AWS's messaging services are some of its oldest and most reliable: SQS for queues, SNS for fan-out, EventBridge for routing events by content between services and SaaS. They cost almost nothing at moderate volume and need nothing operated. RabbitMQ, available managed as Amazon MQ, brings flexible routing, AMQP and a protocol many existing systems speak. NATS, a CNCF project, offers very low-latency messaging and, with JetStream, persistence, and is popular for edge and IoT.
Question 1 of 2
Do existing systems speak AMQP or depend on RabbitMQ routing?
On AWS, default to SQS for work queues, SNS for fan-out and EventBridge for routing events between services and accounts — they scale without configuration and cost cents for most workloads. Use Amazon MQ for RabbitMQ when existing applications speak AMQP or depend on RabbitMQ's routing, rather than running RabbitMQ yourself. Use NATS when you need very low latency, request-reply patterns, or messaging that spans the edge, devices and cloud — and are ready to operate it.
