Network in Managed Service for OpenSearch
When creating a cluster, you can:
- Specify a network for the entire cluster.
- Specify subnets for each node in the cluster.
- Request public access to connect to the cluster node groups from outside Nebius AI.
You can create a cluster without specifying any subnets for the nodes if the availability zone selected for each node contains exactly one subnet of the cluster network.
Node name and FQDN
Managed Service for OpenSearch generates the name of each cluster node when creating it. This name will be the node's fully qualified domain name (FQDN). The node name and, consequently, FQDN cannot be changed.
You can use the FQDN to access the node within a single cloud network. For more information, see the Virtual Private Cloud documentation.
Public access to a node
Any cluster node can be accessible from outside Nebius AI if you requested public access when creating its node group. To connect to such a node, use its FQDN.
You cannot request public access after creating a node group.
When deleting a node group with public FQDNs, the assigned IP addresses are revoked.
