About NATS

NATS is a lightweight, high-performance messaging system designed for cloud-native and distributed systems. It supports core pub/sub, request/reply, and JetStream for persistent messaging with at-least-once and exactly-once delivery.

JetStream adds persistent streams, consumers, and key-value and object stores to the core messaging capabilities. It provides message replay, retention policies, and stream mirroring.

NATS is known for its simplicity and performance, with a single binary server that requires minimal configuration. It supports multi-tenancy through accounts and decentralized security.

The system is popular in edge computing, IoT, and microservices due to its small footprint, low latency, and support for leaf nodes that bridge edge locations to central clusters.
