Is it possible to have master & infra nodes in a region different than the worker nodes

Solution Verified - Updated -

Environment

  • Red Hat OpenShift Service on AWS (ROSA)
    • 4

Issue

  • Is it possible to configure a ROSA cluster where master & infrastructure nodes are there in one region and the worker nodes in another region ?
  • Does Red Hat recommend the architecture of specific node placement for a ROSA cluster ?

Resolution

  • Having master and infra nodes in a different region other than worker node is not recommended by Red Hat as the nodes in ROSA cluster are in constant communication with each other. Therefore, all the machine pools should be in the same network. For multi-region availability separate clusters should be deployed in each region.
