Service Quotas for Confluent Cloud¶
There is a maximum quantity of some resources and/or operations that can be used by organizations, environments, accounts, networks, and clusters in Confluent Cloud. This topic lists default limits, also called service quotas, for these resources by their scope.
Your organization can request that some limits be increased, and if a limit is raised, your organization’s applied limits may be different from the default maximums listed in this topic. You can check applied limits for your organization by using the Service Quotas API.
To request an increase for a limit, contact Confluent Support. Note that not all limits can be increased, and there are hard limits for all resources.
Organization quotas¶
The following table shows the default service quotas for the Organization scope. To query for the currently applied limits, see Organization quotas.
Resource | Default limit |

Network quotas¶
The following table shows the default service quotas for the Network scope. To query for the currently applied limits, see Network quotas.
Note
- For Kafka clusters and Kafka cluster CKUs, consuming more of one reduces how many of the other you can consume.
- For private networks, the organization and environment scope limits for the number of Kafka clusters and the number of CKUs are not applicable. To query for the currently applied limits, see Network quotas.
Resource | Default limit |
---|---|
Kafka clusters per peering network | 10 |
Kafka clusters per AWS PrivateLink or Azure Private Link network | 10 |
Kafka cluster CKUs | 72 |
VPC peering connections | 25 |

Azure subscriptions requesting Azure Private Link connections (no limit on number of connections) | 10 |
Transit gateway attachments | 1 |
