Connect to External Systems

Confluent Cloud offers pre-built, fully managed, Apache Kafka® Connectors that make it easy to instantly connect to popular data sources and sinks. With a simple UI-based configuration and elastic scaling with no infrastructure to manage, Confluent Cloud Connectors make moving data in and out of Kafka an effortless task, giving you more time to focus on app development.

Source connector
A source connector, such as the Microsoft SQL Server Source connector, ingests entire databases and streams table updates to Kafka topics. It can also collect metrics from all of your application servers and store these in Kafka topics, making the data available for stream processing with low latency.
Sink connector
A sink connector delivers data from Kafka topics into secondary indexes, such as Google BigQuery or batch systems like Amazon S3, for offline analysis.

Note

Networking and DNS Considerations

Consider the following cluster network types when determining the public Internet access configuration for resources that fully-managed connectors must access. For Confluent Cloud networking details, see the Cloud Networking docs.

Important

To use static egress IP addresses, you must be running a multi-tenant or Dedicated cluster on AWS and on the public Internet (that is, without VPC peering, Transit Gateway, or AWS PrivateLink).

Cluster types and connectivity

The following tabs provide network connectivity details for managed connectors. Note that a Connect node runs in the same VPC/VNet as the cluster the Connect node was provisioned with. This is true for all cluster types (Basic, Standard, and Dedicated). For Confluent Cloud networking details, see the Cloud Networking docs.

The following information applies to a managed Sink or Source connector connecting to an external system using a public IP address.

Cluster network type Public IP address connectivity IP range used by the connector
Public Endpoint (AWS) Yes Fixed set of static egress IP addresses (see static egress IP addresses)
Public Endpoint (Azure and Google Cloud) Yes Dynamic public IP/CIDR range from the cloud provider region where the Confluent Cloud cluster is located
VPC Peering and Transit Gateway Yes Dynamic public IP/CIDR range from the cloud provider region where the Confluent Cloud cluster is located
Private Link Yes Dynamic public IP/CIDR range from the cloud provider region where the Confluent Cloud cluster is located

DNS considerations

Fully qualified domain names: Some services require fully qualified domain names (FQDNs) to access the service. In order for a managed connector to access such a service, the service must use public DNS records pointing to the IP address (public or private). Private DNS zones are not supported in Confluent Cloud.

Private service endpoints: Cloud service providers offer the ability to set up private endpoints with custom or vanity DNS names for native cloud provider services. Private endpoints are only supported if the provider supports resolving the endpoints using public DNS.

Confluent CLI

The CLI steps for managed connectors show examples using version 2 of the Confluent CLI. For more information see, Migrate to Confluent CLI v2.

API for fully-managed connectors

For information and examples to use with the Confluent Cloud API for fully-managed connectors, see the Confluent Cloud API for Connect documentation.

Cloud Console connector controls

You can use the GUI buttons to start, stop, pause, and delete a connector. Select and display one of your listed connectors to view the controls.
