Okay, thank you. I've been looking into Rabbit quite a bit. I like the stream processing aspect of Kafka, where you can introspectively peek into things as they happen rather than a straight message queue.
Some of our stuff is on the GCP, so have also been investigating Pub/Sub and DataFlow, which seem more viable since we don't have the up-front cost of hardware and maintenance but pay for resources used. If we don't use much, we should not pay much.
One thing to note about Pub/Sub vs Kafka. Pub/Sub does not offer as strict of guarantees around ordering as Kafka. If you don't need that strictness I'd definitely recommend Pub/Sub over Kafka but if you do I don't believe any of the Google Cloud Offerings will provide you that (Kinesis on AWS will).
