NATS gains ground as teams rethink RabbitMQ

The article highlights the growing interest in NATS as an alternative to RabbitMQ among software teams building cloud-native, edge, and AI-driven systems. NATS Server 2.15, released on September 17, focuses on reliability and operations, with improvements in stream and consumer scaling, peer changes, backups, and source recovery.

Testing showed about a 10% increase in throughput under normal replicated-stream settings, with tail latency falling by more than 40%. NATS's communication model, based on lightweight subject-based publish-and-subscribe messaging and request-reply communication, is particularly appealing for AI applications and multi-agent systems where agents need to communicate dynamically.

While some organizations, such as Sophotech, have successfully migrated from RabbitMQ to NATS, citing significant improvements in latency and operational complexity, RabbitMQ remains actively developed and continues to address modern requirements, such as the release of version 4.3, which expanded quorum queues with strict message priorities and improved AMQP 1.0 support.
