Can Nodes from Multiple Locations or Cloud Providers be added in a Single Cluster?

Problem

Is it possible to create a multi-master cluster with master and worker nodes spread in different locations, cloud providers, or data-centers?

Environment

  • Platform9 Managed Kubernetes - All Versions

Answer

  • This is possible with the Bare OS cluster but is not recommended considering the issues related to latency, etcd and Kube.
  • Also, Kube will lose quorum if one of the connections to the data center or regions hosting (n/2)+1 cluster nodes is down.
