amazon-mq

Amazon MQ bills per broker instance hour — an mq.m5.large active/standby HA pair is ~$440/month before storage. Add EFS or EBS for the broker, and a typical production HA deployment lands at $700+/month with zero messages flowing. Use MQ only when AMQP, JMS, STOMP, MQTT, or OpenWire protocol compatibility is non-negotiable.

Standard SQS queues sustain nearly unlimited throughput per queue (AWS-documented pattern) while FIFO caps at 300 TPS per API batch without high-throughput mode—your May 2026 architecture review should start from those numbers, not from Kafka slogans.
