I’m a bit confused about option D; shared memory doesn’t seem right for microservices since they should be independent, right?

I think we had a practice question about Heroku and microservices, and I might lean towards option C because DNS Service Discovery seems like a good way to manage multiple services.

I'm not entirely sure, but I feel like option B could work too since Redis is a common choice for message passing.

I remember we discussed microservices in class, and I think option A sounds familiar since Kafka is often used for communication between services.
