NATS can run anywhere, from large servers and cloud instances, through edge gateways and even IoT devices. Use cases for NATS include:

  • Cloud Messaging
    • Services (microservices, service mesh)
    • Event/Data Streaming (observability, analytics, ML/AI)
  • Command and Control
    • IoT and Edge
