hi.

Quick update is 1000 nodes and 7 million reqs/sec :) - and the number of requests should be higher but we had some internal issues. We have a submission for barcelona to provide a lot more details.

But a couple questions came during the exercise:

1. Do we really need a volume in the VMs? On large clusters this is a burden, and local storage only should be enough?

2. We observe a significant delay (~10min, which is half the total time to deploy the cluster) on heat when it seems to be crunching the kube_minions nested stacks. Once it's done, it still adds new stacks gradually, so it doesn't look like it precomputed all the info in advance

Anyone tried to scale Heat to stacks this size? We end up with a stack with:
* 1000 nested stacks (depth 2)
* 22000 resources
* 47008 events

And already changed most of the timeout/retrial values for rpc to get this working.

This delay is already visible in clusters of 512 nodes, but 40% of the time in 1000 nodes seems like something we could improve. Any hints on Heat configuration optimizations for large stacks very welcome.

Cheers,
  Ricardo

Hi.

Just thought the Magnum team would be happy to hear :)

We had access to some hardware the last couple days, and tried some
tests with Magnum and Kubernetes - following an original blog post
from the kubernetes team.

Got a 200 node kubernetes bay (800 cores) reaching 2 million requests / sec.

Check here for some details:
https://openstack-in-production.blogspot.ch/2016/06/scaling-magnum-and-kubernetes-2-million.html

We'll try bigger in a couple weeks, also using the Rally work from
Winnie, Ton and Spyros to see where it breaks. Already identified a
couple issues, will add bugs or push patches for those. If you have
ideas or suggestions for the next tests let us know.

Magnum is looking pretty good!

Cheers,
Ricardo
