Confluent Cloud Network on Google Cloud

Each Confluent Cloud network is a virtual network that is provisioned in your Confluent Cloud Google Cloud account.

You can create multiple Dedicated Kafka clusters within each Confluent Cloud network.

For details on default service quotas, see Network service quotas.

Prerequisites

Before you create a Confluent Cloud network, you need the following information.

Name your Confluent Cloud network

The name you choose is used to identify your network in the Confluent Cloud Console and when using the Confluent CLI. Choose a meaningful name, but consider including the connection type in the name (for example, My-GCP-CCN-1).

Select Region and Availability Zones

Dedicated clusters you create in your Confluent Cloud network inherit the selected Region and Availability Zones.

Select CIDR blocks

Select /16 CIDR blocks for your Confluent Cloud network on Google Cloud.

Review the following requirements for CIDR block selections:

  • The CIDR block must be in one of the following private networks, as mentioned in RFC 1918.

    • 10.0.0.0/8
    • 100.64.0.0/10
    • 172.16.0.0/12
    • 192.168.0.0/16
    • 198.18.0.0/15

  • The CIDR block cannot be the following:

    • 172.17.0.0/16

    Due to routing conflicts with Confluent services, CIDRs for your VPC cannot overlap with the above CIDR block. More specifically, you cannot peer the Confluent Cloud network with your VPC using the above CIDR.

  • Additional notes when selecting your CIDR block:

    • The RFC 6598 shared address space is supported on Google Cloud.
    • Must be a /16 CIDR block.
    • Cannot be modified after the Confluent Cloud network is provisioned.
    • Must not overlap with an existing Confluent Cloud network CIDR block.

Create a Confluent Cloud network on Google Cloud

To create a Confluent Cloud network, follow the procedure below for either the Confluent Cloud Console or the REST API.

  1. In the Confluent Cloud Console, go to the Network management page for your environment.

  2. Click Create your first network if this is the first network in your environment, or click + Add Network if your environment has existing networks.

  3. Select Google Cloud Platform as the Cloud Provider and the desired geographic region.

  4. Select the connectivity type: VPC Peering or Private Service Connect. Depending on the option selected, different Zone Placement options and CIDR for Confluent Cloud Network fields will appear.

    • VPC Peering: Cluster is accessible using the VPC peering endpoint.
    • Private Service Connect: Cluster is accessible using Private Service Connect.

  5. Complete the steps for the connectivity type you selected and then click Continue.

    Important

    After provisioning your new Confluent Cloud network, you cannot change your selected Availability Zone (AZ) IDs or CIDR block size. Make sure to deploy a network based on your zonal requirements.

    1. Under Zone Placement, select three zones for your network.

      Depending on the availability of supported zones, you might only have three zones to select.

  6. Under Create Network, specify the Network Name, review your configuration, and click Create Network.


Typically, it takes up to 15-20 minutes to create a Confluent Cloud network. Note the Confluent Cloud network ID from the response to specify it in the following commands.

Next steps

After successfully provisioning the Confluent Cloud network on Google Cloud, you can add Dedicated Kafka clusters within your Confluent Cloud network by using the following options:
