Most Kubernetes clusters in the cloud (73%) are built on top of managed distributions from the hyperscalers like AWS Elastic Kubernetes Service (EKS), Azure Kubernetes Service (AKS), or Google Kubernetes Engine (GKE). Accordingly, the remaining 27% of clusters are self-managed by the customer on cloud virtual machines.

In order to work around this, administrators have to deploy a proxy layer on the server-side. The popular choices are DNS mapping, virtual IP mapping, PgPool and HAProxy. When a PostgreSQL master fails, one of the standby servers needs to be elected to master. Why not have this built it into the server?
