Azure.Source - Volume 68

Scale out read-heavy workloads on Azure Database for PostgreSQL with read replicas, which enable continuous, asynchronous replication of data from one Azure Database for PostgreSQL master server to up to five Azure Database for PostgreSQL read replica servers in the same region. Replica servers are read-only except for writes replicated from data changes on the master. Stopping replication to a replica server causes it to become a standalone server that accepts reads and writes. Replicas are new servers that can be managed in similar ways as normal standalone Azure Database for PostgreSQL servers. For each read replica, you are billed for the provisioned compute in vCores and provisioned storage in GB/month.
