Users can instruct the operator to build a system that includes the provisioning of containers and volumes with FEP installed, and network resources. The resulting system is called a FEPCluster. The FEPCluster can be created a single master server or multi-servers with one master and two replicas. You can choose between synchronous and asynchronous replication replica servers. The default is asynchronous replication.

FEPCluster is composed of the following components:

• FEP server container

  • FEP server

  • Patroni

• FEP backup container

• CR FEPVolume for volumes

• CR FEPUser for database users

• CR FEPConfig for Postgres configuration

• CR FEPCert for secrets such as TLS certificate, keystore passphrase

  
  

The Below diagram depicts a FEPCluster with one Master and one Replica POD.

Users can deploy Pgpool-II for load balancing and connection pooling with FEP pgpool2 container.

Users can deploy multiple FEP pgpool2 Pods in a single deployment to increase availability.
