AKS blue/green deployment pattern and kafka

Hi all,
I hope this is the correct channel for this question:
I have two AKS clusters running without Kafka, in two different regions - blue/green deployment on the cluster level.

How would I go about implementing Kafka into my AKS with the above mentioned deployment pattern and in-case of a fault in the blue cluster, our Front Door routes traffic over to the green cluster and continues carrying out the same work with kafka.

I hope this makes sense.
