  • Common DB shared across clusters
  • At this point, as PAP is not a bottleneck for event processing, do not need more than one PAP per cluster
  • Run PAP on each cluster in active-active vs active-hot vs active-cold
  • Do PAPs manage PDPs across clusters?
    • Would require cross-cluster DMaaP
  • Is there a way to trigger PAPs, in other clusters, to examine the DB?  (DB triggers maybe?)
  • Separate PDP Groups for each cluster?
    • And possibly multiple groups within a cluster, to support multi-tenancy
    • Maybe don't separate them
  • Would clamp talk to all of the PAPs across the clusters?
    • What can kubernetes do to support this?
  • PDPs can be active-active
    • Can deploy same policy across clusters
