- 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
- How should the consolidated health check work with multiple clusters? Query a PAP in each cluster? Query one single PAP?
- The additional services (e.g., A&AI, DMaaP) may be available in one cluster, but not the other. How would that be reported?
