Event Details

As Openstack continues to mature，more and more enterprise chooses Openstack in their IT infrastructure. And more applications migrate to their private OpenStack, which in turn leads to more vms in a single OpenStack cluster than before. To ensure the cluster stability and robustness, those vms should be montiored effectively. In this talk we will give the challenges we meet and how we solve them. Our experience may help those users building their own Openstack cluster in large-scale IT environment.
The Challege we meet:

1) Ceph becomes the bottleneck

2) Redis as incoming storage is ready in master branch

3) Gnocchi api is called too frequently

4) Keystone is under high pressure

5) Performance optimize

In this presentation, we want to share those experiences to users. Some of thoses are solved by optimazing configuration while some need to optimaze in code.
