While clustering across wide-area networks (WANs) is discouraged due to latency issues, leased links can mitigate some connectivity challenges. Keeping queues short minimizes latency and enhances the overall efficiency of message delivery in RabbitMQ. Keeping queues short maintains a responsive and efficient RabbitMQ setup.

Balancing Low Latency, High Availability and Cloud Choice Cloud hosting is no longer just an option — it’s now, in many cases, the default choice. As a result, IT teams picked hardware somewhat blindly but with a strong bias towards oversizing for the sake of expanding the budget, leading to systems running at 10-15% of maximum capacity.
