Rabbit's federation is a good way to bridge point-to-point connections between geographically distributed systems. I'm not sure that's a great scaling pattern for throughput though.

The clustering might look tempting but it hasn't been resilient for me in the face of janky networks. Split brains and data loss can result.

In the past I've scaled my rabbits for throughput by implementing my own routing/sharding layer.

If you're tempted to use the message persistence and you care about retaining messages, kafka is a bigger but much more capable hammer.
