Hi @Shreekumar Suggamad ,
Thank you for your question.
The simplest way to achieve connectivity is to setup VNET peering between the AKS Vnet and the Kafka Vnet.
Please refer to this document for the steps on how setup the Vnet peering.
For more information about network peering please check this document, where it mentions:
For peered virtual networks, resources in either virtual network can directly connect with resources in the peered virtual network.
Let me know if you need anything else.
