Network and clusters in Managed Service for PostgreSQL
When creating a PostgreSQL cluster, you can:
-
Specify a network for the entire cluster.
-
Specify subnets for each host in the cluster.
-
Request public access to connect to the cluster from outside Nebius AI.
You can create a cluster without specifying any subnets for the hosts if the availability zone selected for each host contains exactly one subnet of the cluster network.
Host name and FQDN
Managed Service for PostgreSQL generates a name for each cluster host when it is created. This name will be the host's fully qualified domain name (FQDN). The host name and, consequently, FQDN cannot be changed.
You can request the host FQDN (name) with a list of hosts in the cluster.
To access a host within a single cloud network, use its FQDN. For more information, see the Virtual Private Cloud documentation.
Public access to a host
Any cluster host can be accessible from outside Nebius AI if you requested public access when creating or editing a host.
When deleting a publicly accessible host, the assigned IP address is revoked.
