Single-node classic queue or three-node quorum queue cluster for low-traffic RabbitMQ
Goal: run a low-traffic RabbitMQ workload at the lowest practical infrastructure cost while retaining the ability to survive a node failure. A single node with non-replicated classic queues avoids replication traffic and fits on one small instance, but it has no automatic failover. A minimal quorum-queue cluster needs three nodes for a write majority, which
