What is the NATS messaging system?Link to this anchor

The Neural Autonomic Transport System, or NATS, is a distributed messaging system, designed to be lightweight and high-performance. It implements both of the following:

• A publish/subscribe model, designed for real-time messaging and notifications and event-driven architectures. This is ideal for communication between microservices.
• A streaming service via JetStream, providing persistence so that messages can be re-accessed after sending. The streaming add-on is ideal when applications require message replay or historical data access, such as event sourcing and audit logs.
