Peering Connections Overview

You can use VPC peering and VNet peering connections with your Confluent Cloud clusters. Review the following general limitations and any specific limitations that apply to your cloud service provider.

For details on peering connections for your cloud service provider, see the following sections:



Managed connectors created in a VPC-peered cluster can access data sources and sinks hosted in all peered VPCs, if the firewall rules allow connector traffic to and from the peered VPCs.

  • Transitive VPC and VNet peering are not supported. If you peer Network A to Network B, and peer Network B to Confluent Cloud, applications running in Network A will not be able to access Confluent Cloud. You can use shared Google Cloud and Amazon Web Services VPCs to enable transitive VPC connectivity. For more information, see AWS Working with Shared VPCs and Google Cloud Shared VPC overview. To achieve transitivity, you can also link an AWS Transit Gateway to a Confluent Cloud cluster in AWS.
  • You can colocate multiple Confluent Cloud Dedicated clusters in the same VPC. However, this is limited by the expected number and size of these clusters. The current limit for a private VPC is 50 CKUs, based on the limit for an environment. This limit and others are outlined in Service Quotas for Confluent Cloud.
