How often do you have sudden host failures? Especially if you use a half-decent server with redundant components for the DB node? Once in maybe 10 years?

- dmlittle 1y agoThe node failure rate is much higher than that. On a 1M node cluster of cloud-managed instances (AWS, GCP, Azure, etc.) you'd likely see failures a few times a month, if not more.
- cyberax 1y agoYep. And the chances that the DB node with the control plane fails are therefore less than one in ten thousand.
- rixed 1y agoIt's not about failure, it's about servicing the host running etcd or the network around it.
