NATS is a cloud-native messaging system designed to be lightweight and high-performance.

In this scenario, you'll learn how to start a NATS server and use it as a SUB/PUB message broker. The aim is to allow Microservices to communicate via NATS.

In this scenario we learned how to start the NATS Server, connect a client and use the protocol to SUB/PUB messages.

In future scenarios, we'll explore how to connect clients and use NATS Server within a Microservices architecture.

Visit http://nats.io/download/nats-io/gnatsd/ to download the NATS Server.

Don’t stop now! The next scenario will only take about 10 minutes to complete.
