Network in Managed Service for Apache Kafka^®

When creating a cluster, you can:

• Set the network for cluster hosts.
• Specify the availability zones where the cluster hosts should reside.
• Set subnets in all availability zones.
• Turn on public access to the cluster from outside Yandex.Cloud.

If hosts are present in the ZooKeeper cluster, each of the three ZooKeeper hosts uses its dedicated availability zone and the subnet selected in it. For more information, see Relationship between service resources.

Hostname and FQDN

Managed Service for Apache Kafka^® generates the name of each cluster host during creation. This name will be the host's fully qualified domain name (FQDN). The hostname and, consequently, the FQDN cannot be changed.

You can use the FQDN to access the host within a single cloud network. Read more in the Yandex Virtual Private Cloud documentation.

Public access to the cluster

All broker hosts in the cluster are available from outside Yandex.Cloud if you request public access when creating a cluster. To connect to such a cluster, use the FQDN of one or more of the cluster's broker hosts.

You can't request public access after creating a cluster.

When you delete a cluster with public access enabled, all public IP addresses assigned to this cluster are revoked.
