Although EDB Postgres Distributed for Kubernetes (PGD4K) supports architectures spanning multiple Red Hat OpenShift clusters, this document focuses only on elevating the single point of failure of PostgreSQL databases with EDB PG4K to a Red Hat OpenShift cluster, typically equivalent to an entire region in the cloud or a data center in on-premises deployments. The recommendations included in this document serve as a building block for more complex architectures across different Red Hat OpenShift clusters. A separate document covers addressing multiple Red Hat OpenShift clusters.
