FAQ

Do Kafka Instances Support Cross-Subnet Access?

Yes. If the client and the instance are in the same VPC, cross-subnet access is supported. By default, subnets in the same VPC can communicate with each other.

Can Subnets Communicate with Each Other?

Subnets in the same VPC can communicate with each other. Subnets in different VPCs cannot communicate with each other by default. However, you can create VPC peering connections to enable subnets in different VPCs to communicate with each other.

For more information about network planning, go to the VPC Help Center.
